33United Power System of Russia in BriefUnited Power System of Russia in Brief

One of the largest power systems in the world (vs. US and UCTE)On-going restructuring/unbundling: from vertically integrated monopoly to liberalized systemGeographical size creates a number of particularities:

Electric power transmisson over very large distancesUltra-high voltage and high voltage linesEmergency automation

High degree of interdependence and cooperation within IPS/UPS due to a former single USSR power systemSystem control in Russia is deigned based on centralized dispatch but IPS/UPS synchronous zone is already using decentralized dispatch

44Facts and FiguresFacts and Figures

Total generation capacity 206,200 MW

Electricity generation 875.1 Billion kWh

Total length of 110-750 kV transmission lines 450 335 Km

Power plants, including

590

Thermal 319

Hydro 87

55System Operator for UESR System Operator for UESR

Role of the SO:

• Control and Operation of the Unified Energy System of Russia

• Ensuring the reliability of the national power system and quality of electricity supply (no major power system incidents and improve power quality in the midst of system restructuring)

•Support for the implemenation and opertion of the competitive market

The largest mapboard in the world, from the Baltic Sea to the Pacific Ocean – 7000 km.

Reform of the dispatch control in Russia:Significant change in organizational structureChanges necessary due to development and implementation of power and ancillary

services markets

Reliability/quality:Increase of the quality of supply maintaining a high power system reliability – main

item: load/frequency control (modernization of primary, secondary regulators; ensuring necessary active power reserves quality and quantity)

Transition from the centralized planning and control of a single (ex-USSR) power system to a decentralized one – elaboration and implementation of common operation rules for all partners of the synchronous zone

Market Support:Ensure the necessary support to the market oriented reforms of electricity sector due

to a huge role of the System operator in competitive market infrastructure –Implementation of a modern SCADA/EMS system

Elaboration and implementation of balancing and ancillary services market Integration with UCTE: Feasibility study of the synchronous interconnection will be

jointly performed by UCTE and UPS/IPS TSO-s (ISO-s)

SCADA/EMS ImplementationScope of the Project and Current Status

All existing SCADA/EMS were designed by Russian companies. Although the system are still functioning according to specifications SO decided to replace the SCADA/EMS on all three hierarchical levels with modern state-of-the-art systems., including:

Central Dispatching System (CDU) in Moscow and 7 territorial systems (ODU’s)- Center, Northwest, Middle Volga, North Caucasus, Ural, Siberia, Far East. A supplier for these systems will be selected through international tender.55 regional systems will be supplied by domestic companies.

Current Status:Evaluation of Tenders for CDU and 7 ODUsImplementation of the 55 regional systems is well under way. Currently already xxx systems in operation

All systems shall be in operation by the end of 2007

99Reasons for ReplacementReasons for Replacement

Existing systems are closed to the end of its useful life cycleNew requirements for the support of the competitive Wholesale Energy Market in RussiaInterfacing with future automation systems of Federal Grid company and Trade System OperatorEfficient synchronous interconnection with UCTE and coordination with IPS’s of former USSR republics.

Economical benefit of the system: Net present value for CDU and 7 ODUs is estimated well above 500 MEuro, due to:

Increased reliability and quality of operational controlOptimal Maintenance SchedulingImproved Generation SchedulingReduced overall network losses

Turn Key project: All system databases, displays and network models shall be delivered and implemented by the supplier

CIM and GID ComplianceAdvance Generation Scheduling functionality Market support functions and market interfaces
