SCOPE OF WORK

Avče Pumped Storage Plant is the first power plant of its kind in Slovenia and represents the largest investment in Slovenian energy sector at the moment. According to the project plan of the Investor Soške Elektrarne Nova Gorica d.o.o., the commissioning of the plant is foreseen for the end of year 2008.

The Avče PSP is located on the Soča River, approximately 24 km north of Nova Gorica and 2,3 km upstreams of Ajba dam. The Ajba reservoir serves for downstream HPP Plave I and II and also as lower reservoir of Avče PSP. The upper reservoir is located in a natural depression on the hilltop near to the village Kanalski vrh, with a reservoir confining a water volume of some 2,2 mio m3. A 700 m long headrace tunnel, running underneath the ridge of Avški Kuk, and 1,3 km long steel penstock connect the reservoir with the powerhouse, located on the left bank of the Soča River. The maximum head of 521 m and the installed discharge of 40 m3/s enable the maximum power of 185 MW in turbine mode. The maximum power in pump mode is 180 MW at discharge of 32 m3/s.

During the off-load hours, the power plant will operate in pump/motor mode consuming the energy for pumping the water into the upper reservoir. During the peak-load hours the accumulated water will be used for production of electrical energy. The planned yearly consumption and production amounts to 563 GWh and 426 GWh, respectively. In spite of higher consumption compared to production, the price difference will result in high profitability of the power plant.

Besides covering a significant part of the daily peak-load in the Slovenian power system, Avče PSP will also provide additional services, such as system reserve, frequency control and voltage control.

In the frame of Avče PSP project, the Consortium of Korona Power Engineering (Ljubljana) and COLENCO Power Engineering Ltd. (Baden, Switzerland) elaborated the following documentation:

2010

SCOPE OF WORKS Solar photovoltaic power plant Gut & Pet is a turnkey solution, which means that we took the whole project organization and realized it hand in hand with investor’s idea. In addition to building the PV power plant itself, we obtained all of the permits and approvals that are needed in the case of photovoltaic power plant connection to the public distribution network. We arranged all the necessary documentation for the investor and handed him the operating instructions. We have also provided a professional maintenance support for the power plant. Solar photovoltaic power plant Gut & Pet is grid connected and acts as a distributed energy PV source. All produced electrical energy is fed into the distribution system network. The main units of the system are:

Photovoltaic generator in form of polycrystalline silicon solar modules, metal supporting structure on the roofs of two manufacturing facilities, inverters, protective devices and switching components with wiring, control devices, monitoring site with electricity meter.

PV POWER PLANT DATA: INSTALLED POWER: 201.312 kWp MODULE TYPE: BISOL 233 Wp INVERTER TYPE: SMA Sunny Mini Central 11000 TL PLANNED YEARLY YIELD: 215 MWh OPERATION PRINCIPLE: The main component of PV power plant are photovoltaic modules, which are made of polycrystalline silicon cells. These are using photoelectric effect that converts solar energy into electricity. Photovoltaic generator (PV modules) feeds the power into the grid trough the inverter that converts DC voltage from the modules, into the AC voltage that is suitable for connection to the distribution network. Monitoring and controlling of the PV power plant operation also plays an important role in the system. Photovoltaic power plant system should therefore contain a central unit for data collection and control of the system operation. Other elements that are important for safe operation of the PV plant are surge protectors, fuses and main disconnector switch (which separates the plant from the grid), that are located in the main cubicle, which is also the link between the inverter and PV generator. Before the generated electricity is feed into the grid, its output must be measured. This is accomplished in the measuring site, which includes an electricity meter.

SCOPE OF WORK HSE Group, Holding of Slovenian Electrical Power Plants, is the operator of hydro power plants on three river chains, three major thermal power plants and one nuclear power plant, all located in Slovenia. One of HSE Group’s daughter companies is DEM, Slovenian Hydro Power Plants on the Drava river. HSE Group and DEM decided in 2005 to implement together a new DU CC with the functionalities fulfilling the needs of both companies. The investment was estimated for HSE Group to the value of 2 million euros and for DEM to the value of 1,3 million euros. The new DU CC was successfully put in operation in March 2007, it consists of the Group CC and of the River CC. The Group CC is responsible for managing the balance of the whole HSE group, planning of generation, realisation of operation, equalisation of deviations from the planed production levels and analysis of the whole generation of the balance group HSE, while at the same time maintaining focus on assuring reliable and optimal operation. The River CC is taking care for the optimum exploitation of water potentials of the river Drava. The Group and River CCs thus have different functionality, however they reside on the same IT and communication resources, while the data sets and views are strictly divided as per the needs of each utility. Furthermore, Group and River CCs are synchronised with each other and with the Austrian and Croatian CCs on the river Drava.

Complete implementation of the new DU CC was entrusted to a consortium of companies KORONA and Iskra Sistemi. New DU CC is built on a proven ABB Network Manager platform that includes communication, SCADA system, WEB SCADA, AGC (Automatic Generation Control), ProdPlan application (Production Planning) and UDW (Utility data Warehouse).

2006 - 2008

SCOPE OF WORK Lafarge Cement is building a new fuel gas desulphurisation (FGD) plant, which will be an extension to the cemetery plant LAFARGE Trbovlje. The commissioning of the plant is foreseen for the middle of year 2007. Carrier of the whole project is a company Austrian Energy and Environment, with KORONA as their local partner that had undertake the following works:

- electrical design, - measurements, - automation and - erection.

The electrical system as well as the process control system for the FGD plant will be integrated in the existing electrical distribution respectively in the existing plant control system. For this purpose and for operator comfort the same HMI surface and the same control hardware and software will be used. The FGD is designed on the basis of a limestone washing suspension, which is the most frequently used process around the world. The project focus is the reduction of operating costs by means of increased plant efficiency by means of flow mechanics calculations (computational fluid dynamics - CFD), as well as improvements in chemical SO2 absorption.

SCOPE OF WORK For better supervision of energy sources and energy consumers, as well as of related costs, in B&B Papirnica Vevce has been decided to establish an Energy Management System (EMS). EMS helps user at optimizing, arranging and managing of energy sources and consumers. Supplementary features are: alarming, archiving and report generating. The hardware configuration is based on three Siemens PLCs which reside on different locations: heating plant, 6 kV switchyard and hydro power plant Fuzine. The data from PLCs is collected and processed on the SCADA computer in the control room of heating plant. Software part of EMS consists of two main modules:

peak-demand-preventing module calculates energy demand in certain period of time and warns in case of exceeding the limit of maximum demand;

costs-calculating module calculates the costs of energy production and consumption. Optimizing, arranging and managing of the energy system is based on calculated costs.

Performed tasks are the following:

hardware supply, PLC programming, software programming on SCADA computer, documentation design, system testing and commissioning.

Connection with production management system is also expected in the future. By this the costs of energy consumption will be calculated in correlation with paper type and quantity.

Transformer owners have always been faced with the challenge of a given transformer optimizing the performance and increasing its useful life expectancy. Idea behind on-line monitoring is to continually and accurately diagnose the current condition and capability of the transformer, provide an alert “Just in Time” maintenance action when required. What are we looking for?

Automated meter reading (AMR) is a state-of-the-art technology that enables collection of data from geographically dispersed meters and other devices at customers’ premises. The data is collected at utility’s central location using either private or public telecommunications networks. It involves the following components: - electronic meters with register and communication interface unit, - concentrators inside transformer stations, - communication network or system to transfer the data from the meters to the utility’s

offices, - an AMR control center computers to receive, collect and manage this data - software to run the system and present the data to the utility's billing and other

information systems AMR presents a strong business case for distribution utilities. Namely, significant cost savings can be obtained by automating the monthly process of reading out the electricity meters with the on-line connection to the customer billing process. Such automation increases customer service, smoothens business operations, improves operational efficiencies and system reliability. AMR system can be even further expanded with connect/disconnect option (to enforce payment policies) and other functionalities, like reading of water and gas meters.

Meters with integrated

communication module

Concentrator inTransformer S/S

AMR Control CenterCommunication overpower lines

Private and/orpublic

network

The meter data is sent from a module inside your AMR enhanced meter to a substation on the existing power lines (DLC – Distribution Line Carrier). From the substation the data then travels to the corporate data center via communication lines, where the meter data is then integrated with customer information and billing systems, resulting in the production of a timely, accurate bill. Benefits of an AMR system:

- Reduction of Reading and Data Management Costs - Revenue Protection – better meter reading accuracy - Improves Customer Service - Maximizes Asset Management - Quickens Read-to-Bill Time - Improves Cash Flow from Shortened Floats - Reduces Bad Debt Due to Uncollectible accounts - More closely track shrinkage due to theft or loss - Balances Load with Power Purchases - Offers Variable Pricing Schemes - Real-Time Customer Load Information - Real-Time Pricing Support - Maximizes System Planning - Power Quality and Reliability - Outage Notification
