Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what estimate he has made of the number of properties in Wales that are unable to generate their own electricity due to capacity constraints in the electricity distribution network.

The Department does not hold data on this. For generation of 3.68kW or less a property owner only has to notify the distribution network operator (DNO) post-installation. For larger installations the DNO will assess the impact of the proposed generation on the network, and either allow it to connect immediately or provide a connection date, and any costs.
