Octopus Energy has urged customers to avoid running dishwashers, washing machines and similar plug‑in appliances between 6pm and 8pm on Wednesday as a solar eclipse blocks up to 95% of sunlight. The move aims to reduce peak demand and solar shortfall, with customers offered two hours of free electricity next weekend for taking part in the demand‑shifting. Regulators warn of potential grid stress and highlight flexible demand as a national resource.
The National Energy System Operator has issued precautionary margin notices amid the solar eclipse, signalling a temporary cushion between demand and supply.
