Across the ESO, we’re developing a range of market analysis, tools and recommendations to make sure GB’s energy transition is as fair and affordable as possible.

ESO Markets covers many meaningful disciplines, from preparing GB for a net zero future to broadening market access to present-day participants. Each year, our Markets team publishes several insightful reports, runs a range of innovative projects and hosts many interactive events to share their latest findings.

Learn more about the work underway in ESO Markets – including projects, publications, services and events – below.


Net Zero Market Reform

Our Net Zero Market Reform project is holistically examining the changes required to unlock renewables and secure savings for consumers. The report details our recommendations for a high-level package of reforms.


Pathfinder projects seek solutions to challenges in the electricity system as GB transitions to a zero-carbon future.

Early Competition Plan

Early competition – or the ability for a diverse range of market participants to take part in the market – is essential for innovation. It is encouraging new ways of working, aiming to seek the best solutions at a fair cost for consumers.

Stability Market Design

As more non-synchronous generation enters the system, the ESO needs to secure alternative sources of stability. We’re investigating the best option for an end-to-end Stability Market Design to enable an open, transparent and competitive market.

Future of Balancing Services

We aim to create balancing service markets that meet our changing system needs while ensuring that all technology types can compete on a level playing field. Visit our Future of Balancing Services webpage to find reports, updates and ways to get involved.


Markets Roadmap

The need to decarbonise the power sector is driving a fundamental shift in how stakeholders use and interact with the electricity system. The ESO’s annual Markets Roadmap sets out our ambitions, principles and process to transform GB’s markets.

Electricity Capacity Report

Our Electricity Market Reform (EMR) Modelling team measures the contribution that different technologies make to security of supply. Each year, they publish their modelling and provide annual recommendations in our Electricity Capacity Report.

Frequency Risk and Control Report

Published annually, this report includes an assessment of the magnitude, duration and likelihood of temporary deviations in system frequency, forecast impact and the cost of securing the system.



We procure a range of ancillary balancing services to balance demand and supply. With a range of market platforms, tools and data available, these services ensure the security and quality of electricity supply across Britain's transmission system.


We’re here to support those in the industry who want to propose changes, debate important issues and drive key outcomes. Visit our Codes page to learn about the different codes we administer, how to get involved and who to contact.


See our Charing webpage for guidance, charge summaries, open-access data and reports and information about how to get involved.

Electricity Market Reform (EMR)

The ESO oversees EMR services, which aim to deliver low-carbon energy supplies while maintaining security of supply and minimising consumer costs.


Markets Forum

Our regular Markets Forum event details the work underway across ESO Markets. Check out our latest webinars and the work we're undertaking to reform markets to support net zero for 2025 and beyond.
