Mid and South Pembrokeshire

MP: Henry Tufnell (Labour) Wales Data to July 2026

Mid and South Pembrokeshire has 9.5 MW of clean power (all solar) approved and still not built: enough to supply a year's electricity to 3,400 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, £4.2m across the constituency's 45,486 homes.

Ranks 231 of 650 for clean power approved and not built.
