Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, whether his Department has identified the (a) location and (b) severity of capacity constraints in the energy distribution network.

Ofgem’s price control supports network reinforcement to enable Distribution Network Operators to increase network capacity where required. Ofgem has published analysis of current and future capacity constraints in its framework consultation for the next electricity distribution price control period, beginning in 2028.

Ofgem will also promote data sharing and digitisation across DNOs to improve network visibility and reduce constraints.

In 2026, National Energy System Operator will publish Regional Energy Strategic Plans (RESP). RESPs will support coordinated development of the distribution system and enable long-term investment in capacity to be made with confidence and ahead of need.
