US-based Terabase Energy has secured $130 million in series C funding led by SoftBank Vision Fund 2 to accelerate the deployment of its digital and automation technologies for utility-scale solar projects, the company said on Wednesday.

The funding, which brings Terabase’s total financing to over $200 million, will help scale its robotics-assisted solar construction system, Terafab, and enhance its digital ecosystem, which includes AI-driven design and construction management tools.

“SoftBank Vision Fund’s investment reflects our shared commitment to leveraging advanced technology to drive the future of renewable energy,” said Matt Campbell, CEO of Terabase, in a statement. “This funding validates our mission and provides the resources to scale our platform, paving the way for the terawatt era of solar.”

Expanding Terafab’s Deployment

Terafab, which automates the assembly of solar plants, has already installed 40 megawatts across multiple US projects.

The company plans to expand its deployment to hundreds of megawatts through 2026, doubling installation productivity and improving worker safety by eliminating manual lifting of heavy components.

“The surge in energy demand, particularly from AI data centers, underscores the urgency of scalable, sustainable solutions,” said Kentaro Matsui, managing partner at SoftBank Global Advisers. “Terabase’s innovative approach to digitalizing and automating solar power plant deployment positions it as a leader in this transition.”

Battery Storage Economics

The investment follows advances in battery storage economics that enable solar plants to deliver cost-competitive electricity around the clock.

With growing energy demand from onshoring of manufacturing and data center expansions, utility-scale solar remains the fastest-growing and most cost-competitive source of new generation capacity.

Since its inception, Terabase has supported over 12 gigawatts of solar projects through its suite of solutions, including PlantPredict solar modeling software and the Construct construction management platform. The latest funding round will allow the company to scale its technology and reshape how large-scale solar farms are built.
