What is Burnham’s GB Grid plan and could it bring down energy bills?

Prime Minister Andy Burnham announced the creation of Great British Grid, a state-owned body designed to address Britain’s elevated energy costs and support economic growth through public investment in the electricity network. The initiative builds upon the Labour party’s manifesto commitment to establish Great British Energy, a state-owned renewable energy company. Burnham characterized the current situation as a cost crisis, noting that British households and businesses face some of Europe’s highest energy expenses and lack control over a system where prices are determined by distant markets.

Great British Grid will operate in partnership with private sector entities and network companies to increase competition, reduce costs, and accelerate grid connection timelines. The government-owned body will have approximately £4 billion available for investment, representing a portion of the anticipated £70 billion investment expected across five years. Beyond its direct investment capacity, the plan includes expanding rights for developers and businesses to construct their own infrastructure and connect projects to the grid. GB Grid will provide support and co-investment opportunities, enabling companies to compete with established network operators for transmission projects. The approach draws inspiration from Ireland’s model, which has reduced connection times by approximately 11 months through competitive tendering.

The proposal has garnered support from various stakeholders. Advocacy groups and industry observers have welcomed the initiative as a meaningful step toward addressing longstanding delays in grid connections. However, skeptics within the network industry have questioned whether competition alone can overcome systemic constraints related to supply chains, skilled labor availability, and planning processes.

Grid connection delays have become a significant obstacle to Britain’s renewable energy expansion. Connection queue times previously exceeded 15 years, though a two-year program to remove speculative applications has improved conditions. Network companies are projected to spend between £70 billion and £80 billion from 2026 through 2030, with potentially £89 billion required in the subsequent decade. These substantial expenditures, controlled by industry regulator Ofgem, are recovered through energy bills, contributing to rising consumer costs.
