TAR Raises $270 Million Seed Round for Modular Power Systems Targeting Data Centers

Green energy infrastructure startup TAR said it has raised a $270 million seed round to develop modular, plug-and-play power systems for data centers, aiming to ease power supply and deployment bottlenecks tied to AI-driven demand. According to ChainCatcher, the company’s approach is designed to reduce reliance on public grids and avoid delays linked to grid interconnection queues, permitting timelines, and power price volatility. TAR said its system combines solar, wind, battery storage, and natural-gas backup generation to provide near 24/7 on-site power. The company’s co-founders said the core strategy is factory prefabrication, pre-assembly, and pre-testing to shorten deployment timelines and enable faster data center commissioning. In a pilot project, TAR said the system can deliver about 10 MW of stable power, and it plans to deploy more than 200 MW of steady-load capacity by 2027. TAR said its first customer is an unnamed “neocloud” provider seeking a faster path to powering AI compute infrastructure. TAR said it is not primarily targeting costs below traditional grid power, but prioritizing speed, claiming its off-grid system can be deployed in about three months while avoiding time costs associated with grid access and land constraints. The company cited research indicating power availability is a key constraint on data center expansion as AI compute demand grows.
