Caerfyrddin
Caerfyrddin has 7 MW of clean power (mostly onshore wind) approved and still not built: enough to supply a year's electricity to 6,300 homes. When the wires are too full to carry the power, Britain pays wind farms to switch off instead. No wind farm here is paid that way — almost all of it goes to wind farms in Scotland. That cost is shared across every bill in Britain, so households here pay for it too: about £92 a year per household, £3.8m across the constituency's 40,938 homes. There is also 102 MW of wind running here on the local network. If that gets switched off, no national record shows it.
Ranks 244 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.
