TAR has raised a $120 million Series A for an approach to AI infrastructure that starts with its own electricity supply. The Austin company builds off-grid power systems for data centers, combining renewable generation with batteries. Its intended customer is a computing operator that needs substantial power without waiting for a conventional grid connection.
The system pairs equipment that generates electricity with storage that can make that output available at a different time. TAR describes modular installations in West Texas, built separately from the local grid. That is a different proposition from selling a data-center customer an electricity contract: the company has to deliver the physical infrastructure supporting the supply.
FinSMEs describes TAR's role across the deployment process, from choosing a site and engineering the installation to procuring equipment, organizing logistics, managing construction and commissioning the system. TAR also handles ongoing operations. Bringing those activities into one company is intended to reduce the coordination work between separate contractors. It makes execution and supply-chain management part of the product, not an afterthought once a design is finished.
TAR says it is carrying out a utility-scale deployment with an unnamed large AI cloud provider while developing a dedicated project campus. Its West Texas manufacturing and logistics center, called Terminal One, is still being completed. These are work-in-progress milestones, not a claim that a gigawatt of power is already operating. The company has not named the customer in the announcement.
Spark Capital led the round at a $1 billion post-money valuation, with Buckley Ventures and Align Fund among TAR's backers. Pat Becker and Leonhard Soenke founded the company in 2026. It plans to grow its Austin headquarters, San Francisco engineering operation and West Texas deployment base. Its public careers page likewise positions the business around building energy infrastructure, rather than developing a standalone software service.
The practical question is whether TAR can turn that integrated construction model into dependable power on a customer's schedule. Avoiding a grid queue does not eliminate the work of finding equipment, completing a site and operating it reliably. The company now has capital to expand that effort; delivered capacity and continuity of supply will be the useful measures of progress.
