Octopus Energy is asking eligible customers to cut electricity use during Wednesday's partial solar eclipse, with its Eclipse Power Down session running from 18:00 to 20:00 on 12 August. Solar generation will fall as evening demand rises during the event, and customers who use less power than usual can earn one free hour of electricity on Sunday 16 August.
The Moon will cover about 90 to 96 per cent of the Sun across the UK and Ireland, depending on location. Royal Observatory Greenwich says the event will bring the greatest solar coverage seen from the UK and Ireland since 1999.
