Why can these figures differ from the numbers in the news?
NESO and Elexon announce records from their own data, sometimes for transmission-connected plant only, and sometimes for a 5-minute reading. Electricity Live uses half-hour averages of all generation, including the NESO estimates for embedded wind and solar. The figures are close, but they can differ by a few tenths of a gigawatt. More →
How often do the records update?
Every 5 minutes. When new data beats a record, the record board, the record page and the day page change on the next update. More →
