Estimated output of Scotland's large power stations right now.

Pumped storage uses power to pump water uphill; that counts as demand and is not netted against the generation above.

Flow to England (boundary B6) FORECAST

Scottish demand is not published live as open data, so it isn't shown here. Day-ahead forecast from NESO, not measured flow. SCOTEX is NESO's constraint group closest to boundary B6 (our mapping).

All four bottlenecks: B4, north of Scotland, central belt ›

Wind turned down (curtailment) LIVE

—MW being turned down now
—GWh since midnight (UK)

When the wires south are full, NESO pays wind farms in Scotland to turn down and pays plants nearer to demand to turn up.

Wanted flow vs capacity FORECAST

Each bar is a bottleneck. The line marks what the wires can carry; the bar is what the market wants to send.
