Invinity Energy Systems (LSE:IES) has completed delivery of a 20.7 MWh vanadium flow battery at the Copwood VFB Energy Hub in East Sussex and says the project will connect to the GB grid and commence operation later this year.
The system is paired with a 3 MWp solar array, has capacity roughly equivalent to the daily electricity needs of about 3,000 homes and, once operational, will be Europe's largest vanadium flow battery and a UK-first at this scale, underscoring Invinity's role as a leading global manufacturer of utility-grade energy storage.
"Long-duration storage is the missing piece that turns intermittent wind and solar into reliable, on-demand power," Jonathan Marren said.
The Copwood project is intended as a flagship demonstration of long-duration energy storage technology to unlock more low-cost domestic renewables and reduce reliance on imported fossil fuels.
An announcement on Ofgem's LDES Cap and Floor scheme, which Invinity says could enable similar projects nationwide, is expected shortly.
Invinity expects the hub to start generating revenue before the end of the year, subject to final confirmation from the local distribution network operator, and will publish details of a site open day for shareholders and prospective customers in due course.
