Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, by when does he plan to conclude the policy development phase of the Review of Electricity Market Arrangements.

As part of the REMA Summer Update on the 10^th of July 2025, we concluded the REMA policy development and published our decision to retain a single national, GB-wide, wholesale market pricing regime and introduce an ambitious package of reforms to improve the efficiency of our power system. We will not implement zonal pricing.

We will set out how the reforms will be implemented in our Reformed National Pricing Delivery Plan later this year.
