Swedish pumped hydro storage

Fortum has initiated a two-year feasibility study to explore potential for new pumped hydro storage facilities in Sweden. Pumped Hydro Storage’s solution enables large-scale electricity storage with the help of the proven technology of pumped storage. The storage method (PSH) is characterized by low cost, high efficiency, and a long service. The company has said it will examine commercial, technological, environmental and regulatory conditions for the new plants. Welcome to Sweden’s hydropower storage scene in 2025 – where ancient glaciers meet cutting-edge tech. Finnish energy firm Fortum Oyj (HEL:FORTUM), which operates three pumped hydro storage plants in Sweden, announced today that it will start an assessment process for the potential deployment of more such capacities across the country.
