UK grid operator warns of solar eclipse threat to electricity supply

Britain's grid operator, NESO, warned of a Wednesday evening supply shortfall as a near-total solar eclipse — the most dramatic since 1999 — could cut up to 1,100 megawatts of solar generation. A summer heatwave compounds the timing. Gas-fired stations were ordered to ramp up. NESO called it precautionary and said supply to customers is not at risk.
