The EPEX Spot Intraday Market is a central component of European electricity trading and is operated by EPEX Spot, one of Europe’s leading power exchanges. This market enables participants to trade electricity in near real-time, thus reacting to fluctuations in electricity demand and supply at short notice. The intraday market complements the day-ahead market, where spot market prices are set for the next day, and plays a central role in fine-tuning the electricity supply.
Introduction to the EPEX Spot Intraday Market
The EPEX Spot Intraday Market is a flexible trading platform for short-term electricity trading and an essential component of the European power exchange. It enables participants to react to short-term fluctuations in electricity supply and demand. This flexibility is particularly relevant with regard to renewable energies, which are weather-dependent and therefore require short-term adjustments in the electricity grid. The platform operates in parallel with the day-ahead markets, where spot market prices are set for the next day.
Functioning of the EPEX Spot Intraday Market
Intraday trading differs from the day-ahead market through its continuous trading. While prices on the day-ahead market are determined by auctions, intraday trading is based on constant pricing, which allows participants to buy and sell electricity in short periods such as hours or 15-minute blocks. This allows for fine-tuning, which is particularly useful when unforeseen events such as weather changes occur.
Participants and their roles
Various players participate in the EPEX Spot Intraday Market:
- Electricity producers: These players adjust their production to short-term fluctuations on the electricity markets.
- Energy traders: They use the intraday market to realize short-term profit opportunities or to optimize their energy procurement.
- Transmission system operators (TSOs): They access the intraday market to stabilize the electricity grid but do not act as direct participants. They can use the market to procure system balancing energy.
- Industry and large consumers: These players can optimize their energy consumption based on short-term price developments on the spot market.
Trading products and trading hours
The intraday market of EPEX Spot offers flexible trading products such as 15-minute blocks and hourly contracts. These enable participants to adjust their positions shortly before physical delivery. Trading begins immediately after the close of the day-ahead market and runs until shortly before electricity delivery. There are also occasional auctions that enable additional pricing and provide further liquidity.
