TAR has raised $120 million in Series A funding at a $1 billion post-money valuation, with the round led by Spark Capital, to expand its off-grid power systems designed for AI data centers.
The Austin-based company plans to use the financing to grow its headquarters, expand its San Francisco engineering office, increase its logistics and manufacturing operations in West Texas and accelerate power deployments already underway.
TAR is addressing the growing electricity requirements associated with AI infrastructure by building self-contained modular systems combining renewable power generation and battery storage. The systems operate independently from the electric grid, allowing data center projects to add generation without competing with surrounding communities for grid capacity.
The company’s strategy is built around controlling the entire project lifecycle rather than relying on multiple outside contractors. TAR manages site selection, detailed engineering and design, procurement, logistics, civil construction, commissioning and ongoing operations.
It has also developed a purpose-built deployment automation stack intended to install generation capacity more quickly, at larger scale and with less field labor than conventional construction approaches. Its team includes energy industry veterans from Hut 8, AES and Vistra, along with robotics engineers with experience at Zipline, GrayMatter Robotics and Lucid Motors.
TAR is currently executing a utility-scale deployment with one of the largest neoclouds, developing a dedicated project campus and completing TAR Terminal One, its manufacturing and logistics center in West Texas.
The company was founded in 2026 by Pat Becker and Leonhard Soenke and is focused on building off-grid power systems for AI data centers at gigawatt scale. TAR is also hiring across engineering, robotics, power systems, operations, supply chain and project management as it scales.
KEY QUOTES:
“To lead the frontier of AI after a lack of investment in the electrical grid for decades requires a complete rethinking of energy deployments. Gigawatt-scale deployments in tight time windows necessitate owning the full stack end-to-end,” said Pat Becker, co-founder of TAR.

“We are excited by the demand from our customers. Our focus now is scaling supply to make a real impact on the power shortage stopping the scaling of compute,” said Lenny Soenke, co-founder of TAR.

“Power is becoming the main bottleneck to scaling compute. We will need innovation, unprecedented speed and exceptional companies unblocking it at every level,” said Will Reed, General Partner at Spark Capital.
