EDF Energy has agreed to make a voluntary redress payment of £6 million after Ofgem found the company “regularly sent misleading signals” to National Grid Electricity System Operator (ESO) over the true capabilities of its West Burton B power station in Nottinghamshire. Between September 2017 and March 2020 – a period of two and a half years – EDF Energy’s thermal generation subsidiary “frequently inflated” the minimum amount of power which it said the 1.3GW combined-cycle gas turbine plant was able to supply.
