CONSTITUENCY BRIEFING · ENERGYMAP.APP
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.
