Standardised flexibility products

As part of the transition to the new standardised super-peak trading platform (Marex) and the introduction of super-peak market-making requirements on 31 July 2026, the Authority is reconsidering its approach to how it publishes data from the trading platform to ensure we protect commercially sensitive information.

We have paused publication of auction logs from the trading sessions while we consider our approach. We will provide an update as soon as we can. In the meantime, we will continue to publish the forward price curve and update it after each trading session.

The price and traded volume information for each contract is available on the flexibility hedge products dashboard.

Past auction logs

Past standardised flexibility product auction results, featuring an anonymised subset of the data, are published below.

The units of the 'Amount' column are megawatts while the 'Price' column reports dollars per megawatt-hour.

• Hold - New orders that are not live
• Submitted - New orders that are live
• Updated - Updated orders that are live
