Review of Electricity Market Arrangements (REMA) consultation


Following the commitment set out in its British Energy Security Strategy, the government published a consultation on the Review of Electricity Market Arrangements (REMA), with the aim to ensure that the electricity market design is fit for the purpose of maintaining energy security and affordability for consumers as the electricity sector decarbonises.

The consultation set out a range of options for reform for all (non-retail) electricity markets, including the wholesale market, balancing mechanism and ancillary services, as well as policies that impact these, such as the evolution of and alternatives to the Contracts for Difference (CfD) scheme and the Capacity Market.

The document included a number of chapters that explore areas up for discussion including its overall approach to market reform and options for delivering a net zero wholesale market, capacity adequacy, and flexibility.

Following the consultation, which closed on 10 October 2022, the government published in March 2023 its summary of consultation responses and its updated policy position with regards to the options set out.

We recommend reading the consultation, and the consultation responses summary, and noting the possible options for reform.
