Well, Tirana's new 84MW/168MWh battery storage system – the largest in Southeast Europe – is flipping that script. Operational since February 2025, this $73 million project stabilizes a grid where renewable energy penetration jumped from 12% to 34% in just three years [4].
[pdf] The project, built by the Chinese state-run energy giant PowerChina and financed by Zambia’s national utility ZESCO, is designed to stabilize power for mining operations, the lifeblood of Zambia’s economy.
[pdf] It is scheduled to go live before 2030 and will mainly undertake peak shaving, valley filling, and energy storage tasks for the power grid in East China, the firm added. The power station will include six reversible hydro generators with a capacity of 400,000 kW per unit, GCL Energy noted.
[pdf] In April 2025, GSL Energy completed a 60 kWh wall-mounted home energy storage project in the UK, enabling customers to achieve energy independence and charge electric vehicles, with an estimated annual electricity cost savings of over £1,800.
[pdf] The world's first intelligent grid-forming photovoltaic and energy storage power station, tailored for ultra-high altitudes, low-temperatures and weak-grid scenarios, has been connected to the grid in Ngari prefecture, Southwest China's Xizang autonomous region.
[pdf] The project employs molten salt thermal energy storage technology that utilizes the temperature differential during the salt’s heating and cooling processes to store energy. Its primary goal is to resolve the conflict between thermal power unit load regulation and heat supply.
