Acquired by Drax Group in December 2018, the site is one of only four pumped storage hydro stations in the UK and has the capacity of 440 MW - enough to power more than 500,000 homes. Pumped storage hydro is the only tried and tested technology for
Pumped storage is currently the only way to store electricity on a large scale. In Belgium, the Coo station is therefore essential for the balance on the grid. The turbines can be started up at any time to offset a sudden drop in generation or to absorb excess electricity. As such, when demand is too low Coo stores the power generated elsewhere

Spain currently has 18 pumped-storage hydroelectric power plants with an installed capacity of 6 GW. What is a pumping station? Pumped-storage power plants have two water reservoirs at different heights. During off-peak hours, water is pumped from the lower reservoir to the upper reservoir. Once there, this water is used to generate electricity
