Eesti Energia is carrying out preliminary design and environmental impact assessment for what would be the first pumped storage hydroelectric plant in Estonia.

The planned 225MW plant is planned for the industrial area of the Estonia mine in Ida-Virumaa. It’s upper reservoir will be built on a tailings structure, and a closed mine will be used as the lower reservoir. The project is expected to start operating in 2026,

"Ensuring Estonia's energy security and energy independence with our own assets is more important than ever before," said Margus Vals, a member of the board of Eesti Energia. "In light of the connection to the continental European electricity system, which is planned for 2026 at the latest, it is extremely important that the necessary energy markets and production or storage assets are created in the Baltic States, with which security of supply can be ensured in the greenest and most affordable way possible."
