• Terabase Energy secured $130 million in funding led by SoftBank, bringing its total funding to $200 million.
  • The company will use the funds to develop its robotics-assisted assembly line, Terafab, which aims to improve solar plant construction efficiency.

Solar technology company Terabase Energy has raised $130 million in a funding round led by SoftBank to accelerate its technology deployment for large-scale solar projects.

The latest investment, the largest in the company’s history, brings its total funding to $200 million. The company has not disclosed the valuation at which the funds were raised.

Despite solar and energy storage accounting for 84% of the new electricity generation capacity added to the U.S. power grid in 2024, the sector faces challenges due to the government's evolving energy policies, which have shown renewed support for fossil fuels.

Additionally, venture capital funding in the U.S. has slowed in early 2025, with only select artificial intelligence (AI)-integrated companies drawing significant investor attention.

Terabase Energy provides digital tools and automation solutions to solar power plant developers, engineers, and construction firms. The company’s robotics-assisted assembly line, Terafab, aims to reduce construction bottlenecks and workforce constraints. The newly secured funds will be used to further develop this technology.

Beyond Terafab, Terabase operates PlantPredict, a solar modeling software, and Construct, a construction management platform. These tools support the company’s goal of improving efficiency in the solar industry.

SoftBank, which has a history of backing early-stage technology firms, previously invested in Terabase through its Vision Fund 2. The latest funding round also saw participation from existing investors, including Breakthrough Energy Ventures, Fifth Wall, SJF Ventures, and EDP Ventures.

“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.

With its expanded capital, Terabase Energy aims to enhance its technological capabilities and continue its efforts to streamline solar project development in the face of shifting market dynamics.
