Construction work is set to start in summer 2024 on the first pumped storage project in Estonia, with developer Energiasalv announcing it has received an official permit to build the 550MW plant. 

Named Zero Terrain, the underground project is set to be constructed in Paldiski, northwestern Estonia. Energiasalv said the storage plant has minor environmental and land-use impact and can therefore be implemented in urban areas. The project enables the deployment of renewable energy generation in the region and will significantly lower consumers’ electricity bills.

“Emission-free energy with a high security of supply at an affordable price is only possible with large-scale and long-term energy storage. I am proud that Energiasalv’s Zero Terrain project can provide the region with an energy supply that will meet future requirements,” said Peep Siitam, CEO of Energiasalv. “Considering we are in the middle of an energy crisis, our team is moving at a speed and strength comparable to the water itself.”

“Having completed our permitting process with the Estonian Consumer Protection and Technical Regulatory Authority, we are glad to announce that we will continue with the pre-qualification for the construction procurement in the beginning of February. We aim to finalize the tender process by the end of 2023 and start construction on the project in the summer of 2024,” added Sander Astor, Chief Technical Officer of Energiasalv. .

Energiasalv’s Zero Terrain is an EU Project of Common Interest (PCI project). Being the strategic infrastructure project, its preparation has been supported by the Connecting Europe Facility – managed by the European Climate, Infrastructure and Environment Executive Agency (CINEA). Energiasalv is owned by the Estonian energy company AS Alexela, Baltic-Polish renewable energy company Sunly AS, and Vool OÜ belonging to the company’s CEO.
