Intraday Market

The intraday market opens after the day-ahead market has been cleared, providing a platform for continuous power trading closer to the time of delivery. It allows market participants to fine-tune their energy positions based on more accurate, short-term information.

Key Functions

The primary role of the intraday market is to enable buyers and sellers to react to unforeseen events and updated forecasts. Participants can adjust their commitments in response to:

  • Changes in demand forecasts.
  • Fluctuations in generation from intermittent renewable sources like wind and solar.
  • Unexpected power plant outages or other grid disturbances.

This flexibility is crucial for maintaining a stable balance between electricity supply and demand.

Trading and Pricing Mechanism

Trading on the intraday market is continuous and can be done for intervals as short as 15 minutes. A deal is finalized the moment a buyer's bid matches a seller's offer, and trading for a specific delivery period continues until a "gate closure" time, typically just 5 minutes before physical delivery.
