Energy: Business

Asked by Gareth SnellLabour (Co-op)Department for Energy Security and Net ZeroTabled Answered 27 April 2026UIN 129202

The question

To ask the Secretary of State for Energy Security and Net Zero, what assessment he has made of the potential impact of the time taken for grid connection on the ability of businesses to lower energy costs through onsite generation.

Answered by Michael Shanks

Following Ofgem’s decision to increase the threshold for generation requiring a transmission impact assessment from 1MW to 5MW in England and Wales[1], it is now quicker and cheaper for businesses customers to install onsite generation. Ofgem’s Connections End‑to‑End Review will also improve customer service and reduce connection times for such projects[2].
