Britain's electricity grid operator has warned suppliers about electricity use during this evening's solar eclipse.The National Energy System Operator (Neso) said it is taking the 'precautionary measure' to ensure a 'greater safety cushion' between demand and energy supply.The Government-owned organisation indicated it was forecasting a potentially tight period for electricity margins between 6pm and 8pm today.This is the fourth so-called electricity margin notice issued by Neso this year, with a previous notice issued last month during another heatwave.Bosses at Neso linked the latest industry notice to the solar eclipse, which is set to be the fullest for decades.Britain and Europe have become more reliant on solar power in recent years as part of a shift towards renewable energy sources.The electricity grid operator called on energy producers to help deliver a contingency of around 676 megawatts.The notice sends 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.
