Elektrilevi Network

Key drivers: regulationsElectricity market is opened for all customers since 1. January 201381% from all connections do have direct contract with electricity seller.

Estonia’s legislation is in accordance with the 2020 goal which states that all electricity meters must be replaced with smart meters by January 2017.

Fulfilment in two stages› Metering Points above 63A must have smart meter from 1. January 2013› Metering Points up to 63A must have smart meter from 1. January 2017

Legislation regarding metering were put in place July 2010

Key drivers/KPI benefits for DSOAsset base for electricity meters was old, 44% from total meters went off from

verification 2012-2016. Investments and re-verification was needed.

Reduction of losses, 2010 – 6,12% 2015 actual – 4,75%. Expected level for 2018 was 4,85%.

Project scopePrime Contractor› Responsibility for turn-key Project execution (625 000 MP-s) › Coordination between all parties: Elektrilevi, Solution provider,

Meter HW provider, installers etc.

Rollout Management› Priority setting and follow-up on installation progress› End-customer communication (on-site and call center)

Integration of AMR system into Elektrilevi IT landscape› IT architecture solution design and implementation› Responsibility for all integrations and IT developments

SLA level and Meter warranty

Mass rollout overview› Rollout duration 2013-2016 (Pilot rollout Q4 2012 - Q1 2013) › Rollout execution (during peak times ca 100 installers)› Average daily installation volume – 600 - 800 meters› Expiring meters - 44% of total meters had fixed installation Quarters as

requirement in Legislation (pictures below show rollout happening all over the country at the same time)

› Mass rollout - replacement of meters per full transformer areas

Field installation› Critical prerequisite for field installations is the planning

› What, when and where needs to be installed (example pictures) › Educate the logistics people to ensure smooth deliveries› Maintain sufficient buffer stock of field equipment› Training and tight control on the installers to ensure quality› Notifying end-customers in time is crucial to ensure access to meters

› Lot’s of Estonian meters are installed inside apartments› Central management system is needed for electronically follow-up the

chain from ordering to tracking of installed meters

PROJECT MANAGEMENT

System operationSystem operation covers two key domains:› IT solution administration

› AMR, Work Order Management, › Monitoring, Ticketing...

› Meter and Metering Data management (back-office and field activities)› Missing metering data handling› Faulty device (meters, DC) handling› Metering data analytics (events/alarms, abnormalities in metering

values)› Device configuration management

Communication in ProgramGeneral communication - Elektrilevi› Why meter replacement is needed› How and in which sequence it is done› http://www.elektrilevi.ee/en/kauglugemine

Installation related end-customer communication - Ericsson› Required agreements to access end-customer premises› Clarifications and information sharing during installations› Call centre for general inquiries

Customer satisfaction ratings (on 5 point scale)Regular end-customer meter replacement satisfaction index (Target level is

4,2 – current index level is 4,7)

Core topics Things to be clarified before project start:

› High level – Clear understanding what, why and when must be achieved

› Balancing the expected performance/functionality and TCO

› Technology roadmap - is interoperability and/or mix of different technologies opportunity or problem

› Stakeholders engagement – Customers, regulators, market participants

› Public Opinion – clear strategy for all customer segments

› Emergency rules – be prepared for accidents in all processes and levels
