Ofgem has published a notice of its intention to impose a financial penalty on the National Grid Electricity System Operator (National Grid ESO) for its failure to comply with standard condition C16 of its transmission licence which requires accurate and unbiased forecasts of electricity demand to be provided. National Grid ESO has agreed to pay £1.5m in voluntary redress into Ofgem's voluntary redress fund. Ofgem confirmed that the money will be used to the benefit of energy consumers. Parties who object to the proposed penalty are advised to send their response to Ofgem by 5 pm on 29 April 2021.
