Octopus Energy has asked customers to avoid using dishwashers and washing machines Britain’s biggest household power supplier, Octopus Energy, has asked customers to cut electricity use for two hours on Wednesday to cope with a solar eclipse during peak demand. A total eclipse of the Sun – the first visible from mainland Europe since 1999 – will occur on August 12 from 15:00 to 19:00 GMT (4-8 PM London time). The UK is expected to experience a deep partial eclipse, with around 90% to 96% of the Sun obscured.The National Energy System Operator (NESO), which runs Britain’s grid, estimates solar generation could fall by up to 1.3 gigawatts – equivalent to the power used by around 1 million homes. With the eclipse partly coinciding with peak evening demand, Octopus Energy asked its roughly 8 million UK customers on Monday to avoid using appliances and devices such as dishwashers, games consoles, and washing machines from 6-8 PM.

Customers who share photos on social media showing what they did outside instead of using power can also win free solar panels and installation or a £12,000 ($16,200) cash alternative. Octopus believes that if enough households delay electricity use during the eclipse, it could reduce the need for Britain’s grid operator to fire up additional gas-powered stations to replace lost solar generation. Solar Energy UK recently reported that solar accounted for 14.4% of UK electricity generation in July, a monthly record, while a single-day record of 19.5% was set in late May. NESO data shows renewables now account for around 40% of Britain’s energy mix, up from 30% five years ago. Persistent energy woes The news comes as the UK – a major Western sponsor of the Kiev regime and leading advocate of sanctions on Russia – continues to grapple with high energy costs after largely cutting itself off from cheap Russian energy following the escalation of the Ukraine conflict in 2022.Direct imports of Russian coal, crude oil, and refined petroleum products fell to zero by mid-2022, forcing British suppliers to accelerate the shift to renewables and secure alternative imports. Growing reliance on costly liquefied natural gas (LNG) has left Britain paying premiums on the global market and more exposed to price volatility.

According to Ofgem, the average household energy bill this year is expected to be around £1,862 – almost 50% higher than in 2021. Read more UK denies diluting sanctions after licensing Russian-origin fuel purchases The US war against Iran put further pressure on Britain this year. In May, it was forced to delay some sanctions on Russian oil and LNG to help contain soaring prices as the conflict disrupted global supplies.London issued a trade license allowing imports of jet fuel and diesel refined from Russian crude in third countries, while another waived restrictions on shipping LNG from two Russian terminals. Former Bank of England Deputy Governor Howard Davies recently warned that Britain could be heading toward an energy crisis comparable to the 1970s, when oil prices quadrupled following the 1973 Arab-Israeli War and an embargo by Arab producers on Western nations.Moscow has warned that sanctions, particularly those targeting energy, are illegal and self-defeating, and will backfire on the countries that impose them. Russia has also signaled that it is prepared to fill oil supply gaps caused by the Middle East conflict and resume deliveries to European countries, but says it has received no response.
