Context
Longest negative price streak in Great Britain: an unbroken run of 5 consecutive 30-minute intervals with a price below zero, starting at 2026-10-25 02:00 UTC and lasting 2:30 h (h:mm). This is the longest such run since we started tracking this market on 2026-10-21.
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 2026-10-25 07:38 UTC (payload bc800fd8a4). It was checked after a second batch fetched at 2026-10-25 07:55 UTC (payload 64b10b991a): a later batch re-covered the same timestamp and still showed the value within 2%.
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operator data that can be revised, so each one is checked against later batches before it is marked Tracking and can be withdrawn if the source changes it.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.
