No.77 of 650 · approved, not built MP: Órfhlaith Begley (Sinn Féin) Northern Ireland

West Tyrone

West Tyrone has 84 MW of clean power (all onshore wind) approved and still not built: enough to supply a year's electricity to 74,000 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. Northern Ireland is on the all-Ireland grid, so Britain's grid bottlenecks do not reach bills here in the same way. There is also 493 MW of wind running here on the local network. If that gets switched off, no national record shows it.

Not visible
here
493 MW of wind is running in this constituency, but it sits on the local network rather than the national grid — so if it is paid to switch off, no national record shows it. That is why this seat has no figure here: not because nothing happens, but because nobody publishes it. The £ figure for this seat is a floor, not a zero.
how we worked this out
84 MW
of clean power — all onshore wind — approved and still not built, enough to supply a year's electricity to 74,000 homes — about as many homes as this constituency has. Approved at least two years ago; waiting on the grid, not on planning. That is 0.2× the renewable capacity actually running here.

grid
Northern Ireland is part of the all-Ireland Single Electricity Market, not the GB grid, so the GB grid-gap bill does not apply here.

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 →
