Zero Terrain / Energiasalv

At Zero Terrain, we are proud to be at the forefront of the renewable energy revolution. We understand the urgent need for affordable, sustainable energy solutions with minimal environmental impact. Zero Terrain innovation ensures security against supply disruptions and crises while providing a cleaner and greener energy source for the future. Zero Terrain technology is based on the same principle as traditional pumped hydro storage solutions but with a crucial difference. By generating the necessary height variance and storage underground, we eliminate the need for altitude differences on the terrain. This approach not only reduces the above-ground footprint but also maximises underground volume. We can build Zero Terrain pumped-hydro storage on most flat land. Zero Terrain pilot project, Energiasalv, a large-scale energy storage initiative in Paldiski, northwest Estonia, employs our geotechnical pumped hydro storage solution, a cutting-edge 500MW underground battery designed to store surplus renewable energy efficiently. We are excited to announce that the Paldiski plant will be operational in Estonia in 2030 and provide flexible services to the Nord Pool Spot power market. We are confident that our innovative technology changes the renewable energy storage industry and provides a brighter and more sustainable future for future generations.
