TAR Raises $120M Series A Led by Spark Capital for Off-Grid AI Data Center Power
TAR Secures $120M Series A to Scale Off-Grid Power for AI Data Centers
TAR, an Austin, Texas-based energy infrastructure company, has raised a $120 million Series A round. The round was led by Spark Capital, with participation from Buckley Ventures and Align Fund. The funding was announced on September 10, 2026.
What TAR Does
TAR builds off-grid, modular power systems that combine renewable energy generation and battery storage for AI data centers. The company targets AI and neocloud operators that are constrained by grid access — a growing segment of the market where power availability, not compute hardware, is often the binding constraint on deployment.
Rather than acting as a traditional EPC contractor or equipment vendor, TAR verticalizes the full deployment chain. According to the company, that scope includes:
- Site selection
- Engineering
- Procurement
- Logistics
- Civil works
- Construction
- Commissioning
- Ongoing operation
TAR executes this scope using a purpose-built deployment automation stack, which the company says allows it to install generation capacity faster and with less field labor than conventional construction methods.
Company Background
TAR was co-founded by Pat Becker and Leonhard Soenke. The company operates an Austin headquarters, a San Francisco engineering office, and the TAR Terminal One manufacturing and logistics center in West Texas.
The combination of a Texas headquarters, a West Texas manufacturing and logistics hub, and a Bay Area engineering presence reflects the company's positioning at the intersection of energy infrastructure and the AI data center buildout. West Texas has become a focal point for large-scale generation and storage projects, while San Francisco provides access to the engineering talent pool serving AI infrastructure customers.
Why the Round Matters
The Series A is a significant step for a company operating in the physical infrastructure layer of the AI economy. Off-grid and modular power approaches are increasingly relevant as data center developers face interconnection queues, transmission constraints, and long lead times for grid-supplied electricity.
TAR's vertical integration — spanning site selection through ongoing operation — is intended to compress deployment timelines. The company's stated differentiator is its deployment automation stack, which it applies to reduce field labor requirements relative to conventional construction.

Acquisition Context
The Series A positions TAR as a scaled player in the off-grid power segment serving AI and neocloud operators. For strategic acquirers — including energy majors, infrastructure funds, data center operators, and industrial construction firms — TAR's combination of vertical integration, a manufacturing and logistics center, and a deployment automation stack represents a differentiated asset in a market where power delivery is the primary bottleneck.
The company's customer base of AI and neocloud operators, who are constrained by grid access, aligns with demand trends driving investment into behind-the-meter and off-grid generation. TAR's full-chain scope means an acquirer would gain not just a technology stack but deployment, manufacturing, and operations capabilities.
Summary
TAR has raised a $120 million Series A led by Spark Capital, with Buckley Ventures and Align Fund participating. The Austin-based company builds off-grid, modular power systems combining renewable generation and battery storage for AI data centers, and verticalizes the deployment chain from site selection through ongoing operation using a purpose-built automation stack. The round was announced on September 10, 2026.
