I am delighted to report on the Electricity Unit's performance for the 2012/2013 financialyear. It was a challenging yet rewarding year, filled with technical difficulties and servicedelivery success.
The financial footing of the Electricity Unit was strong as we closed off for the year, yieldinga total of R 10.2 billion in sales. Eskom Bulk electricity costs accounted for R 6.4 billion ofthis, leaving behind R 3.8 billion to keep the electrical grid going and growing. With ageinginfrastructure in service, almost R 1 billion was dedicated to repairs and maintenance andthe balance spent on resources, general expenses and expansion/upgrade projects.
A key aspect of our integrated business plan is to expand our network and provide electricityto communities in need. Whilst balancing safety and technical criteria, we were able toelectrify a total of 15 informal communities since inception of the project in 2011. Wemanaged to complete 8 areas within this year despite, matters arising around land ownership,budget and internal capacity constraints. We are committed to continue withthe electrification program and will keep uplifting our communities in need.
Our electricity tariff increase was set at 11% for the year, with residential tariffs peakingat 9.8%. Business and Industrial tariffs saw a price hike of 12% on average. Relief for theindigent sector was provided in the form of access to Free Basic Electricity and a reducedtariff increase of 5.41%.
With the rising tariffs and the slow moving economy, we experienced negative growth(-) 0.44 % as opposed to the forecasted (+) 1% that we hoped for. Whilst sales are declining,we maintain a positive outlook. We are continuing with capital expansion programs, ensuringthat the network is available and in “tip top” condition to support the future recoveringeconomy. This includes moving towards Smart Grid technologies with the aim of optimizingour network control and efficiency.
Health and safety of staff is of paramount importance. We are pushing the boundarieshard, to ensure that safety is entrenched within the minds of all staff working on the network.Stricter controls and measures have been implemented, including a proposed DemeritSystem to address safety violations by contract service providers. We experienced anaverage of 15 safety related incidents per month, over the last year. Going forward, we arehoping that our new control measures will slash this number, helping us move closer to a“zero injury rate”.
In an effort to build capacity and promote skills transfer, we have embarked on a rigoroustraining program via the Work Skill Portal (WSP) to ensure staff is adequately preparedto work on the network. We are aiming to build technically competent individuals that areable to uphold the services, values and systems of the Municipality in a professional anddignified manner.
In conclusion, I want to salute my team for the unified support that they provided throughoutthe year. Whilst further challenges and obstacles are sure to cross our paths, we mustkeep on going, and not lose sight of our vision to make eThekwini the most caring and livablecity in Africa ……….

HV SUBSTATIONS BRANCHThe HV Substations Branch of HV Operations deals with the operation and maintenanceof equipment that has voltage ranging from 11 kV to 275 kV. There are five National keypoint substations that import energy from Eskom at 275 kV. The 275 kV is then transformedto 132 kV, 132 kV transformed to 33 kV and 11 kV, and 33 kV is then transformed to11 kV and in few cases to 6.6 kV. The types of equipment that the HV Substation Branchworks on, covers switchgear, power transformers, instrument transformers, busbars, surgearresters, lightning masts, and power line carriers. The different types of insulating mediumin circuit breakers are oil, vacuum and gas. The oil circuit breakers are of old technologythat render themselves uneconomical to maintain and unsafe to operate. Consequentlythey are gradually being phased out and replaced by vacuum and gas circuit breakers.
However there is still a large amount of oil circuit breakers present in HV substationsespecially at 11 kV and also at 33 kV. As a result more resources (staff, labour, material,and time) are spent on maintaining this type of switchgear.
A significant amount of plant is older than 30 years of age. There are frequent problemsassociated with their old age such as shortage of spares and mal-operation and severefailures. The decision was taken to phase out 33 kV plant and equipment because of ageand other associated problems such as unavailability of spares and multi transformation.The decommissioning of such plant and equipment has been made possible by constructionof new 132/11 kV substations.
HIGHLIGHTS� The diagnostic testing and condition monitoring programs have been improved.� The securing of Doble international contract to perform the transformer fleet screening.� The continuous Endeavour to do full maintenance of transformers and its ancillaries,
switchgear, isolators, and earth switches in HV yards and switchgear rooms.� The reduction of outstanding maintenance work orders.� The reduction of equipment that is out of commission.
LOWLIGHTS� The incidents of copper theft in HV substations are on the rise and they are threatening
substations' stability. The copper theft cases are occurring despite the existence ofSecurity guards in those substations that are manned.
� The delay in the installation of CCTV cameras in substations to deter the prospectivecopper thieves.
� The failure of three panels at City Central substations.� The outage at Congella substation due to the failure of glass disc insulator on the
132 kV busbar.� The outages caused by monkeys at Umbongotwini substation that feed one of our major
customers.� The delay in the restoration of the 315 MVA transformer at Lotus Park due to the
unavailability of the suitable tap changer in South Africa.� The Network protection mal-operations subjecting the plant to severe and lengthy fault
CHALLENGES� The maintenance of substation stability during this era of many cases of copper theft.
The copper theft has become a crisis.� The insufficient human resource to fulfill the requirements of the branch.� The supply chain management policy contributes to the delays in securing services
and products that help in restoring good condition of plant and equipment.� The usage of two different Enterprise Asset Management Systems (JDE and Ellipse) that
are unable to interface and resulting in delaying projects where Electricity work isoutsourced to Architectural Services. This also results in a lot of unnecessary paper work.
� The shortage of office space leads to difficulty in filling some critical posts.� The category 8 pay curve still poses a threat in the filling of critical posts such as electrical
Inspectors.� The condition and ageing of vehicle fleet.� Keeping the aged equipment such old oil circuit breakers, running.
� Lengthy procurement processes.� Difficulty in getting plant and equipment to maintain due to inability to shift loads to other
parts of the network. This problem makes it difficult to maintain plant and equipmentduring normal working hours. Hence increases overtime hours.
HV LINES BRANCHThe HV Lines Branch is responsible for the operation and maintenance of the high voltageoverhead line system presently consisting of 141 circuit kilometers of 275 kV,478 circuit kilometers of 132 kV and 13 circuit kilometers of 33 kV overhead line.
CHALLENGES:� There are still on- going theft of tower steel members in-spite of the division embarking
on increasing patrol on HV Lines.� Suitable off road (4x4) vehicles is becoming quite a challenge as the access roads are
becoming more difficult to negotiate with the encroachment of informal settlements anddevelopments within the power line corridors.
� Maintaining full compliment of trained staff is still a challenge due to high number of vacancies and movement within various departments and the country as a whole.
ACHIEVEMENTS:� The commissioning of the 132 kV Avoca substation in the north and the Kingsburgh
substation in the south, has reinforced the security of supply in the region, it has enabledus to eliminate 23km of 33 kV copper overhead line previously supplying this region,which was unreliable and continually being stolen.
� The Branch is in the process of finalizing the award of theft detection units which it willstart rolling out on our high risk strategic power lines with the proposed initial purchaseof 250. (Contrat E9135)
� Refurbishment project (E8960) is in progress with the following stages of completion• 275 kV Illovo - Lotus Park 90%• 275 kV Avon - Ottawa 35%• 132 kV Ottawa - Canelands 85%• 132 kV Durban South - Lotus Park 75%• 132 kV Bellair - Rossbrugh 60%• 132 kV Bellair - Mayville 10%• 132 kV Avoca - Tee Ottawa 10%
� All management and supervisory staff are attending PRAGMA asset management courseswhich is aimed at improving managing of assets and the utilizing best practices andpolicies and to meet GRAP 17 requirements
� One electrician has successfully achieved his switching authorisation up to 275 kV with4 more staff in the process of being trained.
� As part of improving skills of staff in the branch some of our staff have attended HV Linesmaintenance course , Infrared scanning course and also Design and construction course.
FUTURE PLANS:� In future the branch is looking at building a specialized line to assist with training of our
electrician and electrician assistants. This will be used for new HV Lines staff training onclimbing and working at heights safely.
� To purchase a 4X4 , aerial platform truck for easy & safe working at heights.
Also the awarded contract (E.8960) will continue to carry out refurbishment project. Inaddition to the above work in progress the following projects will be starting under thiscontract:1. 275 kV Ottawa - Durban North - Steel replacement and painting.2. 132 kV Durban North to Park Hill - Steel replacement and painting.3. 132 kV Tee SATS Canelands - Full refurbishment.4. 132 kV Tee Duffs Road - Steel replacement and painting.5. 132 kV Tee Marianridge - Steel replacement and painting.6. 132 kV Ottawa - Parlock - Steel replacement and painting.
HV CABLES BRANCHThe High Voltage (HV) Cables Branch is responsible for the maintenance and operation ofall 132 kV and 33 kV underground transmission cables, as well as all the 11 kV cables thatform part of the primary network infrastructure.
The chart below is an illustration of the cable system types and circuit lengths that thebranch is responsible for, as at the end of 2012/2013 financial year.
CHALLENGES� The maintenance of pressurised gas-filled and fluid-filled cables continues to be a problem
especially on the gas-filled cables. However, major projects are under way to replaceseveral unreliable cable circuits of this type in the near future. Some of these projectswill see unreliable gas-filled cable circuits viz Mayville-Huntley's Hill 1&2 and Mayville-Sydenham 2&3 decommissioned within 2013/2014 financial year. In 2012/2013financial year two of these gas-filled cable circuits were replaced with the reliable XLPEcable circuits. Although there is progress being made regarding these problematic cables,it will take some time before they are completely phased out of the network, thereforethe Branch is also investigating some short term solutions to efficiently maintain thesecables and solve problems associated with these cables, such as the bulk gas storagein order to reduce the frequency of gas re-filling, thus allowing electricians to focus moreon tactical maintenance.
� Cable jointing and terminating is a routine activity for the branch, this is intricate, timeconsuming and a specialised process. Over the past years this branch has been underpressure when it comes to performing these jointing and terminating duties due to issuessuch as resource availability and difficulty in hiring new skilled electricians due to thegeneral lack of skill in this field countrywide. To strengthen and enhance the skills of in-house electricians, the Branch appointed a specialist to conduct a week long theoreticaland practical training course for electricians. In 2013/2014, the Branch intendsorganising more of these courses which will be highly beneficial more importantly to thenewly appointed electricians.
HIGHLIGHTS AND LOWLIGHTS� In 2012 - 2013, the Branch experienced an unprecedentedly high number of 132 kV
fault, with three faults on 132 kV fluid-filled cables and two faults on 132 kV XLPE cables.Although two of these faults were a result of third-parties (damages and theft), three ofthese faults were cable electrical faults which highlighted the need for the Branch tofocus more on tactical maintenance in order to prevent these faults before they occur.
� The Branch also went out on a public tender and appointed a contractor on a genericmaintenance contract that, moreover jointing and terminating, includes other type ofwork that is frequently performed by the branch. This will assist in reducing the overduemaintenance and ensure that more focus is on tactical and preventive maintenanceinstead of non-tactical and reactive maintenance.
FUTURE PLANSIn 2013 - 2014 the Branch will give more attention in researching and evaluating thediagnostic testing equipment for 33 kV and 132 kV cables. Once the Branch has identifiedthe technically and economically viable equipment, this will be budgeted for and purchasedin order to undertake diagnostic testing of cables to reduce the risk of unplanned and costlyoutages. The Branch also intends purchasing the ready-to-use stand-by cable links that willbe used to bypass 'some' substation equipment during maintenance and or repair operations,offering the continuity of supply to maintain end-consumer satisfaction and avoid businesslosses.

HV NETWORK CONTROL BRANCHThe Network Control Branch comprises of four Divisions: HV Network Control, SystemPerformance, Network Management and Control Systems.
The HV Network Control Division is responsible for the safe operation and efficient performanceof the High Voltage Network, which incorporates a 24-hour, manned HV Network ControlCentre with remote control and alarm facilities. eThekwini Electricity's primary transmissionnetwork, being the supply from 275 000 V down to 6 600 V, is monitored and controlledfrom this Control Room using a sophisticated Supervisory Control and Data Acquisition(SCADA) system.
The System Performance Division is responsible for network optimization, ensuring the HVNetwork can meet the demand for electricity, statistical reporting and quality of supply tothe bulk supply points for the 11 000/6 600 V distribution system and large industrialcustomers that are connected directly to the HV network.
Network Management and Control Systems Divisions are responsible for the planning,operation, maintenance and reinforcement of systems to monitor, protect and control theUnit's primary supply infrastructure.
HIGHLIGHTS AND LOW LIGHTS� The new quality of supply management system has proven valuable to customers and
the HV Network Control Division. The system includes a new custom-built performance analysis tool.
� A legacy Remote Terminal Unit (RTU) replacement program is well underway. To date,30 % have been substituted with state-of-the-art hardware featuring increased functionalityand provision for electrical network expansion.
NEW TECHNOLOGIES� To improve quality of supply to customers, the Branch has commenced a drive to roll out
remote master trip resets which will facilitate improved remote restoration of supply.� The Branch is investigating the Fault Detection Isolation and Restoration (FDIR) tool t o
limit/prevent the amount load lost when a network fault occurs. The reduced risk of loss of supply on the HV network will permit a higher volume of maintenance.� The Branch is finalising the incorporation of Under Frequency Load Shedding (UFLS) into
the Integrated Control and Protection (ICAP) system which will ensure eThekwini Electricitysheds the required amount of load during an under frequency event to prevent a nationalblackout.
� With different branches utilising various applications and platforms, data transfer fromSCADA system to other application platforms has become necessary. The Branch iscurrently establishing a data exchange server to facilitate bi-directional real-time datatransfer between SCADA platform and other applications within the organization.
� Using existing communication systems infrastructure, the Branch is investigating thefeasibility of Integrated Volt-Var Control (IVVC), to minimize losses and manage voltagewithin an acceptable range.
� The Division has also embarked on a cyber security drive over the last year. A securitypolicy has been drafted for phase one of the security audits which will begin in early 2014.
CHALLENGES� Staffing of the HV Control Room continues to be a challenge given that Eskom and other municipalities compete for a very small pool of scarce skilled employees.� EThekwini Electricity faces the same security challenges as other major electricity
distribution organizations in South Africa. Theft of plant and equipment from substationsis a growing concern and the Branch is embarking on the following projects to combattheft:- An organization level substation security policy is currently being developed and compiled.- Closed-Circuit Television (CCTV) camera system is currently being rolled out at substation
sites. These cameras achieve high resolution and perform world class video analyticswhich then enables the business to achieve a high apprehension rate as well as make
provision to study break-in loopholes within the substation infrastructure.- Upgrading the existing access control system with a design improvement based on
current experience and security systems best practice.
The MV/LV Operations Department is responsible for the planning, construction, operation and maintenance of the Unit's
medium and low voltage network. The department plays a major role in connecting new customers to the electrical grid
thus helping to spread electrical services to all sectors of the community. The department is also responsible for providing
public/street lighting and has a strategic focus of introducing new and improved energy efficient lighting technologies into
the city. Further to the above roles, the department manages and controls all medium to low voltage substations.
Advancements in technology with the benefit of cost/operational optimization is driving significant changes in the

NETWORK CONTROL BRANCHThe reliability of our electrical network is vitally important as disruptions in power supplyleads to economic losses, lost productivity and it affects public health and safety. The NetworkControl Branch closely monitors network performance and manages incident responseson a twenty four (24) hour basis. We play an important role in providing solutions to ensurethe security, stability and continuity of supply to eThekwini Municipality's area of supply. Ourdedicated team are responsible for running the electrical network and in the event of asystem disruption, we must respond appropriately and promptly to facilitate the co-ordinationof the system and customer load restoration.
The various contributing factors to power outages include theft on our network, inclementweather conditions and defective equipment. For the period under review the following faultswere attended to;
Type of Fault Number of incidents
Individual Faults 251 011
LV Faults 10 272
MV Faults 5 683
Total 266 966
HIGHLIGHTSWe take pride in providing dedicated teams and standby staff at special events such asElections, Conventions and Sport Tournaments. Our staff works behind the scenes toensure a stable power supply and backup power where necessary.
Last financial year the project for new offices for the Faults Division of Network Controlreached completion. We are pleased to announce that the staff moved into the new premisesin Springfield and the operational efficiencies have pleasantly improved.
CHALLENGESThe growth in the demand for electricity is ever increasing given our population growth andthe exponential increase in the number of power-hungry digital components, bigger houses,air conditioners and computers. However as demand skyrockets, further limiting efficiencyand reliability of our network, there is a need to reinforce and upgrade our electricinfrastructure. The evolution of the Smart Grid has the potential to transform day to dayoperations of Network Control. A Smart Grid enables vastly improved system reliability.Distribution operations will become proactive instead of reactive, identifying and repairingequipment, cables and lines before failure occurs and shedding load to operate within designlimits of transformers, circuits, and substations.
Theft on our electrical network is still on the rise, resulting in delays in service delivery toour consumers.
One of the main threats is that of copper conductor theft and it is estimated to be in excessof R 5 billion a year around various municipalities within the country. We currently assistthe SAPS to identify cable at the scene of thefts and report all cases of cable theft to theSAPS when they are discovered while attending to faults. The Southern African RevenueProtection Association (SARPA) have proposed a cable marking standard initiative and inaccordance with the new Second Hand Goods Act there will be no loopholes when prosecutingsuspected thieves in the future as the copper conductors will be easily identified.
FUTURE PLANSThe implementation of an Advanced Distribution management System (ADMS) made upof Outage Management (OMS) and Distribution Management (DMS) systems will dramaticallyincrease efficiency and form the bridge between engineering reality and emerging consumerneeds. As staff in the control rooms gain access to more and more data, they will needtools to convert the data into actionable information for visualizing what's going on, spottingproblems and exceptions, remotely controlling equipment, handling outages, and planningahead. Real-time and historical data will be fed into asset management, workforcemanagement, outage management and back office functions to gain cross-functional processefficiencies. In the forth coming months we will concentrate on fully implementing the newsolution, integrating it with other key operational systems, and train our operators and usersof the new solution.
In the year ahead, we will embrace a shared vision for significant technology and businesschanges in order to ensure an acceptable quality of supply and service to our fellow citizens.
CONSTRUCTION PLANNING AND WORKS BRANCHEThekwini Electricity has taken a decision to improve the lives of the poorer communitiesby providing electricity to transit facilities and informal settlements. The electrification grantfrom the Department of Energy assisted in electrifying 9,986 low income and informaldwellings so that at least another 40,000 people can enjoy a better life. 1,069 non-prepaidsupplies were provided to other residential developments within the eThekwini municipalarea.
HIGHLIGHTS AND LOWLIGHTSThis Branch spent 92% of its operating budget of R111million, and overspent the capitalbudget of R197million by 12%. Some of the major capital projects include:
� Rerouting of medium voltage circuits from the Illovo, Smithfield and Winkelspruit33/11 kV substations into the recently commissioned Kingsburgh 132/11 kV substation
� Laying circuits from Northdene 132/11 kV substation to re-inforce the Sarnia/Pinetownareas
� Re-configuring the medium voltage circuits in the Overport/Sydenham/Springfield area� Installation and commissioning of 11kV switching stations� Upgrade of voltage from 6.6 kV to 11 kV in the Umbilo area
During the year there were four minor accidents and two disabling injuries within this Branchand achieved a 5 star safety rating.
CHALLENGESWhile we have managed to attract a few more employees the Planning and ConstructionBranch still has 58% of its posts vacant. Vacant positions include Electricians, Techniciansand Engineers. The Branch relies on the services of Consultants to process applicationsfor new connections and manage the installation of service connections. Contractors havecontinued to complement our staff in implementing our infrastructure projects. The effortsof all our staff and agents are greatly appreciated.
MAINTENANCE BRANCHThe Maintenance Planning and Works Branch is responsible for inspection, maintenanceplanning and maintenance implementation on all medium and low voltage apparatus as wellas repair of associated faults on the electrical distribution network within the municipalsupply area. This Branch comprises of six regional works depots and a Maintenance PlanningDivision based at the Electricity Headquarters. The Branch consists of a Senior Manager,Managers, Specialist Engineer, Engineers, Technicians, Electricians and the various levelsof administration and assistant staff.
The Maintenance of eThekwini Electricity's distribution network is vital in ensuring the integrityand reliability of supply to our large customer base. This Branch prides itself on highstandards and strives to comply with various national standards and the Power QualityCharter in order to meet the requirements of customers. The major challenge facing theBranch is the growing pandemic of theft of electrical infrastructure.
CHALLENGESThe growing global need for non ferrous metals such as copper has resulted in high volumesof theft of electrical infrastructure both locally and abroad. The net result for this Branchis that it theft has significantly increased the workload, maintenance budgets had to besignificantly increased, supply restoration times have increased and the integrity of theelectrical network becomes compromised. The Electricity Unit is however investigatingvarious methods of monitoring and dealing with the scourge of theft. Rapid growth of theelectrical network coupled with the shortage in human resources and an increase in failures,has resulted in significant backlogs of planned and preventative maintenance work. TheBranch has undertaken an aggressive recruitment drive, during the year under review tobolster its internal resources and reduce the reliance on external service providers.
Various appointments were made at all levels and the staff vacancy levels have significantlyreduced. The technical staff will however, need to go through a mandatory pre-competencyperiod before they are deemed to be fully functional and are able to work independently.
The Branch is in the process of researching various technologies that may assist with theextremely challenging conditions and the immense workload. Our Engineers are currentlyinvestigating cable and switchgear diagnostic systems that will assist in the conditionmonitoring of these apparatus. Various options are also being looked at in order to assistwith vegetation management and control.
While the network is reliable, the branch realized that there is still a room for improvement.One of the factors contributing to the reliability is the construction practice, which usedbare (un-insulated) jumpers to connect MV overhead equipment (e.g. Pole Transformer,Auto-recloser and Sectionaliser) for distribution of electricity. Problems arising from thisare high number of faults due to electrocution of animals, birds and snakes. To resolvethese problems, the branch conducted market research and tests which resulted in coveringof bare jumpers using LDPE pipe (flexible water pipe with UV rating). Mount Morelands wasidentified as one of the areas with high animal/birds electrocution and power interruptions.A pilot project was undertaken late last year (2012) in this area in which five Pole Mountedtransformer jumpers were covered. No single animal/bird electrocution case was reportedto the branch by residents and no power interruption due to monkeys or birds was registeredsince then. The branch then took decision to roll out the covering of bare jumpers throughoutthe network in areas with high animal and birds activities.
The Branch has seen a significant increase in maintenance expenditure over the past fewyears. This figure has increased significantly, especially during the past five years and is nowin excess of R400 million per annum. This increase in expenditure was mainly due to aconsiderate focus on fault rectification caused predominantly by ageing network, third partydamage, theft of infrastructure, vandalism and the acquisition of external service providerswhich has resulted in reduced levels of workmanship. The co-operation of internal staff,consultants and contractors in delivering an acceptable level of service to our customersis vital in ensuring that this Branch meets it objective.
LIGHTING WORKS BRANCHLighting Works Branch is responsible for construction and maintenance of about 200 000streetlights in the whole of the eThekwini Municipality area of supply. The Branch is constantlybeing challenged technical in dealing with theft related faults, which are forcing the technicalinnovation of the branch to come up with ways and means of minimising theft. Though thecurrent situation has not changed much but the theft rate has decrease.
The Branch bid farewell to one of its long serving superintendent who managed theconstruction division of Lighting Works. The Branch highlight was the successful completionof an OHM competency by one of our electrician and with the third one embarking on thesame exchange programme as a skills improvement. The Branch welcomed a new electrician.The Branch achieved an overall 5 star NOSA rating the financial year. The set target of70% turnaround time on faults/complaints received and attended to within five workingdays is still a priority in ensuring service delivery to the municipality supported by the currentlyrunning maintenance and construction contract E 9103.
LIGHTING PLANNING BRANCHThe Lighting Planning Branch is responsible for the planning, design, inspection andmaintenance planning of the public lighting infrastructure for the eThekwini Municipality.This includes the planning and design of new lighting installations, upgrading of existinglighting infrastructure, research and investigation into new lighting technologies and bulklamp replacements.
A major responsibility of this Branch is the planning and design of capital projects. Theannual capital budget for the financial year under review was R27million and projects wereplanned for upgrades from conventional technologies to LED streetlighting, major routeimprovements, new major routes, lighting of parks and sundry lighting. Grant funding ofR20m was received from EEDSM for the installation of LED streetlights to replace the80 W mercury vapour luminaires in residential areas, 150 W high pressure sodiumluminaires on secondary roads and 250 W high pressure sodium luminaires on mainarterial roads. Other major projects for the current and future financial years include; IllovuRoad (Kwamashu), Newlands East Drive, Umgeni Road/N2 Interchange, Church Road(Westville) completion of MR 577 (Kwadebeka), School Road (Verulam), Wadd Street(Tongaat), Hlongwane Road (Bothas Hill), M4 Ruth First Northern Freeway, Inanda Road(Waterfall) and floodlighting for ablution facilities in informal settlements.
A majority of the projects undertaken by the branch involves intense interaction with otherservice units and external entities such as Roads Provision, Architectural Department,Parks, Leisure & Cemeteries, Roads and Stormwater, Strategic Projects, Tongaat Hulettsand a host of developers and external electrical consultants.
The Branch plans and designs conventional and special lighting projects for these entities,and takes into account any specific requirements for each of them.
The Branch operates on an annual budget of approximately R20 million, taking into accountsalaries, allowances, general expenses, repairs and maintenance. Repairs and maintenanceaccounts for 80 percent of this operating budget and this is further broken down intoplanned lighting maintenance, bulk lamp replacement and pole painting. There are currentlyapproximately 187 000 streetlight installations, 49 cemeteries, 250 parks, 12 beaches,17 subway lanes, 31 swimming pools and 93 stadia and sports fields for which themunicipality is responsible and provides lighting for.
With energy efficiency still remaining a hot topic globally, the branch continues to dedicateresearch and investigation into energy-efficient lighting solutions. Technology such as LEDlighting is being hailed as the future of lighting and is becoming increasingly present in thelighting environment. Consumers have shown a great appreciation of this “new” white light.In addition, the branch is considering a telemanagement system of lighting control wherebylighting levels along major routes could be reduced by dimming for that part of the nightwhere traffic volumes are minimal. These systems also have the facilities of added monitoringof lighting infrastructure which could significantly assist with the spiraling scourge of theftand vandalism
The Branch has recently achieved an acceptable staff compliment and we now aim to workon building their skills and experience within the Division. The long-term goals are to initiatecomplete audits of all public lighting systems and undertake the necessary upgrades andimprovements thereof.

PRICING AND MARKETING BRANCHThe electricity Pricing & Marketing Branch has several primary functions namely:� To raise awareness about key issues involving electricity� To provide a technical and admin service to our key customers� To design cost-effective and accurate electricity tariffs� To maintain a statistical database for electricity purchases and sales and other important
Energy conservation and management have become key concerns in the industry due tothe repercussions of the recent energy crisis. Technical and non-technical loss managementstill remains one of the top agenda's for the Branch.
PRICING DIVISIONThe Division designs electricity tariffs and provides tariff advice to key customers. Tariffsare designed to be cost-effective whilst ensuring accurate cost recovery and reflectivity.The overall average tariff increase as approved by NERSA for 12/13 financial year was8% however individual customer categories were increased as follows:
Tariff design is proving to be a major challenge in the midst of the huge increases fromESKOM and we are finding it more difficult to design cost reflective tariffs that are affordableto the end customer. Major emphasis has been placed on protecting the poor to ensurethat they are not adversely affected by the huge increases. The tariff increases have beencalculated in line with NERSA's guideline methodology.
Table below compares the Average Percentage Increase of the electricity tariff in 2012/13for several Municipalities.
City Average Percentage Increase
Cape Town 11 %
Ekurhuleni 11 %
eThekwini 11 %
Johannesburg 14 %
Tswane 12 %
HIGHLIGHTS AND LOWLIGHTS� Two much needed technical staff members joined the Pricing Division� Pricing was able to prevent the introduction of IBT tariffs. In eThekwini the implementation
of IBT would negatively impact poor and low income Households where more than onefamily lives on a property.
� The Pricing Division was capable of charging Free Basic Electricity at NERSA's recommendedguidelines.
� A no cost charge for 20 A prepayment meters were designed and implemented at theend of the financial year.
FUTURE PLANS� Lack of knowledge about FBE is of great concern in the department and new key strategies
will be implemented to try increasing our FBE customer band for the 2013/14 financialyear.
� The initiative for electrification of informal and rural settlements tariff was approved andwill be available in 2013/14 financial year
� The Eskom maximum demand rules were introduced with the intention of finalisation inthe next financial.
� Due to the drive for “Green” Electricity the need is arising for the Division to implementEmbedded Generation tariffs for residential customers.
MARKETING DIVISIONThe Marketing Division is continuously holding interactive events to raise awareness andpromote the ideals of the Department. Knowledge of reducing energy consumption throughbehavior and technology is being promoted by the marketing staff and starts at primaryand secondary school levels.
The activities of the Marketing Division create a platform to engage with the public to addressthe following:� Energy efficiency and demand side management (DSM)� Service delivery problems and constraints� Theft of electricity and infrastructure� Free Basic Electricity� Electrical safety and electricity hazards
EThekwini Electricity has brought joy to many families after achieving their first phase goalsof electrifying rural and informal households. The total informal households connected tothe network reached 2 439 houses
The table below indicates electrification projects completed in 2012/13:
Ward No. Name of Settlement Households Project Statusconnected tothe network
69 Chartsworth Bay View (Emanyaleni) 204 houses Completed

23 Permary Ridge 150 houses Completed
16 Nazareth Extension 84 houses Completed
83 Zakheleni Area (Umalzi betweenComtech and Mangosuthu ) 385 houses Completed
The Marketing Division has also been working closely with communities and the internalplanning staff to try and asses the feasibility of electrifying areas that are without electricity.There are numerous challenges to overcome before all citizens are electrified however theBranch is committed to make this a reality in the coming years.
REVENUE PROTECTION BRANCHRevenue Protection Strategy is a systematic, on-going process, and not a once-off operation,whereby utilities need to proactively identify and target consumers that actively contributeto revenue losses, and to take the necessary action in order to minimise these losses. Thepillars of successful revenue protection are People, Processes and Technology, which needsto be integrated into a Revenue Protection Strategy.
HIGHLIGHTS AND LOWLIGHTSThe following projects and technologies have been implemented by eThekwini Municipalityto enhance Revenue Protection.� Installation of Prepayment Meters (Split)� Meter Management and Operation System� Use of Digital Pen & Paper Technology� Use of Protective Structures for meters and equipment� Audit of Business Customers.
These projects contributed to the success of eThekwini Electricity's efforts in keeping totallosses to below 6%, which is well below the national and international benchmarks.
INSTALLATION OF PREPAYMENT METERSThe installation of a prepayment metering system and the principle of debt collection via aprepaid meter played a crucial role in affording the poorest of the poor access to basicservices, in the process partly alleviating the problem of non-payment of services. It is criticalthat one devises strategies that are complementing each other to ensure sustainability.Encourage these customers to install prepayment meters due to the following advantages:� Can budget for the cost of the usage of electricity;� Can purchase electricity for as little as R5; there are no shocking bills at the end of the
month; you use only what you can afford, and pay for it in advance; your meter indicateswhich appliances use a lot of electricity; your meter indicates the credit you have left inyour meter;
� When your electricity runs out, your meter switches off automatically. Thus, you will notincur any debt by using electricity for which you have no money for, as with the creditmeters.
� Also there will not be any reconnection fees, penalties and interest charges, as there willnot be any arrears; etc.
SPLIT PREPAYMENT METERS THAT USES POWER LINE CARRIER (PLC) TECHNOLOGYThe split prepayment meter that uses power line carrier (PLC) technology is the electricityprepayment system that totally eliminates the need to install a dedicated communicationscable. Instead, communication between the externally fitted Remote Energy Dispenser (RED)and internally installed Customer Interface Units (CIU) is achieved via existing mains cables.
This means that when you need to retrofit conventional meters that were installed usingcables without a dedicated communications cable, there is no need to retrofit house servicemains with communications cable.
The ability to use standard household wiring makes this an extremely attractive and cost-effective technology ideally suited to the retrofitting or replacement of conventional meters.We decided to install split prepayment meter that uses power line carrier (PLC) technologyin some areas.
REMOTE ACCESS SOLUTION - BENEFITSIn addition to the benefits of split prepayment metering, it offers two way communications,improved revenue protection and fraud detection of the prepayment meters with benefitssuch as:� Fraud notifications (e.g. tamper condition)� Auditing the prepayment meter remotely� Interrogate individual meter registers� Graphical display of consumption patterns� Power failure notifications from the mini-sub� Check metering to determine non-technical losses� Reports on low consumption� Two way communication with the prepayment meter - send maintenance tokens to the
THE REMOTE ACCESS TERMINAL (RAT)� The RAT is a three phase PLC Data concentrator� Is able to monitor the PLC meter communications between the meter and its Customer
Interface Unit� Real Time Clock (RTC) functionality

METER MANAGEMENT AND OPERATION SYSTEMEThekwini Electricity invested in a structured Revenue Protection department, with threeregional offices and field teams, reporting to each office. They are focusing on reducinglosses over the entire meter-installation base, but the inherited challenges faced with thepre-payment system made it difficult to get “ahead of the game”. The following were requiredto address this challenge:� One Central Master System that reconciled all records� A structured field audit with the aim of normalizing all pre-payment and as well as residential
credit meter records� An integrated Work Order system to manage all follow-up field operations and record
updates� Data Reporting and Data mining to plan and execute a pro-active Revenue Protection
With more than 319 000 prepayment meters under our management, field operationsand data management could quickly become a daunting task. A high level of data validationand seamless system integration would be required.
The field operations consisted of two separate, but integrated actions. The first action wasthe physical meter audits. The primary aim of the audit was to update the meter recordsand to identify each meter position with an accurate GPS coordinate. The audit teams wouldfirst finish the work in a small designated area before the second action was initiated. Thisfollow up action was to address all required remedial field work identified by the initial audit.These operations were executed by a separate specialised normalization team. Theadvantages of this approach included:� The audit team could focus on the data acquisition and their productivity was optimized.� There is a negative impact with limited access when tamper disconnections are started. By first completing the audit sweep the access rate was much higher.� Fraud was limited since there was no imputes to bribe the audit team not to report
anomalies. The audit team had no direct contact with the normalization team.� The normalization team's skill set was selected towards the remedial tasks to be performed.
An electrician's time was not wasted by being held back by the overhead of a full dataaudit.
We embarked on a program to normalize our prepayment data set and in parallel launcheda paperless works order system to follow up on all remedial tasks identified through thisproject. We are now in the position to run an intelligent revenue protection program basedon back office analysis and targeted inspections. The positive results are already evidentand the future returns should be even greater. The success of the operation can be measureby having the correct building blocks in place comprising:� People - A project can only be effective with committed and dedicated resources� Processes - The correct processes and procedures established at the start of the project
are essential� Technology - This is the last element, but it is only effective once the first two pillars are in place. Investing in technology on its own will not ensure success.
PROTECTIVE STRUCTURESIn some instances Meter Room doors (Steel) are vandalised. As a result, customers werecontinuously tampering with electricity meters and illegally or dangerously connecting cablesonto our electricity supply network.
In areas where vandalism is rife we decided to install Vandal Proof Meter Room Doors orProtective Structures with an electronic locking system. These Structures are designedwith external hinges and an internal locking system. The design is such that with the hingesremoved the door cannot be opened
� Asset Protection to ensure minimal energy losses (non-technical)� To prevent unauthorized access and damage.� Enclosure has a high security features.� It can be monitored and controlled remotely.
SECURITY: ELECTRONICS� Communication via GPRS to control� Separate locking system for LV and MV doors� All entries are logged� Monitor alarms remotely� RFID key tags for restricted access which is monitored� Optional (Only 1):
- Heat sensors to detect a cutting torch- A daylight sensor - indicate any access- Vibration sensor to detect drilling
DIGITAL PEN & PAPER TECHNOLOGYDue to the increase in electricity tariffs over the past few years and the fact that eThekwiniMunicipality uses the concept of consolidating accounts, we have seen more and more ofeThekwini Municipality`s customers struggling to pay for their consolidated accountstimeously. As a result, over the past few years we have seen a steady increase in the numberof arrears disconnections.
It is therefore very important to effectively and efficiently disconnect customers that arein arrears to tighten our Credit Control Policy. EThekwini Electricity uses an advanced form-processing solution using highly evolved Digital-Pen-and-Paper Technology to effectively &efficiently manage the disconnections. This technology helps us to track the activities ofdisconnectors, i.e. auditing work carried out by contract disconnectors and to transfer thedata from the field to the office instantaneously.� We are able to audit contractors to ensure compliance - The Form Viewing / Editing
System: GPS Mapping System - Reporting and monitoring of field staff.� Monitor Contractors and/or staff performance- The Form Viewing / Editing System:
Filtering and Search Tools.� Payments of contractor`s Invoices - Reports.� Simple Technology - Pen and Mobile Phone.� Real Time Reporting and Real Time Monitoring of electricity disconnections.� Ability to attach photographs which can be uploaded to the system.� Digital Document Archival.
AUDIT OF BUSINESS CUSTOMERS (CT DRIVEN INSTALLATIONS)The annual financial losses to energy suppliers caused by connection errors in meterinstallations are not to be neglected. There are many possibilities in making incorrectconnections during installation. In many cases, installation faults are rarely discovered atthe time of billing and, sometimes, not recognised for many years. This results in considerablelosses to energy suppliers.
In the energy market the meaning of correct energy billing becomes even more important,especially because more parties are involved in this process.
It is imperative that utilities provide the necessary training to the Revenue Protection andMeter Engineering staff, set out procedures for the re-commissioning and verification ofmeasurement and metering equipment and to provide the standard tools and test equipmentrequired by technicians to perform their tasks to ensure that the required safety and/orquality standards are practiced.
The policy that defines the criteria regarding planned maintenance on electricity meteringand measurement equipment needs to be adopted to ensure that utilities comply withNRS 057 and the Electricity Metering Code of Practice.
The Revenue Protection branch conducts annual audits to verify measurement andmetering equipment and analyses circuit faults found during the verification.
STRATEGYThe strategy adopted is to ensure that the Revenue Protection & Meter EngineeringBranches work hand-in-hand and have the resources, equipment, skills and ability, to carryout re-commissioning and verification of measurement and metering equipment and tomaintain a high level of equipment security by sealing the metering equipment with appropriateseals in accordance with the Code of Practice of eThekwini Electricity on the sealing ofmetering equipment.
CIRCUIT FAULT IN METER INSTALLATIONSThe “Circuit faults “ means that there is a fault that affects the correct functioning of themeters, but does not affect the supply to the customer (i.e. wrong connections, open circuits& short circuits). For this project, the audit inspectors go beyond just identifying “Circuitfaults” but they also identify any tampering that might have taken place on the meteringand measuring equipment and they also do an office audit on each installation`s documentationto verify the following :
� Correct meter number captured.� Correct CT ratio programmed on meter.� All CT currents are present.� Correct VT ratio programmed on meter.� All voltage phases present.� Correct tariff used.� Condition of meter panel.
A shortage of resources remains a challenge in the industry but despite these challenges,correct meter reading is vital for utilities to avoid a loss in revenue. EThekwini Electricityuses experienced and qualified staff or consultants to perform all the necessary auditinspections to ensure that meter errors do not go undetected.
METER ENGINEERING BRANCHThe core responsibility of the Meter Engineering Branch is to ensure all metering equipmentused for billing purposes are appropriately specified, tested, installed and maintained. Toensure these objectives are undertaken efficiently, the Branch is sub divided into fourspecialized Divisions. These Divisions are Advanced Metering & Projects, Metering Workshop,Whole Current Metering (Construction and Maintenance), and the Bulk Metering Division.
ADVANCED METERING AND PROJECTS DIVISIONThis Division is fundamentally accountable for the acquisition, specification and commissioningof new metering technologies. During the past year, this Division has been involved in theimprovement of automated meter reading systems communication equipment, reducingthe total number of manual reads to 1.04%. These systems make use of cellular wirelesstechnology via GSM for the remote acquisition of metering data back to the master stationsfor billing purposes. Updated GPRS/RF wireless technologies are currently being investigatedas possible alternative means of wireless communication. These later technologies canpositively add to the Division as it is a more cost effective and reliable alternative for futureapplication. The most recent technology update currently being added to the system is theremote metering failure notification system which is programmed into the meter to notifythe Division’s staff of any metering failures via SMS.
Another important project currently being undertaken by the Division is the implementationof smart metering for both residential and industrial use. The most recent advancementto this has been the appointment of Smart Metering Management Consultants. This teamof experienced professionals will work closely with the municipality management and lookinto the various solutions of integrating the concept seamlessly into the municipality'sstructure. The Division is also continuously working with ESKOM on multiple load controlprojects to ensure a healthy national grid during times of high demand. The Advancedmetering Division also has been given the sole responsibility of programming all electronicmeters for every tariff application.
THE BULK METERING DIVISIONThe Bulk Metering Division is responsible for all new applications and upgrades for themetering of large power users. This involves complex meter installations and maintenance.The division is directly responsible for the generation of metering data and maintenanceof nearly a 1 000 of our largest customers which makes up around 50% of the total revenuegenerated by the electricity department. In addition, the Division undertakes planning;forecasting and more importantly execution of load profile requests for tariff analysispurposes for our business customers who would like to migrate to more favorable tariffs.
The Division is also responsible for the migration of summation systems to the multi-feedersystems, thereby improving accuracy of metering and ensuring precise revenue collectionis being continued. The Division is also responsible for the scheduled meter replacementsand changes. This includes replacing all electromechanical and outdated electronic bulkmeters with the later version electronic bulk meters.
THE WHOLE CURRENT METERING DIVISIONThe Whole Current Metering Division is further divided into maintenance and constructionin order to optimize turnaround time due to a significantly larger consumer base. ThisDivision is fundamentally responsible for all new metering applications, upgrades, reinstates,credit to pre-paid changeover of small businesses, commercial and sectional title residentialcustomers. Rectification of onsite faults and queries on all complex metering installationsalso forms a significant part of the Division's responsibilities
THE WORKSHOP DIVISIONThe principal function of this division is to test, repair and calibrate all single phase andthree phase electro-mechanical meters. The Division is also required to carry out testingand servicing of pre-payment, three phase and single phase electronic meters. Further tothe above duties the Division provides critical support for equipment quality assurance bysample testing 10% of all new meters purchased.
This Division has an approximate average throughput of 400 single phase, 200 three phaseand 1300 prepayment meters per month and is striving to meet the growing and changingmarket demands and to minimize capital expenditure. The workshop is housed in largepremises and geared to cope with high volumes of meter tests and calibrations. There willbe significant upgrades in the near future with the possible acquisition and installation ofnew and advanced meter testing equipment. Quality systems are constantly being enhancedto improve and maintain highest levels of efficiency and accuracy.
CHALLENGES� The filling in of technical posts continues to be a hurdle for the current year and the year
to come.� A restructure of the Meter Engineering Branch will be considered and priority will given
to motivation and training of staff.
FUTURE PLANS� The focus for the forthcoming year will be the investigation into new technologies such
as smart metering for residential customers and a new multi-vendor advance meterreading (AMR) system and specifications for a new single phase and three phases TestBench. The AMR investigation will enable the remote reading, disconnections andreconnections of meters for residential customers and allow multiple meter vendors.
� Smart metering will also enable the limitation of customers' loads which can be used tomitigate unwanted future load shedding procedures.
CUSTOMER SERVICES BRANCHThis branch is responsible for the processing of all applications for supply, registration ofcustomers for billing purposes, meter reading services, auditing of meter readings, resolvingaccount queries/disputes, technical advisory service and the cashiering facilities at variouselectricity customer services shops.
HIGHLIGHTS AND LOWLIGHTSRMS (Revenue Management System)The “RMS System” is still being finalised and senior Customer Services administration staffmembers are still assisting with the finalisation to ensure that all Electricity's concerns areaddressed. There have been delays in the transition between Coins and RMS project. Dueto the delays, temporary staff members are being employed in permanent positions in otherdepartments and new staff has to be trained.
NEW APPLICATIONSThe ongoing provision of “RDP” Housing has seen our administration staff efficientlyprocessing applications to ensure the timeous “switch on” of electricity for these houses.This is only possible with the close co-operation between the Housing Department, CustomerServices, Finance Department and the Depots and will be ongoing in this new financial yearwith new improved methods of communicating with Housing.
METER READINGA new pilot project has been initiated for meter reading. This pilot project will investigatethe market for new meter reading hand-held units due to the current high costs ofmaintenance and replacement of the present units. A local manufacturer is being sourced.
IMPROVING SECURITYIn view of the high crime rate, Customer Services Centres are always improving securityfor both their staff and customers. The Rotunda Customer Services Centre at HQ has beenburgled three times in the last financial year. It will now have burglar guards installed onthe outside and the parking lot will be improved with new boom security and guards in thenew financial year.
NEW AND EXCITING TECHNOLOGIES AND PROJECTSAccommodationNew premises are needed for the Northern and South Western Region. Northern arecurrently occupying Mallacca Road depot and have been given notice to relocate.Besters Customers Services Centre is investigating the addition of a second floor to theirbuilding to accommodate all North Western staff, which is in-progress with the Architecturaldepartment. A new Northern Customer Services Centre has been secured at Gateway.
SMS TECHNOLOGYThis is currently being investigated to capture meter readings by consumers via cell phones
WEB PAGE DESIGNThis is being investigated to capture on-line applications, account queries, meter readingcapture, token purchases and compliance information to be displayed.
ROTUNDA DISPLAYSThese large screens will be placed at entrance of Rotunda displaying all necessary informationto consumers regarding applications, queries and tariffs. Once this system is optimized, itwill be installed in all Customer Service Centers.
QUEUING SYSTEM AND CUSTOMER FLOW MANAGEMENT SYSTEMThere is a definite need for this system to be installed in all customer service areas. Currentlywe are investigating the local market, such as systems at SARS.
CONTACT CENTRE BRANCHThe Contact Centre provides a fault reporting service on a 24-hour, seven-days-a weekbasis. The Contact Centre is equipped to log faults and forward to the relevant Branchesfor corrective action to be implemented. The Contact Centre deals with all consumercategories, reporting a wide range of faults. Typical faults include:
� Loss of electricity supply� Metering faults� Street light failure� Poor quality of supply� Cable theft
CHALLENGESIllegal connections and cable theft make at least 30 % of the calls that we take per month.Electricity's bylaws are currently being amended to assist with the prosecution process sothat those that are guilty of illegal connection and cable theft get a reasonable punishment.
ACHIEVEMENTS AND AWARDSWe opened sms line where consumers can send us their meter readings as well as allother queries that they might have. We have reduced number of voice calls by at least1 500 per month.
FUTURE PLANSWe have proposed a fully multi media contact centre solution that will not only enable usto deal with voice calls but with all the latest media functions, including Facebook, Twitter,WhatsApp, Mxit as well as faxes. We plan to have staff managing this system 24/7 toallow us to respond to our customer queries in real time for all types of media communication.
The Commercial Departments of Finance, Information Communication Technology, Productivity and Business Process
Engineering, Supply Chain Management, Business Risk, Administration and Transport play a vital support role to eThekwini
Electricity. They also participate in numerous other Council projects/committees. Within the staffing constraints currently
experienced they strive to provide effective logistical support to the technical operations. A key feature of these departments
is to ensure that throughout, legislative practices, controls, policies and procedures are complied with.
In addition to the onerous Local Government Legislative and governance controls we also have to comply with, the National
Electricity Regulators (NERSA) has stringent requirements pertaining to reporting as a ring-fenced Business Unit. NERSA’s
Framework for Economic Regulation is complex and is presenting significant compliance challenges going forward.
Ensures that legislative
policies and procedures
are adhered to
Senior Manager:Information &
ADMINISTRATION BRANCHThe Administration Branch covers three key areas of the Department: Administration,Buildings, and Transport.
The Administration Branch is responsible for providing an efficient and effective DocumentManagement System, and operates within the parameters of an approved GovernmentalArchival System. With the increased use of electronic media, meeting the requirementsof the Archival Act, is a major challenge. The exploration of an Electronic DocumentManagement System is currently being undertaken.
Administrates the PABX and Telephone Management System providing various telephonereports to Senior Personnel for the purposes of monitoring telephone usage, customerliaison, document (correspondence) referencing, word processing of letters, reports, contractdocuments and transcribing of meetings, disciplines/enquiries etc. and the processing ofdocuments for micro-filming of electricity application forms.
FLEET DIVISIONThe Fleet Division is responsible for the acquisitions, maintenance, and disposal of vehicles.The Current Fleet size is 1 359, made up of Cranes, Aerial Platforms, Various Trucks,Bakkies, Cars, Generators, Trailers and Compressors. Majority of the fleet, are speciallymodified to suit the work activities undertaken by staff. The major challenges experienced,are the changes in legislation, and the period of time required to complete modificationsprior to a vehicle/plant being operational. By improving vehicle design and the standardisationof modifications of common categories, the time taken to modify a vehicle has been largelyreduced.
BUILDING MAINTENANCE DIVISIONThe Building Maintenance Division is responsible for general building maintenance, security,and the upkeep of the gardens/grounds at the Electricity Springfield Complex, NetworkControl Complex, Training Centre and HQ Complexes.
Due to the rapid expansion of new recruits, the provision of office accommodation andparking areas is a major challenge. Various interventions are being implemented viaacquisition of buildings, restructuring of existing office space, leasing of office space, anderection of new buildings.
INFORMATION TECHNOLOGY BRANCHThe 2012/13 year has been another busy and challenging year for the I.C.T department.The number of new initiatives, including Smart Metering, and the current upgrade ofeThekwini Electricity's enterprise asset management system, which is a strategic projectand its success paramount, has kept al l resources in ICT ful ly uti l ised.
Key internal focus areas for the department in this period however, was to continue tocapacitate the department with new resources and skills, and improve on our processesand procedures. There has been good progress in the recruitment plan in that a numberof Support Officer and System Administrator posts have been filled whilst numerous keyposts in ICT are in an advanced stage of recruitment.
The non-appointments in the outstanding posts can largely be attributed to unavailabilityof suitably qualified and experienced applicants, resulting in the re-advertising of these postsrepeatedly.
FACILITIES DIVISIONAs our Information Systems are being implemented and updated on an ongoing basis, theinfrastructure on which these systems rely, require constant upgrade or completemetamorphosis in alignment with best practices and the COBIT framework for good ICTgovernance. The imminent upgrade of eThekwini Electricity's Enterprise Asset ManagementSystem (Ellipse) at eThekwini Electricity, with its new system architecture, required significantinvestment in new hardware and software.
CHALLENGESElectricity recognized the need for a clear ICT Strategy and comprehensive SystemsArchitecture, and was to engage a service provider that specialized in the facilitation anddevelopment of Enterprise ICT Strategies, this unfortunately, was not achieved and resultedin difficulties in the forward planning for ICT.
The Facilities Division still suffers from human resource constraints however, the DataCentre Operations Manager post has essentially been filled, as we are awaiting finalauthorisation for the appointment of an incumbent. It will be a key focus and deliverablefor the Data Centre Operations Manager to expedite the filling of the vacant posts in thisBranch.
Continued improvements in the governance of ICT at Electricity have been achieved withongoing improvements being made in Change Control Processes and the monitoring andmanagement of system changes. The implementation of Sentinel has resulted in compliancewith the Auditor Generals recommendations from the previous year. In accordance withthe Auditor Generals Recommendations, ICT embarked on the development of a temporaryDisaster Recovery Site at Springfield Depot in 2012 but has unfortunately not received thenecessary approval of the Tender Specification for this. This project is also necessary toaddress the ongoing power related issues at Springfield Depot that have been responsiblefor regular downtime and service disruption. The new DR site was to eliminate the needfor the previously “out-sourced” hosted DR from HP, which was expensive. As a temporarymeasure, a reduced DR was achieved at the Corporate IS DR site in Scott Rd. This remainsa concern and a comprehensive DR Plan is in the planning process for hosting in the newlybuilt site in Westville.
DEVELOPMENT DIVISIONThe Development Division in ICT has had another very productive year with key projectssuch as the Ellipse upgrade, Meter Management Improvement Project, RMS and thePrepayment system requiring significant effort. In addition to the numerous projects thedevelopment team are involved in, ad-hoc requests for system enhancements, reports andnew systems integration have been ongoing.
Whilst systems development has largely been done by external contractors, the appointmentof a permanent Systems Developer has enabled ICT to replace the legacy Productivity/BonusIncentive Scheme with an in-house developed system.
SUPPORTExcellent progress made in the recruitment of ICT Support Officer's in 2011/12 hasresulted in continued improvements in the quality of service to the end user. Unfortunatelywe have seen a number of resignations in the Support division.The continued use of utilitiessuch as Zen Works Remote Control and the standardization of the Desktop client has alsocontinued to improve the end user service levels, by reducing the resolution time for mostcategories of support incidents.
The filling of the three vacant ICT Service Desk Operator posts this year has had a positiveeffect on the ICT Departments image and customer service satisfaction. Unfortunately wehave seen the resignation of one of the ICT Helpdesk Staff.
PROJECT OFFICEAs the hub of ICT, the Project Office has had another incredibly busy year in Project Managingnew and existing projects. The increase in the use of Vibe as a collaboration Tool and ProjectManagement & Document Management Tool by the business, has kept the Project OfficeResources busy with End User Training of Vibe and the ongoing administration of the VibeSystem and Workspaces. New workflows for Change Control and IDM have been implementedand further workflows for various ICT Processes have been initiated. The project Office hasalso been moved to new premises at Springfield Depot as ICT has outgrown the currentoffices at HQ.
The upgrade of the current Ellipse Enterprise Asset Management System (EAM) to thelatest version Ellipse 8 is nearing conclusion. Delays in the data conversion, as a result ofthe Vendor Conversion Utilities experiencing problems, have resulted in a new Ellipse 8 GoLive estimated for March / April 2014. Ellipse 8 is essentially a completely re-written systembased on a more modern technology stack and as such has provided a number of challenges.
NETWORKICT has made significant improvements in the data networks at Electricity. The upgrade ofall edge switches and core switches is complete. This has improved the management,availability, security and performance of the network and supports future businessrequirements such as Virtual Conferencing and Voice Over IP.
The introduction of both Vodacom and MTN APN's (Access Point Name) as an enterpriseMobile Communications Medium has seen intense growth and now supports Mobile servicessuch as E-Mail and Remote Desktop Access for authorized users, as well as solutionscurrently envisaged for eThekwini Electricity as part of the Ellipse Mobility Module i.e.:Inspections and Defects, Dispatch and Asset Inventory Survey. As security risks haveincreased exponentially with mobile devices attaching to the network, ICT have installed andconfigured security appliances to monitor and manage any potential security threat.
PREPAYMENTEThekwini Electricity has approximately 339 000 prepaid customers, currently supportedby our on-line pre-payment vending system. Sales Revenue, of approximately R765 millionper annum, is generated from 120 Credit Dispensing Units throughout the eThekwiniElectricity area of supply. Most of these (CDU's) are installed at private vending Agents, thatsell tokens on our behalf, and a few are installed at Electricity Customer Service Centers.Since the introduction of our first Third Party “Super” Vendor, Cigicell (Pty) Ltd, eThekwiniElectricity has been able to increase the number of Points of Sale (POS) by almost 500.The increased footprint significantly improves the accessibility of the Prepayment VendingPoint of Sale and hence making it more convenient for our customer. Over and above theregular slip type vouchers that are available, eThekwini Electricity customers are now ableto recharge their Prepaid Electricity online, from the comfort of their own homes, by simplypaying with their debit/credit cards or EFT (Electronic funds transfer). Customers are alsoable to purchase electricity via the web, certain mobile applications or SMS and customersusing Mobile applications are now able to view electricity saving tips, statistics of theirconsumption and receive SMS alerts when their electricity level is low, at no additional cost.
In summary, ICT has had an incredibly busy and productive year, despite the severe lack ofinternal human resources.
FINANCE BRANCHThe Finance Branch is responsible for the financial control over all activities of the Department.This includes, inter alia, the management, monitoring and control of revenue, operatingexpenditure, capital expenditure, insurance claims, financial systems, procedures and theprovision of advice and guidance on matters related to finance to all personnel. TheDepartment's annual and medium term budgets, annual financial statements and monthlymanagement reports are prepared by the Finance Branch.
The Branch also monitors compliance with statutory and internal regulations.In addition, the annual financial statements for the 2012/13 year and the multiyear budgetsfor the 2013/2014 year onwards were prepared and approved within stipulated deadlines.
During the year under review, the Finance Branch continued to contribute to several projectsin the Department, namely, the Outage Management System (OMS), the RevenueManagement System (RMS) and the Asset Management System (AMS). Phase two of theAMS implementation, which relates to MV/LV, is now at the advance stage and is expectedto be completed in the last quarter of the 2012/13 financial year.
Finance is also playing an active role in the implementation and rollout of Ellipse 8 systemimplementation which is expected to go live by the end of the 2013/14 financial year.
The Regulatory Reporting Manuals (RRM) project required by the National Energy Regulatorof South Africa (NERSA) is 90 % complete. Final review or adjustments are awaited fromthe Regulator, with the project expected to be finalised by October end 2013. With theaudit and successful completion of the 2012/13 Annual Financial Statements compilation,Management would like to recognise the dedication and enthusiasm displayed by the staff.
PROCUREMENT BRANCHThe Procurement Branch of Electricity provides a service for all Stock, Service Orders NonStock and Emergency Orders for the whole of Electricity and their depots. One of the Policieswhich are adopted by the Purchasing Department is ensuring that the strategy and valueDelivery are continually kept under Review in line with changes in Technology and SupplyMarkets. Springfield Complex Buying Office Provides a hand on Procurement Service to theMechanical workshop, Electric Workshops, Transmission Cables, Substation, Central Depotand the Transport Section. Purchases and Services are Unique and Specialized.The Challenge for the Forthcoming Year is keeping in line with the Pure Eco Environment,by recycling and re-use to initiate cost saving by viewing the total life cycle of products whichshould benefit cost plus have an environment friendly impact.

BID ADMINISTRATIONThe Bid Administration Section administered 121 contracts for the supply of goods andservices of which 21 were labour contracts.
The theft of cable was a huge challenge in the last financial year. We installed decals onall the contractors' vehicles and changed their overalls to red to ensure that they wereeasily identifiable. Twelve apprentice electricians qualified as electricians. Thirteen appealswere received by the Appeals Committee and were successfully defended.
STORES DIVISIONStore's is a division within the Finance & Administration Department of Electricity serviceunit that forms part of the Materials/Buying division.
We operate 22 Stores located throughout the distribution area and stock 3 500 items.In addition to the warehousing and issuing of stock items, the Stores are responsible forreceiving of all direct (outside) purchases.
HIGHLIGHTS� Stock discrepancies have been reduced, in comparison with previous terms.� New methods and processes in terms of stock control has yielded lesser shrinkage and stock losses.� Recruitment of more women into the Stores environment has added energy and productivity
to the work ethic.� Scanning systems introduced at Meter Stores to capture individual meter details, for easier tracking of meters & providing more quality information to energy control.� The installation of new computers systems on each floor of Main warehouse stores. This
has improved service delivery and stock control, where storekeepers on each floor can review stock levels and perform random stock counts.
LOWLIGHTS� At the beginning of this review period i.e. July 2012, low staff morale, together with higher
than expected stock discrepancies were noted.
FUTURE PLANS� To improve on our Stock turn rates on previous years.� To improve on our customer services at, & service levels at Stores, on previous years.� To train & empower more staff members, in order to improve productivity & skills.� To acquire more reliable vehicles/equipment example, a new forklift for Stores, to improve
BUSINESS RISK BRANCHThe Business Risk Control Branch comprises of the Risk and Compliance Management,Investigations and Network Theft Division.
The Risk and Compliance Management Division is responsible for the identification,assessment and mitigation of risks within eThekwini Electricity.
Compliance to procedures and policies is assessed for different Departments within theUnit.
The Investigations Division is responsible for the investigation of incidents relating tomaladministration within the Unit whilst the Network Theft Section is responsible for theidentification, investigation and mitigation of infrastructure theft on eThekwini Electricity'sreticulation network.
Cable theft and theft from substations have spiraled out of control during the year. Specialoperations were planned in hot spot areas with the assistance of SAPS. Two syndicatescomprising of five members each were arrested during these tactical operations. Patrolsat substations also resulted in several arrests. Criminal cases tried at court have seenthieves getting sentences between 3 months and 3 years.
A new tender has been awarded which will ensure 250 distributor substations being installedwith pepper gas systems as an anti-theft device.
A series of risk workshops was conducted during the year where the Unit's strategic andoperational risks were identified and assessed. Together with the relevant stakeholders,risk mitigation strategies were designed. The workshop also led to the development of theUnit's risk register which is considered a fundamental tool in the effective management ofthe business. Regular monitoring of progress on the various tasks allocated to task ownershas been conducted and it is envisaged that completion of the various tasks would meettheir desired target dates and consequently support the mitigation strategies.
During the financial year 2012/13, several investigations into maladministration within theorganization were conducted resulting in civil and criminal proceedings being institutedagainst the alleged perpetrators and recoveries of the losses.
FUTURE PLANSIn the ensuing year, we hope to be one of the drivers in convincing law makers into adoptinga more serious approach to incidents of copper theft. Should this be successful, we envisagethat with the implementation of new/amended legislation, harsher sentences would bemeted out to perpetrators found guilty of copper theft. It is also our aim to conduct an earlyidentification process of the Unit's future potential risks with a view to alerting managementtimeously in order that that sufficient time is available for the development and implementationof mitigation strategies. We will support management in their drive to adopt a zero toleranceapproach to maladministration within the organization. Hence, we will continue to pursueinvestigations and recommend action we deem necessary and which we consider to be inthe best interests of the Electricity Unit.
The Human Resource Department is responsible for providing guidance and support to the employees of eThekwini
Electricity Unit. HR Staff are involved in addressing issues which impact Human Resource management for the Unit
as a whole, through coordination of policy issues and involvement in labor relations activities.

21. LOSS IN ELECTRICITY DISTRIBUTIONEstimated Electricity losses 667 412 169 kWh (2012: 664 796 777 kWh) occured during theyear under review which resulted in revenue losses to the municipality. These estimated electricitylosses amounted to R396 million (2012: R364m)
The norm for electricity losses ranges from 5.6% to 12%. The loss incurred by the municipalityis 5.85% (2012: 5.8%) and is due to a combination of transmission/distribution losses andlosses due to illegal connections. In comparison to other Metro’s, eThekwini Municipality maintainsits losses at a lower end of the norm.
Transmission losses are inevitable, however, the following interventions have been implemented:
� OPTIMAL NETWORK CONFIGURATIONThe Planning and Design engineers ensure that all network additions are implemented withcorrect equipment ratings and configuration so as to minimize losses.
� EFFECTIVE MAINTENANCE ON NETWORKThe unit has adopted a comprehensive maintenance schedule to promote the reliability of thenetwork as well as enhance the efficiency of the network.
� EFFICIENT NETWORK LOADINGPower flow into the network is carefully monitored on a 24 hour basis and the correct, mostefficient electrical loading configuration is adopted
Illegal electricity connections are a major contribution factor to non-technical losses. Thefollowing interventions have been implemented to curb illegal connections:
� AREA SWEEPSThe Revenue Protection teams continuously investigate high theft area’s to remove all illegalconnections.
� EMPLOYMENT OF SECURITY INTELLIGENCE TEAMSPrivate investigators are deployed to site to try and gather evidence to apprehend suspects.
� INSTALLATION OF ANTI-THEFT TECHNOLOGIES AT SUBSTATIONSThe employment of this technology deters intruders from entering into substations and carrying out illegal connections.
� THEFT HOTLINEA 24 hour hotline has been set up to report acts of theft and illegal connections - Once a
suspicious activity is reported, security will be despatched immediately to the affected site.
