UK grid asks for backup power as Wednesday's eclipse cuts solar energy

NESO, the electricity grid operator, expects a 1,200-megawatt shortfall between 6pm and 8pm when the moon covers the sun. Wholesale energy costs are projected to rise past £210 per megawatt-hour, though officials insist no homes will face actual blackouts. Meanwhile, Octopus Energy is promising eligible households free weekend electricity if they manage to reduce their usage during the event.
