What are the pumped storage projects in helsinki

Kemijoki Oy plans to build several 200–600 MW pumped storage plants to be built in the Kemijoki water area. Depending on the scale of the investment, this could increase the regulating capacity of hydropower in Finland by up to 4,000 MW. But when Finland’s capital throws its hat into the renewable energy ring with the Helsinki pumped storage project tender, suddenly everyone from engineers to environmentalists sits up straighter. Summary: Helsinki is rapidly becoming a hub for cutting-edge energy storage solutions. The pumped hydro energy storage (PHES) is a well-established and commercially-acceptable technology for utility-scale electricity storage and has been used since as early as the 1890s.
