Context
Highest since we started · Price in Great Britain: 265.00 GBP/MWh in the 30-minute interval starting 2026-10-23 04:30 UTC. We have tracked this market since 2026-10-21. The window is short, so this says nothing about earlier years.
No earlier tracked value 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 checked after a second batch fetched at 2026-10-23 18:28 UTC (payload 53673e0b77): a later batch re-covered the same timestamp and still showed the value within 2%.
For comparison, the next most extreme valid reading in the same series is 254.80 GBP/MWh at 2026-10-23 16:00 UTC, out of 176 readings in the window.
These values are built from provisional operator data that can be revised, so each one is checked against later batches before it is marked Tracking and can be withdrawn if the source changes it.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.
