Invinity Energy Systems, a British manufacturer of vanadium flow batteries, has partnered with UK-based energy infrastructure developer Frontier Power to deploy up to 2 GWh of Invinity’s ENDURIUM vanadium flow batteries. This collaboration aims to enhance the UK’s energy security and reduce costs by targeting bids for Ofgem’s Long Duration Energy Storage (LDES) Cap and Floor scheme, expected to open between Q2 and Q3 2025.

Under the agreement, Frontier Power has secured the right of first refusal on 2 GWh of Invinity’s manufacturing capacity. Frontier will lead project development, including financing, land acquisition, and planning permissions, while Invinity will supply the flow batteries. The partnership also explores opportunities beyond the UK, targeting markets in Japan, Korea, Vietnam, Malaysia, the USA, and the EU.
Invinity, headquartered in the UK, has recently expanded its manufacturing capabilities with a new facility in Motherwell, Scotland, increasing its UK assembly capacity to over 500 MWh per year. This expansion underscores Invinity’s commitment to bolstering domestic battery manufacturing and supporting the UK’s transition to a low-carbon energy system.
The UK’s cap and floor regime is designed to encourage investment in long-duration energy storage, aiming to reduce the estimated £3 billion spent annually on wind energy curtailment. By integrating large-scale LDES solutions like Invinity’s ENDURIUM batteries, the UK can enhance grid stability, optimize renewable energy utilization, and lower energy costs for consumers.
This partnership marks a significant milestone in advancing sustainable energy infrastructure, positioning the UK as a leader in non-lithium energy storage solutions.
