Newport West and Islwyn

MP: Ruth Jones (Labour) Wales Data to July 2026

Newport West and Islwyn has 22 MW of renewables running, enough for 10,000 homes over a year, and nothing large waiting in the planning queue. 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, £4.0m across the constituency's 43,137 homes.

Ranks 528 of 650 for clean power approved and not built.
