Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, whether her Department has made an assessment of the potential impact of recoupling the GB and EU day-ahead electricity markets without recoupling the intraday markets on the competitiveness of wholesale electricity markets.

In 2021, HMG consulted on current arrangements for trading electricity on power exchanges in the GB wholesale electricity market and outlined proposals to support efficient cross-border trading. That consultation focused on day-ahead trading but also sought views on the intraday timeframe.

HMG’s consultation response outlined the intention to legislate to achieve a single GB clearing price in the day-ahead timeframe, subject to engagement with the UK-EU Specialised Committee on Energy, industry and stakeholders to ensure HMG is well placed to make a final decision on progressing legislation. HMG confirmed development of efficient arrangements in other timeframes should remain under review.
