The UK Government’s REMA programme, launched in 2022, aims to modernise the electricity market to support a decarbonised, cost-effective, and secure power system. This 2025 summer update outlines key decisions and the next steps in delivering a future-fit electricity market aligned with the UK’s clean energy ambitions.
Key Decisions
- Retention of a Single National Market: The government has decided to maintain a GB-wide wholesale electricity market, rejecting the proposal for zonal pricing. To ensure consistency and simplicity for investors and consumers.
- Ambitious Reform Package: A comprehensive set of reforms will be introduced to:
- Improve market efficiency.
- Enhance coordination and strategic planning of the electricity system.
- Support the transition to a renewables-based, flexible, and resilient grid.
- No Zonal Pricing: After extensive consultation, zonal pricing was deemed less effective in delivering value and certainty compared to a national model.
Strategic Objectives
- Clean Power by 2030: REMA is a cornerstone of the UK’s mission to become a clean energy superpower, targeting full decarbonisation of the power sector by 2030.
- Consumer Value and Security: The reforms aim to pass the benefits of renewable energy to consumers while ensuring energy security and affordability.
- Investor Confidence: By providing a stable and predictable market structure, the government seeks to attract long-term investment in clean energy infrastructure.
Next Steps
- Detailed Implementation Plans: Further details on the reform package and implementation timelines will be published later in 2025.
- Collaboration with Stakeholders: Continued engagement with Ofgem, the National Energy System Operator (NESO), and industry stakeholders will be critical to delivering the reforms.
