Regulator aims to reduce backlog as some wind and solar schemes wait up to 15 years to get hooked up

The energy regulator is to introduce rules designed to kick out “zombie” wind and solar farms from the lengthy queue to connect to Great Britain’s electricity grid.

Ofgem hopes to speed up the process of hooking up new energy projects to the electricity network in the face of a backlog that is deterring investment and Britain’s attempts to switch to clean energy.
