Context

Lowest price in Great Britain: 0.00 GBP/MWh in the 30-minute interval starting 2026-10-22 03:30 UTC. This is a record since 2026-10-21, the first date in our data for this market. The window is short, so the record says nothing about earlier years.

No earlier confirmed record of this kind exists in our data window, so this entry is a baseline that later readings can beat. Baseline entries are not marked notable and are not offered to search engines.

No other metric published for this market sits close enough in time to this reading, so no operating conditions are shown. We do not estimate or fill in missing values.

First seen in a batch fetched at 2026-10-23 17:55 UTC (payload dd620af84d). It was confirmed after a second batch fetched at 2026-10-23 18:28 UTC (payload 53673e0b77): a later batch arrived, this feed does not republish old intervals, and the stored point stayed unrevised, unflagged and within 2%.

For comparison, the next most extreme valid reading in the same series is 12.63 GBP/MWh at 2026-10-23 22:00 UTC, out of 119 readings in the window.

Records are built from provisional operator data that can be revised, so each one is checked against later batches before it is confirmed and can be retracted if the source changes it. Readings outside market bounds, with a wrong unit, flagged by a quality gate or showing a price jump without a matching load change are rejected and never listed. See the methodology page for the full rules. Not for trading or operational decisions. Provisional data.
