**Vacaville, CA just fired a serious starting gun for non-lithium BESS**

The Vacaville Planning Commission has *unanimously* recommended a new BESS ordinance to City Council that effectively bans lithium-ion for larger battery projects and tightens siting + safety rules. This isn’t symbolic — it’s a real planning framework shift in California, the biggest storage market in the US.

Why this matters for Invinity:

* The ordinance explicitly excludes lithium-ion at scale, citing fire and safety risk.
* That *forces* developers to look at non-lithium chemistries.
* Vanadium flow batteries suddenly move from “interesting” to necessary in jurisdictions like this.
* Vacaville isn’t alone — local governments across CA are watching each other closely on BESS policy.

Right now, Invinity isn’t publicly tied to any Vacaville projects, but that’s almost the point. If lithium projects start getting blocked or rewritten, the addressable market opens up overnight for tech that already fits the rules.

This is a *game-on* moment — if Invinity can:

* Be visible to US developers *early*
* Move fast on permitting-ready reference designs
* Actually execute on delivery and scale

Regulation just tilted the board in Invinity’s favour.  
Now they need to seize it, not just talk about it.
