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.

The rest of the briefing
- Every approval each project still needs, and which of them the public can see
- What building them would mean here — community payments, business rates and construction work
- Drafted parliamentary questions and letters, filled in with this seat's figures
- 3 story angles for local reporting
- A two-page PDF, and a newsroom edition with the references and who to call
Everything above needs no account, and neither does the full seat page, the method or this constituency's raw data. The account covers the packaged briefing and its PDF, and nothing else.
