The day Europe’s power grid came close to a massive blackout
Large amounts of intermittent electricity create huge swings in supply which the grid has to be able to cope with. The issue isn’t confined to Europe. Australia has had teething problems in the transition to a cleaner network. Wind power was blamed for a blackout in 2016 that cut supply to 850,000 homes. The nation is looking to storage as a solution and was the first country to install a 100 megawatt megabattery in 2017.
