CONSTITUENCY BRIEFING · ENERGYMAP.APP
Southampton Itchen
Southampton Itchen 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, £4.3m across the constituency's 46,715 homes. A 50 MW battery was refused planning here in 2025; while discharging it could have supplied about 175,000 homes.
Ranks 569 of 650 for clean power approved and not built.
