Requiring the use of half-hourly data for reconciliation
Consultation
We are consulting on proposed Code amendments to require participants to submit half-hourly data into the wholesale market’s reconciliation process, where this data is available. This will improve cost allocation, strengthen price signals and enhance incentives for demand-side flexibility. Consumers would be able to make more informed decisions about consuming or generating electricity.
We will consider all submissions before making a final decision, which we currently expect to publish in April 2026. If we decide to proceed with our proposed Code amendments they will come into effect in late 2026 to early 2027.
We welcome your feedback by 5pm, Friday 21 November.
