Ignitis Group says it will increase the capacity of the 900 MW Kruonis Pumped Storage Plant by another 110 MW. It notes that the expansion project will be finalized by the end of 2026.
The New Zealand government will investigate the viability of establishing a pumped hydroelectric facility on the South Island. The project could provide up to 8.5 TWh of annual generation and storage capacity to support the nation’s transition to 100% renewable electricity generation.
When it comes to gravity batteries, pumped-hydro storage is the gold standard, but its cost and topography-specific limitations are driving innovations ranging from freight-train braking to super-dense liquids. We consider whether any of the new technologies can punch above their weight.
Long-duration energy storage (LDES) is essential for decarbonizing the grid but gigawatt-hour scale systems continue to be tricky for companies with big ideas. Here are some of the latest innovations across a flourishing array of new – and old – ideas.
General Electric has switched on two more 300 MW pumped storage turbines at a 1.2 GW hydro battery complex in China’s Anhui province, after finalizing the facility’s first 600 MW unit in December. The project has completed a trial period and commercial operations are now fully underway.
Developer rPlus Hydro has submitted an application for a final license to the US Federal Energy Regulatory Commission for the Seminoe project– a milestone reached by only a few pumped storage projects over the last 20 years.
Energiasalv has secured a construction permit to build a 6 GWh pumped hydro storage plant in Paldiski. Work on the facility is planned to start in the summer of 2024.
General Electric said one of its subsidiaries has deployed two 300 MW pumped storage turbines at a 1.2 GW hydro battery complex in China’s Anhui province.
Greenko has won NTPC Renewable Energy’s tender for 3 GWh of energy storage capacity. Its pumped storage bid was the lowest in the tech-agnostic tender.
Suomen Energiavarasto Oy has secured €26.3 million ($27.5 million) from the Finnish government to build an underground pumped hydro project at a former zinc and copper mine.
