No.115 of 650 · approved, not built MP: Jenny Riddell-Carpenter (Labour) England

Suffolk Coastal

Suffolk Coastal has 52 MW of clean power (all solar) approved and still not built: enough to supply a year's electricity to 19,000 homes. Britain's grid bottlenecks still add to bills here: about £92 a year per household, £3.9m across the constituency's 42,806 homes.

No big wind farm on the national grid is mapped to this constituency, so no switch-off payments show here in national data. Smaller wind farms on the local grid can still be paid to switch off — invisibly. The £ figure for this seat is a floor, not a zero.

52 MW
of clean power — all solar — approved and still not built, enough to supply a year's electricity to 19,000 homes. Approved at least two years ago; waiting on the grid, not on planning. That is 2.2× the renewable capacity actually running here.

£3.9m
is what the grid gap costs this constituency's 42,806 households in a year between them — £92 each, about 51 days of one home's electricity.
The £92 per household is a national figure — identical in every GB seat. Only the seat total varies, with the number of households · NESO · how we worked this out

What this page does not show

Smaller wind farms on the local grid are also switched off; national data does not show it, so the £ figure here is a floor, not a zero. Offshore wind is counted nationally, never per seat. The planning database can run a quarter behind reality.

Electricity does not travel from a particular project to particular houses. Everything generated goes into the national grid and everyone draws from that shared pool, so "enough for X homes" is a way of sizing the electricity — not a claim that these homes would be powered by this site. Battery storage is counted separately from generation: it moves power in time rather than making it.

Planning statuses come from the government's planning database (REPD), which records what was decided and when, but not why. Where a project was refused we say so and name the authority; for the reasons, look up the planning reference on that council's own register. How to check any figure on this page →
