Reform of ESO’s ancillary service and balancing markets is crucial if we are to ensure that we can operate a zero carbon electricity system by 2025, and fully decarbonise by 2035. These reforms will also help to lower costs to end-consumers as they are designed to make our markets more efficient, accessible and liquid. 

We also understand that our ancillary services and balancing markets are an increasingly important revenue stream for market participants. It’s therefore imperative that we provide a clear view of how we see these markets developing.

This is the aim of the ESO Markets Roadmap. Here, we outline what we are doing to reform ESO markets and why we are doing it; to give the market the ability to build investment cases and all stakeholders the confidence that we are making the right design decisions.

Markets Roadmap

The roadmap sets out our market design objectives, principles and plans to reform and evolve our markets.

It details our vision for response, reserve, thermal, voltage, stability, and restoration markets as well as the Balancing Mechanism.

Markets Design Assessment

To complement our Markets Roadmap for 2023, we are publishing alongside an assessment of the design of our markets. This has been conducted by an independent party, LCP Delta, using our own market design framework, to assess how we are faring against our market design objectives of efficient design, efficient dispatch and value for money.
