Relevant data should

  • Be issued at the same time in a regional market
  • Be easily accessible
  • Be based on best estimates in good faith
  • Provide sufficient degree of confidence

► Data relevant to price formation and price modelling

► Data selected fwg a balanced assessment (need v. cost, confidentiality, aggregation level)

  • Transmission and access to interconnectors
  • Generation
  • Load
  • Balancing & reserve powers
  • Wholesale market

Market Transparency EURELECTRIC list Transmission and Access to Interconnectors (I)
  • Year-, Month-, Week- and Day-ahead forecast of available commercial capacity on borders
  • Planned maintenance of borderlines
  • Unplanned line outages

Market Transparency EURELECTRIC list Generation (II)
  • Installed generation capacity by fuel type
  • Ex ante available generation capacity by fuel type
    • information to be made available following a 2-phase-approach
  • Actual hourly aggregated generation by fuel type (ex post)
  • Unplanned loss of generation capacity
    • Ex post information by fuel type on price area level; 2-phase-approach
  • Water levels in hydro reservoirs
  • Further information on projected maintenance, mothballing, etc.

Market Transparency EURELECTRIC list Load (III)
  • Year-, Week- and Day-ahead aggregated forecast of load
  • Actual system load in MW/h
market transparency eurelectric list balancing and reserve power iv
Market Transparency EURELECTRIC list Balancing and reserve power (IV)
  • Price and volumes for balancing power
  • Aggregated capacity margin supply-demand
  • System balancing status

  • Progress towards harmonisation between regions
  •  Mini-Fora : natural vehicle to create momentum for levelling up transparency standards

  • 4 major German generators started to publish generation data via EEX-website based on EURELECTRIC proposal
    • Installed capacity
    • Daily available capacity
    • Net electricity generation (ex post)
  • Other German generators are following
  • Discussion of publication of further data ongoing

  • North Western European Market Parties Platform active in the pentalateral talks and representing EURELECTRIC in the Mini Fora
  • Proposes implementation of EURELECTRIC Paper in a two phase approach:
    • Creating a level playing field by publication of generation data according to the EEX definitions in all 5 countries by Q4 2006
    • Implementation of full EURELECTRIC proposal on generation data by Q2 2007 at the latest

  • Converging views on the overarching principles
  • More work needed on the details & definitions
  • Price area: relevant aggregation area
  • Ex ante generation schedule: little added value, conflicts with Competition Law to be explored

Thank you for your attention.
