Net zero grid upgrade costs spiralling out of control
EDF warns that the £70bn UK grid upgrade program may see costs triple due to inflation and delays, potentially increasing household energy bills. National Grid, Scottish Power, and SSE are involved in the project, which aims to support renewable energy and electric vehicle adoption. EDF and UK Networks Services suggest the current plan may be too costly and ambitious.
