Progress is rarely one big moment. It is a sequence of deliberate steps, taken in the right order, with the right partners.
Over the past several months, our new headquarters and manufacturing facility in Katy, Texas has moved from poured concrete to enclosed structures and defined interior space. This site will serve as TerraFlow Energy’s operational home and the foundation for scaled manufacturing of our LDUPS™ systems.
Below is a look at how the facility has come together, step by step.
Early Site Work: Pads Poured and Steel Staged
The project began with foundational site work. Concrete pads were poured, anchor bolts set, and structural steel staged across the footprint of Buildings A, B, and C.
At this stage, the scale of the site becomes visible. These slabs define not just where buildings will stand, but how production, testing, and movement through the facility will ultimately work.
This phase established the physical and operational geometry of the campus.
Late November 2025: Structure Begins to Rise
By late November, steel was going up and the first building began to take shape. Structural framing for the office and lab space was erected, marking a clear transition from site preparation to vertical construction.
This portion of the facility will house office functions, lab space, and our 1 MW-capable production pilot with full LDUPS capabilities.
With steel in the air, the project moved from plans on paper to something tangible.
December 2025: Foundations Set and Walls Go Up
In December, concrete pads for Buildings A, B, and C were complete, and the first exterior walls were installed. This phase locked in the site layout and marked a major step toward enclosure.
Somewhere in this window, a corner office was claimed early by Jon Parrella, though most of the focus remained on getting the fundamentals right.
January 2026: Enclosure and Interior Space
As of January, the roof is on and approximately 95 percent of the walls are up on the first building. Interior space is now clearly defined, revealing the open span of the manufacturing floor and how the facility will function day to day.
Recent aerial views of Buildings A and B show the broader campus coming together, with clear separation between structures and room for future growth.
This is the point where the facility begins to feel real, not just built, but usable.
Looking Ahead
This site is being built with intention. It is designed to support safe, durable manufacturing of long-duration energy storage systems and to scale alongside the needs of the grid.
As construction continues and the facility moves toward commissioning and early manufacturing operations, we will continue sharing progress along the way.
Progress you can see, and infrastructure built to last.
