   *DSO can become a subject of settlement
Page 5
         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

     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

    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

Page 11
                        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

Page 12
            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

Page 13
      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)
