Beyond 2030

• A network to enable the UK government to meet the sixth Carbon Budget. To deliver the required network by 2035, the actions in the Transmission Acceleration Action Plan are required.
• Creates the backbone needed to transfer power for and to future industry.
• 20,000 jobs will be created and sustained annually, with 90 percent of these benefits felt outside of London and the southeast.
• Facilitates the connection of a breadth of other low-carbon electricity generation, including Sizewell C and Hinkley Point nuclear power plants.
• Is a once in a generation expansion of Great Britain’s electricity grid. It proposes a network that has three times more undersea cabling than onshore infrastructure by 2035.

What are the next steps in the process?

Both industry stakeholders and Ofgem will review our recommendations. Industry will develop these recommendations further through a Detailed Network Design Phase. 

Depending on a recommendation’s maturity, this can involve testing alternative on and offshore solutions, further developing cable routing and technology choices.

We expect industry will engage extensively with communities on these options.

Improving our network development process

As we transition into the National Energy System Operator, we will continue strategic planning across other energy vectors and technologies publishing further plans in 2025 and 2026.
