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.

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.
