Zero Terrain developed technology for pumped-storage hydroelectric power plants that allows them to be built on flat terrain without mountains that typically used for such projects. The technological innovation of Zero Terrain's solution lies in the placement of the lower reservoirs of the pumped-storage in the earth's crust with favorable geological conditions and the use of surface water bodies as upper reservoirs. Earth beams are used as the building structure, reducing the use of construction materials and the impact on land use. The modular design allows for increased storage capacity at a lower cost than any existing alternative. Low use of critical materials reduces supply risks. The company operates its own 500 MW hydroelectric storage facility, Energiasalv, in Estonia. During its nominal operating cycle of 30 hours, Energiasalv supplies 15 million kWh to the grid.
