Pumped storage capacity is constantly growing

As shown in International Hydropower Association’s (IHA) “2015 Key Trends in Hydropower” report, 1.46GW of new pumped storage was put into operation in 2014 alone, increasing by around 10% the world’s total pumped storage capacity.

In Europe only, the technology continues to be a focus of activity with new facilities totaling 8,600 MW in the planning and construction stages, reflecting a greater need for balancing and ancillary services to support large influxes of variable wind and solar power using reliable, local and clean resources.
