CONSTITUENCY BRIEFING · ENERGYMAP.APP
Blaenau Gwent and Rhymney
Blaenau Gwent and Rhymney has 66 MW of clean power (onshore wind and solar) approved and still not built: enough to supply a year's electricity to 42,000 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, £3.9m across the constituency's 42,525 homes.
Ranks 101 of 650 for clean power approved and not built.
