This group of pages contains functions to view 2-14 day forecast values including demand, surplus, transmission demand and generation forecasts. Transmission demand INCLUDES Interconnector flows and demand from station transformers and pumped storage units while normal demand INCLUDES transmission losses but EXCLUDES station transformer load, pumped storage demand and interconnector demand. All figures are MW values

Important Note: Please note that from 16th October 2015 Surplus levels on the BMRS which previously noted wind at 100% output capacity now included wind at forecast output levels in the 2-14 day-ahead surplus. Interconnector flows have been set to zero in the Surplus calculation. These changes have been made by National Grid.
