CONSTITUENCY BRIEFING · ENERGYMAP.APP
Portsmouth North
Portsmouth North has 12 MW of clean power (all solar) approved and still not built: enough to supply a year's electricity to 4,200 homes. Britain's grid bottlenecks still add to bills here: about £92 a year per household, £3.7m across the constituency's 40,736 homes.
Ranks 218 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
- 2 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.
