READ MOREEnergy storage is the capture of energy produced at one time for use at a later time. Without adequate energy storage, maintaining an electric grid''s stability requires equating electricity supply and demand at every moment. System Operators that operate deregulated electricity markets call up natural gas or oil-fired generators to balance the
READ MOREEstonia''s first large-scale energy storage project, Zero Terrain, has received an official permit and construction can go ahead. Developed by Energiasalv, the 550 MW underground pumped-hydro storage plant has minor environmental and land-use impact and can therefore be implemented in urban areas. The project enables the deployment of
