Efficient energy storage is a fundamental pillar of the energy transition, which is why in the month of February we will be focusing on and sharing the most promising existing technologies in the field as well as news related to energy storage 🔋🔋

One of the most efficient large-scale storage systems in operation is hydroelectric pumping.  This is a cost-effective and proven technology that provides stability to the electrical system and can generate significant levels of clean energy with rapid response times.

Pumped hydroelectric storage facilities store energy in the form of water in an upper reservoir, pumped from another reservoir at a lower elevation. When the electricity is in high demand, power is generated by releasing the stored water through turbines in the same manner as a conventional hydropower station. When the demand is low (usually nights or weekends when electricity is also lower cost), the upper reservoir is recharged by using lower-cost electricity from the grid to pump the water back to the upper reservoir.
