Aberafan Maesteg
Aberafan Maesteg was paid £470k last year to switch off its wind farms, because the wires south were full. That would cover every local household's electricity for 6.4 days. A further 37 MW of approved clean power (almost all onshore wind) is still waiting to be built here: enough to supply a year's electricity to 32,000 homes. A 100 MW battery approved at Rhydypandy Road, Morriston in 2025 would store power that is currently wasted; it has not been built.
Ranks 162 of 650 for clean power approved and not built; 17 of 19 among seats with visible switch-off payments.

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.
