"To achieve a safe and secure net zero power grid, we need to have a new generation of pumped storage hydro plants to balance our grid," commented Ian Kinnaird, Drax's Scottish Assets Director. "As the UK increasingly relies on intermittent renewables to keep our lights on, there is a growing need for flexible power sources to plug the gap when the wind doesn't blow, or the sun doesn't shine. With its reversible turbines, Cruachan can also store excess power from Scotland's wind turbines when they are generating more renewable electricity than we need, helping to stop valuable green power from going to waste.
