Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what assessment he has made of the capacity of the National Grid to provide (a) timely and (b) adequate connections in the context of estimated trends in the level of adoption of rooftop solar installations on commercial properties.

Ofgem recently made it easier for smaller generation projects (under 5MW in England and Wales) to connect, by removing the requirement for a transmission network impact assessment [1]. For larger projects, the implementation of connections reform will prioritise connections that are ready and aligned with our clean power 2030 ambitions. Furthermore, the next Ofgem price control for electricity distribution (ED3, 2028-2033) will promote strategic network investment ahead of need, including through the introduction of Regional Energy Strategic Plans (RESPs). This will enable the timely connection of rooftop solar and other low carbon electricity generation across Great Britain.
