Electricity Markets

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.

Our Whole Energy Market Strategy team was established in early 2024 to develop an independent view of cross vector market interactions, providing recommended solutions to tackling challenges, conflicts and inefficiencies to facilitate net zero.

Early Competition is a competitive process to select a bidder a solution or a specific need on GB's electricity transmission system. The process begins ‘early’, prior to the detailed design, surveying and consenting phases of solution development.

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.

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.

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.

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.
