What kind of markets are there and how do they work?
The value of electricity changes per hour depending on the current demand, weather forecast, outages, fuel and CO2 costs. Therefore, there are different electricity markets for different purposes. This page provides a broad overview of the different markets, who is active on them and in which timeframe.
Forward and Futures Market
On the forward and futures market, electricity is traded between four years and one month before delivery.
On the forward and futures market, electricity is traded between four years and one month before delivery. Forwards and futures are financial products, which are settled against spot market prices of future delivery periods. While futures are standardized contracts on power exchanges, forwards are traded bilaterally (over the counter) and are not standardized.
The forward and futures market is important for many large producers, large consumers, suppliers, Balance Responsible Parties (BRPs) or traders who trade power bilaterally to hedge electricity prices for a certain period of time. Hedging of prices gives these parties financial certainty that they will be able to purchase or sell a certain volume for a pre-agreed price.
If two parties want to conclude a deal across borders, they also need to acquire long-term cross-zonal transmission rights that are auctioned on the JAO platform.
On the day-ahead market, participants can sell and buy electricity in a pan-European auction for the 24h of the next day in (hourly) blocks.
On the day-ahead market, participants can sell and buy electricity in a pan-European auction for the 24h of the next day in (hourly) blocks. The day-ahead market is cleared at 12:00 o’clock noon each day of the year. At this time, the intersection of demand and quantity offered determines the electricity price and volume for each hour. This price is then either paid or received by all market participants who were successful in the auction.
Because the day-ahead market is organized short before delivery and has a single clearing price (per hour), it best reflects the value of electricity during different hours. The clearing price of the day-ahead market is therefore often referred to as “the electricity price”. The price is determined per bidding zone, which in Europe mostly corresponds to the borders of a country.
Through the intraday market, buyers and sellers can adjust their order volumes in line with better demand or renewable feed-in forecasts or unexpected power plant outages.
After the day-ahead market is cleared, the intraday market opens. Through the intraday market, buyers and sellers can adjust their order volumes in line with better demand or renewable feed-in forecasts or unexpected power plant outages. On the intraday market it is possible to trade power continuously in quarter-hourly, one hour or even longer intervals. As soon as a buy bid matches a sell bid a trade is concluded. A deal needs to be completed at least 5 minutes before delivery.
The platform for day-ahead and intraday trade is the spot market. There are multiple different spot exchanges for electricity in Europe, such as EPEX or NordPool. While they share the same trading platform, day-ahead and intraday market have different price setting procedures. Day-ahead trades are subject to a market clearing principle, where the last accepted bid sets the price for all transactions. Prices in intraday trading are set via the pay-as-bid principle. It means that the trade deal is completed as soon as a sell bid is accepted by a buyer.
In contrast to the long-term market for bilateral trades between individual consumers, producers or third parties, the day-ahead and Intraday markets are only accessible for Balance Responsible Parties (BRPs).
