Enter pumped hydropower storage (PSH), the "Swiss Army knife" of energy grids. While solar panels nap at night and wind turbines catch their breath, PSH acts like a giant battery, storing excess energy by pumping water uphill and releasing it when demand spikes.
[pdf] The World Bank recently approved a $20 million loan facility for Central Asian energy storage projects, with Khujand being a primary beneficiary. Tajik authorities envision scaling up to 500 MWh by 2030, potentially connecting with neighboring Uzbekistan's power grid.
[pdf] Construction work will include the development of 10 MW of solar power along with an energy storage system with two-hour lithium-ion batteries with a capacity of approximately 13 MW / 26 MWh, as well as connection to LUCELEC’s 66 kV transmission grid.
