Historic Demand Data
This section contains historic electricity demand, interconnector, hydro storage pumping, Non-BM Short Term Operating Reserve (STOR), wind and solar outturn data.
This dataset is populated 21 days in arrears. It also undergoes retrospective corrections to Solar Capacity and Outturn, once new data becomes available. These corrections may occur several months after the first publication. Retrospective edits to Demand may occur, which make adjustments for Balancing Services undertaken by NESO.
