Main Market Participants Share of generation Share of electricity supply (distribution) ČEZ 70 % 66 % EON 24 % PRE 10 % There exists one dominant generator with crucial share of generation and distribution as well.
Opening the Electricity Market in the Czech Republic • Wholesale electricity market completely opened • At present retail market is opening step by step • Today the electricity market is opened for all generators, traders and end consumers with continuous measurement and remote data transport • From 1.1.2005 the market is opened for all end consumers with exception of residential sector – implementation of load profiles
Model of Czech Electricity Market * * *DSO can become a subject of settlement
Model of Czech Electricity Market A subject of settlement (BRE) - at present 30 in the Czech Republic - is a market participant with responsibility (financial) for a deviation Deviation is a difference between actual (measured) and contracted (traded) volume of electricity
Deviation of a subject of settlement B R E O T E T S O / D S O Contracted volumes Actual volumes Deviations
Electricity Market Operator • Evaluates and settles deviations - every day for separate trading hours • Receives contracted (traded) hourly volumes from subjects of settlement in a day D – 1 (by 16:00) and real (measured) volumes for every hour in a day D + 1 (by 11:00) from TSO and DSOs • Deviations are evaluated by financial costs necessary for activation of ancillary services (reserve power) • Deviations are debeted to these subjects of settlement that caused deviations in separate trading hours
Further Activities of Electricity Market Operator • Organizes day – ahead market – by very traditional way • Organizes intra – day market; for separate trading hours; at present trading ends 3 hours before real time • Organizes balancing market – with single buyer only – TSO • Risk management of electricity market • Administration of changes of suppliers • In preparation: registration and settlement of „green electricity“ and CO2 emissions
Reconciliation curves 29 September 2004 – 23:00 – 24:00
Evaluation of Czech Electricity Market • The electricity market in the Czech Republic started in 2002 without notable problems • Trades of dominant generator ČEZ, a.s. have crucial importance for price – fixing process • Low liquidity of organized electricity market - day – ahead and intra – day markets about 1 % • Bilateral contracts represent predominated way of trading
What next? • It is impossible to increase liquidity of organized market and competition under existing conditions • Strategy for improvement of electricity market with existence of dominant players: - creation of a regional market - first step – preparation of infrastructure of the market
Regional Electricity Market • At present very popular idea • Solution is concentrating on solution of cross – boarder flows which is insufficient • The problem is more serious • the same rules for trading • the same rules for regulation • provision of reliability of electricity supply • Primarily it is a political problem
Infrastructure of Electricity Market • There have to exist an infrastructure independent on market players and dominant players especially - measurement and access to its results - settlement of deviations and their prices - administration of supplier (consumer) changes - trades in ancillary services - additional conditions that depend how the market was started (e.g. in the Czech Republic obligation for EMO to organize day – ahead market)
Conclusion More information about the Czech electricity market – even in English - is available on web sites of OTE www.ote-cr.cz including results of day - ahead market, intra – day market and balancing market and statistical data
