Invinity Energy Systems plc (AIM:IES) has announced two new sales agreements alongside a detailed update on trading performance through the end of 2025. The Company also provided an overview of operational progress, product developments, and its contracted order position entering 2026.

2025 Trading Overview

Invinity entered 2025 following the launch of its Endurium product and shipment of its first 1.2 MWh demonstration system from its Vancouver manufacturing facility. During the year, the Company focused on reducing Endurium product costs while expanding its addressable markets and improving internal margins.

By year-end, Invinity reported progress across commercial activity, operations, product range expansion, and cost reduction initiatives. Commercially, the Company announced multiple sales during the year, including Endurium systems supplied to Pacific Northwest National Labs, STS Group, Charles Murgat, and Ideona Group, alongside confirmation that the Invinity Copwood VFB Energy Hub would proceed.

In addition, Invinity continues to engage with counterparties connected to 16.7 GWh of bids submitted under the UK Long Duration Energy Storage Cap & Floor Scheme.

Operational and Manufacturing Update

Operational deliveries expected for completion in 2025 were concluded, including shipments to HITT, STS, Ideona, and the Copwood Energy Hub, which is expected to be fully operational in the first half of 2026. Enel X has been engaged to manage dispatch and revenue optimisation for the Copwood project.

Manufacturing capacity was expanded during the year through the introduction of a semi-automated stack line in Scotland and the transfer of Endurium balance-of-system manufacturing to partner Baojia in China. Invinity can now ship Endurium systems from the UK, Canada, and China, with additional capacity planned for the U.S. and India through its partnership with Atri.

Revenue and Order Book

The Company anticipates recording approximately £17m in revenue and project grant income for 2025, following shipments to STS, Ideona, and HITT, and the receipt of grant funding related to the Copwood project. Licence fee income from UESNT was not included, with discussions expected to continue into 2026.

As of today, Invinity reports a 2026 order book of £17m, comprising around £8m of signed committed contracts and £9m of signed but uncommitted agreements, where timing remains subject to customer approvals and project milestones.

Follow-On Sales in Hungary

Invinity has also signed two new agreements with Central European Vanadium Storage Kft, a subsidiary of Ideona, to supply 20 MWh of Endurium vanadium flow battery systems for two solar-plus-storage projects in Hungary. The projects include an 8 MWh installation in Veszkény and a 12 MWh system in Dunaföldvár, both co-located with existing solar photovoltaic assets and supported in part by Hungarian government funding.
