"The UK is set to experience a joint record stretch of negative electricity prices on Saturday as Storm Amy drives huge amounts of wind power into the grid. Wholesale power prices will be negative for 17 hours from late Friday night, matching a record set in May, with the National Grid forecasting 20 gigawatts of wind power from the storm, more than three-quarters of the country’s total electricity demand. The current record day for wind power in the UK was in December last year, when generation hit 22.5GW."
