# TAR raises $120M Series A for off-grid AI data center power in Texas

> TAR has raised a $120 million Series A led by Spark Capital, at a $1 billion valuation, to tackle one of AI's most physical bottlenecks: power. Rather than wait years for utilities and grid connections, the company builds self-contained, off-grid systems that combine solar, batteries and natural gas to run AI data centers on their own dedicated supply. The bet is timely. Data center demand is outpacing what strained grids can deliver, and developers are increasingly desperate for power they can switch on quickly without a decade of permitting. TAR says it is already deploying a utility-scale facility of several hundred megawatts for a major customer in West Texas, and plans a manufacturing hub, TAR Terminal One, to scale up production. Reaching a billion-dollar valuation at Series A shows how much investor appetite has shifted toward the unglamorous infrastructure underneath AI. The models get the headlines, but the constraint is increasingly electrons, and whoever can deliver reliable off-grid power fastest may end up as important to the buildout as the chipmakers.
