"G.B. National Grid Status. It also has links to historical data as well."
Interestingly, even at 1240am, a time I would expect to be pretty much the bottom of the trough/graph in terms of demand, we are still taking about 10% of the national demand from external interconnects from France, Netherlands etc., although, also interestingly, wind is shown as the largest single contributor at just over 32% and coal at 0%
