Kruonis Pumped Storage Plant, Pumped-storage power station in Kruonis Eldership, Lithuania

Kruonis Pumped Storage Plant is a pumped-storage hydroelectric power station near Kruonis, Lithuania. It uses two reservoirs at different elevations to store and generate electricity, with a total capacity of 900 MW.

Planning for the plant began in the 1960s to balance the energy system, and construction started in the 1980s. The first generator was launched in 1992, with others following through the 1990s.

The plant is a source of local pride, often mentioned in conversations about energy in the region. Its presence has shaped the nearby town of Elektrėnai, where many workers and their families settled.

The plant is not open for regular visits, but you can see the upper reservoir and the surrounding infrastructure from public roads. The area is best explored by car, as the site is spread out and public transport is limited.

The upper reservoir sits about 100 meters above the lower one, and the plant can switch from pumping to generating in under two minutes. It is the only facility of its kind in the Baltic states.
