Terabase Energy Secures $130 Million to Expand Solar Technology Deployment
Terabase Energy, a company specializing in solar technology, announced on Thursday that it has raised $130 million in funding, led by SoftBank, to scale its operations and expand the deployment of its solar technology for large projects. This funding round is the largest in the company’s history, bringing its total funding to $200 million. While the company did not disclose its valuation during this round, the investment highlights strong investor confidence in its future.
Despite solar and energy storage accounting for 84% of new electricity generation capacity added to the U.S. power grid in 2024, the sector is facing challenges due to new U.S. energy policies that continue to support fossil fuels. Additionally, venture funding in the U.S. has been relatively quiet in early 2025, with a few AI-focused companies capturing most of the spotlight.
Terabase Energy’s platform collaborates with solar power plant developers, engineers, and construction firms, streamlining processes through workflow digitalization and automation. The company plans to use part of its new funding to enhance its robotics-assisted assembly line, Terafab, designed to alleviate “bottlenecks in construction speed and workforce limitations.”
In addition, Terabase operates PlantPredict, a solar modeling software, and Construct, a construction management platform. Kentaro Matsui, managing partner at SoftBank Global Advisers, highlighted that the surge in energy demand, particularly from AI data centers, underscores the need for scalable and sustainable solutions.
SoftBank, which is known for financing early-stage technology companies, also supported Terabase through its Vision Fund 2. Other existing investors in the company include Breakthrough Energy Ventures, Fifth Wall, SJF Ventures, and EDP Ventures.
