("Invinity" or the "Company")

Invinity selected for 7.8MWh of California energy storage projects

Four projects awarded funds by the California Energy Commission to rely on Invinity batteries

Invinity Energy Systems plc (AIM:IES), manufacturer of vanadium flow batteries ("VFBs") for the large-scale energy storage requirements of businesses, industry and electricity networks, is pleased to announce its participation in four separate energy storage projects funded by the California Energy Commission ("CEC").

In January 2020, the California Energy Commission, California's primary energy policy and planning agency, released a grant funding opportunity to promote "…innovative longer-duration non-lithium ion energy storage…" Invinity collaborated with four partners to submit independent proposals. Of the 23 submissions received by the CEC, eight awards were proposed, including all four Invinity submissions.

The Company is working to conclude final contracts with its project partners towards a 2021 delivery of the combined 7.8 MWh of Invinity's VFBs. Upon the deals reaching contractual close, Invinity will provide an update, including additional details of the projects.

Larry Zulch, Chief Executive Officer at Invinity said:

"The California Energy Commission has taken a leadership role in driving the diversity of energy storage required in the future. We were fortunate to collaborate with some tremendous partners on this opportunity and thrilled to have all four proposals with which we were involved chosen for funding. Our success in this solicitation is an enormous vote of confidence in Invinity's vanadium flow batteries and their ability to help ensure a robust, clean, and inexpensive energy supply in the future."
