Great Britain Grid Status & Electricity Data

NESO (the National Energy System Operator) operates the electricity system across Great Britain (England, Scotland, and Wales). This is GridVigil's first grid tracked outside the United States, built entirely from NESO's own published data: national demand, generation by fuel type, carbon intensity, and cross-border interconnector flows with continental Europe and Ireland.

As of Aug 24, 2026, real grid metrics for Great Britain are shown below. GridVigil's Power Pressure Score is not yet calculated for this region.

Current data

• Current Great Britain electricity demand is 23.8 GW.
• The most recent peak was 29.3 GW.
• Operational generation margin (Aug 24, 2026 outlook): 61.24% of forecast peak demand.
• Grid carbon intensity: 123 gCO₂/kWh.
• Renewable generation (wind, solar, hydro): 11.6 GW.
• GridVigil Power Pressure Score is not yet calculated for Great Britain: the U.S. scoring thresholds aren't a defensible fit without region-specific calibration, so raw metrics are shown here instead. Why.
