ICIS publishes European Daily Electricity Markets (EDEM) on every working day (in England and Wales) of the year. EDEM assesses and records prices and market activity on the liquid markets in Europe, including but not limited to:

  • UK
  • Germany
  • France
  • Czech Republic
  • Hungary
  • Poland
  • Romania
  • Serbia
  • Spain
  • The Netherlands
  • Italy
  • Turkey
  • Bulgaria
  • Greece

The financial value of electricity is established by two methods:

  1. Price Assessments. ICIS assesses the market closing prices for a range of European power hubs on the day of publication, and publishes a price range for each delivery period on a number of liquid markets. This is known as the BID-OFFER RANGE, representing the highest buyer’s bid and the lowest seller’s offer at the relevant close of each market.
  2. Indexation (Heren Index). Indices are published for a variety of delivery periods and delivery points. Each Heren Index is a transaction-based price, calculated using the volume-weighted average of eligible transactions (trades) for the relevant delivery period reliably reported to ICIS.
