With global oil prices fluctuating wildly (they've jumped 23% since January 2025) and tourism-dependent economies prioritizing sustainability, Port Louis' pumped hydro energy storage (PHES) project isn't just an alternative - it's becoming the backbone of the island's energy security strategy [1] [7].
[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] The largest pumped storage power station in terms of capacity in East China has entered the full-scale construction phase and is scheduled to begin generating power before 2030, said its operator, GCL Energy Technology Co Ltd.
[pdf] The following page lists all power stations that are larger than 1,000 in installed generating capacity, which are currently operational or under construction. Those power stations that are smaller than 1,000 MW, and those that are decommissioned or only at a planning/proposal stage may be found in regional lists, listed at the end of the page. World Bank Madagascar has Released a tender for Studies for various works to reinforce pumping stations, including pumping energy efficiency audit from the Antananarivo operations center, and for post-cyclo emergency actions in Architecture. The tender was released on Apr 09, 2024.
[pdf] Work has been completed on the world’s largest pumped storage station, at 3.6 GW, according to state news source China Energy News. The Fengning Pumped Storage Power Station in Hebei province, north of Beijing, started commercial operations Sunday on its twelfth and final reversible turbine unit.
[pdf] Pumped storage plants can operate with seawater, although there are additional challenges compared to using fresh water, such as saltwater corrosion and barnacle growth. Inaugurated in 1966, the 240 MW in France can partially work as a pumped-storage station. When high tides occur at off-peak hours, the turbines can be used to pump more seawater into the reservoir than the high tide would have naturally brought in. It is the only large-scale power plant of its kind.
