Consultation

This consultation sought feedback on a proposal to collect and publish information on generators’ energy margins.

We want to regularly collect financial information from large generators to calculate energy margins to provide insights into generator profitability in various market conditions.

The data will help us to monitor competition in the wholesale electricity market, particularly during periods of scarcity.

Thanks to everyone who provided feedback.
