Delivering a reliable, resilient, decarbonised electricity system in GB by 2035 will require action to enable infrastructure and
generation investment.

The UK Government has committed to decarbonise electricity supply by 2035, requiring a fundamental shift in the generation mix away from high-carbon, thermal generation to a combination of renewable and other low-carbon generation technologies.

Delivering on this commitment will require major new investment in renewable generation, flexible low-carbon technologies and critical infrastructure. On March 9, 2023, the Climate Change Committee (CCC) published a new report, Delivering a Reliable Decarbonised Power System, that investigates what a reliable, resilient, decarbonised electricity system may look like in 2035 and the steps required to achieve this.

The findings in this report were informed by a supporting study from AFRY Management Consulting, Net Zero Power and Hydrogen: Capacity Requirements for Flexibility. The study investigated the scale and range of flexibility options in a decarbonised electricity system to inform a set of tracking indicators for flexibility within the power and hydrogen sectors.
