Review of electricity market arrangements (REMA)
The purpose of the review of electricity market arrangements is to identify reforms needed to create a fair, affordable, secure, efficient system and maximise benefits of clean power for consumers.
REMA Summer Update: 10 July 2025
Following on from the REMA Autumn Update in December 2024, we are announcing a key update on REMA. Government has concluded that reforming the system while retaining a single national wholesale price is the best way to deliver a fair, affordable, secure, and efficient electricity system.
Register for a REMA Summer Update 2025 Webinar
We are hosting two briefing webinars to provide an overview of the REMA Summer Update, an update on the main elements of the reforms package, and an opportunity to ask officials questions about the REMA process and implementation. The webinars will take place on:
- Thursday 17 July 2025, 2pm to 3pm
- Wednesday 23 July 2025, 10am to 11am
You can register for either webinar via the REMA update briefing webinar registration form.
Next steps
We will publish a Reformed National Pricing Delivery Plan later this year, which will set out the next steps for government to work together with Ofgem, the National Energy System Operator and industry to delivery these reforms.
We will also publish the full REMA analysis later in 2025, including a cost benefit analysis of the different wholesale market reform options.
Development of the REMA programme
REMA was launched in the British Energy Security Strategy in April 2022, with an initial public consultation published in July 2022. This was followed by a second public consultation in March 2024 - see the REMA Consultations section.
Engagement with the REMA programme
Since taking office, this government has carried out ongoing engagement with the industry, consumer groups and wider stakeholders – and will continue to work closely with all parties as the proposed changes are developed. We will continue to do this through a range of forums, including:
- internal working groups with delivery partners
- external expert panels - independent external experts to impartially scrutinise and quality assure REMA policy development and analysis
- a Strategic Advisory Panel - industry experts offering high level strategic direction for the REMA programme
- an End User Challenge Panel – with organisations representing end users to provide advice and evidence on REMA policy development
We also hold bilateral meetings and attend events and conferences to provide updates on REMA.

REMA updates and consultations
The first REMA consultation (July 2022) set out the case for change, and potential solutions across a wide range of reform options.
The second public consultation (March 2024) narrowed down the number of reform options and sought further stakeholder views on specific proposals and on the short-list of remaining options.
