Invinity Energy Systems ( (GB:IES) ) has issued an update.
Invinity Energy Systems has secured a sale of a 12 MWh Endurium vanadium flow battery system to the US Department of Energy’s Pacific Northwest National Laboratory for installation at PNNL’s Richland, Washington campus. The system will be used at the Grid Storage Launchpad to demonstrate the role of long-duration, utility-grade storage in providing 24-hour discharge, boosting operational resilience and cutting peak energy demand, reflecting a broader shift in the US power market—exemplified by PJM—towards prioritising eight- to ten-hour storage duration over short-term capacity. Supported by previously announced DOE funding and scheduled for delivery in the second half of 2026, the project deepens Invinity’s engagement with US grid innovation efforts and positions its vanadium flow technology as a contender for future long-duration storage deployments in North America.
The most recent analyst rating on (GB:IES) stock is a Hold with a £18.00 price target. To see the full list of analyst forecasts on Invinity Energy Systems stock, see the GB:IES Stock Forecast page.
