Renewables supplied a majority of reported GB generation

Measurement. Renewable generation share reached 70.5 % against a 50 % reference.

Decision implication. A renewable-majority day tests how the system balances variable output, interconnection and dispatchable low-carbon generation across the full operating cycle.

Evidence boundary. The event is a deterministic threshold or record comparison. It identifies a measurement that warrants investigation; it does not assign causality or quantify commercial exposure.
