What the project is for

The Review of Electricity Market Arrangements (REMA) Programme was set up in 2022 to consider how best to deliver a fair, affordable and secure power system. The review concluded in July 2025 with the Secretary of State taking the decision to retain a single national GB-wide wholesale market and introduce an ambitious package of reform to improve the efficiency of our future power system under a new programme called Reformed National Pricing (RNP). As such, the REMA Programme was officially closed in summer 2025 and offboarded as a GMPP programme at the end of the 2025/26 financial year.
