Invinity Exceeds 10 GWh Dispatched for Customers
Significant performance milestone demonstrates the durability and flexibility of the Company's technology in demanding, real-world applications.
Invinity Energy Systems plc (AIM: IES), a global leader in vanadium flow battery technology, is pleased to announce that its global operating fleet of vanadium flow batteries has now dispatched more than 10 GWh of energy in service to customers.

This landmark achievement, surpassed in recent days across the Company's installed base of VS3 and Endurium battery systems, demonstrates the ability of Invinity VFBs to deliver sustained, high-cycling performance in demanding commercial applications and represents another significant validation of Invinity's technology. Of particular note is the strong performance delivered by Invinity VFBs installed at the Viejas Resort and Casino in California by Indian Energy. This battery system has recently delivered more than 0.5 GWh of energy since entering full operation and has consistently met and exceeded warranted performance parameters across multiple metrics during this time.
The cumulative volume of energy dispatched by the Company's operating fleet has increased 85% year-on-year, reflecting growing adoption of Invinity technology across a diverse range of grid-scale and commercial energy storage applications. Invinity batteries are deployed at customer sites across the UK, Europe, USA, Canada, Australia and Southeast Asia, with additional projects on track to enter operation in the coming months including the Copwood VFB Energy Hub in the UK, expected to become the largest operating vanadium flow battery in Europe.

Surpassing 10 GWh of dispatched energy represents a significant proof point for the maturity, reliability and bankability of Invinity's technology. Few emerging energy storage technologies have accumulated comparable commercial operating experience, making this growing operational track record a key competitive differentiator. The demonstrated durability of Invinity's vanadium flow batteries, combined with long-term customer support, has helped build a strong base of satisfied customers, generated repeat business and created a solid platform for further expansion within existing accounts.
Jonathan Marren, Chief Executive Officer at Invinity said:
"Surpassing 10 GWh of discharged energy is a major achievement for Invinity and a powerful proof point for the maturity of our technology. Delivered through real-world operation across our global fleet, this milestone reflects both the strong performance of our vanadium flow batteries and the hard work of the team behind them. As global demand for energy storage continues to increase, this unparallelled operational experience gives current and prospective customers confidence that Invinity's systems can perform reliably when it matters most."
