Solar technology firm Terabase Energy has raised $130 million in a funding round led by SoftBank, aiming to expand its technology deployment for large-scale solar projects. The latest investment brings the company’s total funding to $200 million, though it has not disclosed its current valuation.
The funding comes as the solar industry faces headwinds despite accounting for 84% of new electricity generation capacity added to the United States grid last year. Recent shifts in U.S. energy policy, which have placed renewed emphasis on fossil fuels, present further challenges for the sector.
Terabase Energy provides digitalisation and automation solutions for solar power plant developers, engineers, and construction firms. The new capital will support the development of its robotics-assisted assembly line, Terafab, designed to address “bottlenecks in construction speed and workforce limitations.” The company also operates PlantPredict, a solar modelling software, and Construct, a construction management platform.
“The surge in energy demand, particularly from AI data centres, underscores the urgency of scalable, sustainable solutions,” said Kentaro Matsui, managing partner at SoftBank Global Advisers.
SoftBank, which has a history of backing early-stage technology firms, previously invested in Terabase through its Vision Fund 2. Other investors include Breakthrough Energy Ventures, Fifth Wall, SJF Ventures, and EDP Ventures.
The funding round comes amid a broader slowdown in U.S. venture capital investment in early 2025, with AI-integrated firms being among the few to attract significant attention.
