Read our Privacy noticeBritain’s electricity grid operator has cancelled its call to the industry to generate more power during Wednesday evening’s solar eclipse. Britain and Europe have become more reliant on solar power in recent years as part of a shift towards renewable energy sources. The last eclipse of its kind in August 1999 only lasted for 20 minutes, but saw a record swing in power demand as Britons rushed outside to watch the event. The electricity grid operator had called on energy producers to help deliver a contingency of around 676 megawatts. The notice sent a message to the electricity market that the operator would like a greater cushion, or margin, between power demand and supply for a limited period.
