TerraFlow Energy has put down serious roots in Katy, unveiling a 100,000-square-foot headquarters and pilot manufacturing campus that it hopes will power the next wave of long-duration energy storage. The new site is built to house both corporate offices and early-stage production, giving the startup a home base for assembling and showcasing its long-duration flow-battery systems for data centers and other large power users.
Company hosts pre-opening reception
At a pre-opening reception covered by the Houston Business Journal, CEO Jon Parrella walked partners and local officials through the vision for the Katy campus, describing it as both a production floor and a live demo space for TerraFlow's LDUPS and vanadium flow battery systems. According to the outlet, attendees included local economic development leaders and industry partners who got an early look at how the company plans to scale up.
Permits show where and how it was built
State construction filings offer a peek behind the curtain on the buildout. A record with the Texas Department of Licensing and Regulation lists the project as "Terraflow Greenbush" at 3127 Greenbusch in Katy and describes a 100,000-square-foot interior buildout of existing PEMB buildings. The filing pegs the estimated project cost at about $4.9 million and notes that the work is a privately funded interior buildout.
What will happen inside the building
In its own announcement, TerraFlow Energy said roughly 60,000 square feet of the campus will be dedicated to TerraFlow's offices and assembly operations. The remaining 40,000 square feet is slated for Storion Energy, which will use the space for stack and electrolyte production. TerraFlow described the Katy facility as a small-scale manufacturing and demonstration site that is meant to speed up pilot deployments and early commercial rollouts rather than serve as its full-scale factory.
Partners, pipeline and the pitch to data centers
The shared campus is an extension of an existing relationship. TerraFlow's co-location with Storion is tied to a supply and stack agreement that backed TerraFlow's 9.6 MW, 5-hour vanadium flow battery project in Bellville, according to Storion Energy. The strategy also lines up with a broader case for flow batteries reported by the Houston Chronicle, which highlighted TerraFlow's argument that these systems can act as a "shock absorber" for the surging and unpredictable power needs of AI-heavy data centers, as part of a larger set of factory ambitions elsewhere in Texas.
Local impact and next steps
TerraFlow has not released detailed hiring projections for the Katy location, and public construction filings indicate the site is initially focused on assembly, testing and demonstration while the company pursues larger-scale manufacturing plans. The firm notes local ties on its website, including CEO Jon Parrella's role on the Katy Economic Development Council's board of governors, a connection the company says will help sync up workforce and training programs with its growth plans in the area.
