Octopus Energy has launched an 'Eclipse Power Down' session asking eligible customers to use less electricity between 6 p.m. and 8 p.m. on Wednesday 12 August, as the Moon obscures up to 95 per cent of the Sun in parts of Britain.
The company has encouraged households to move activities such as using washing machines and dishwashers outside that period. The timing matters because the resulting reduction in sunlight is expected to affect solar generation while electricity demand can begin increasing as people return home and start preparing meals.
