CONSTITUENCY BRIEFING · ENERGYMAP.APP

Spelthorne has no significant clean power approved and waiting to be built, and none running. Britain's grid bottlenecks still add to bills here: about £92 a year per household, £3.8m across the constituency's 41,805 homes.
Ranks 569 of 650 for clean power approved and not built.
