What They Do
Terra-Gen focuses on renewable energy production, specializing in utility-scale projects across the United States. The company has a diverse portfolio that includes wind, solar, and battery energy storage technologies, providing comprehensive services from development and financing to construction and ongoing operations and maintenance of large-scale energy assets (source: terra-gen.com). Their offerings include operational wind farms and solar photovoltaic facilities, which are often paired with lithium-ion battery storage, totaling 5.1 GWh across various sites. This integrated approach allows them to supply dispatchable renewable power, enhancing grid resiliency for utility customers (source: cbinsights.com). Terra-Gen's target market primarily consists of utilities connected to major grids, such as California's CAISO and Texas, where they deliver renewable energy solutions that meet the growing demand for sustainable power (source: igneoip.com).
Projects & Track Record
Terra-Gen has successfully completed several notable projects, including the Edwards Sanborn Solar and Battery Storage Project located in Kern County, California. This expansive project spans 4,600 acres and boasts an impressive solar capacity of 807 MW, along with over 3 GWh of storage, which became operational in phases between 2022 and 2023. The project is capable of supplying up to 1,300 MW to the CAISO grid and was recognized with the 2024 Presidential Federal Sustainability Award (source: cbinsights.com). Additionally, Terra-Gen operates the largest wind farm in the U.S., alongside a portfolio of 26-32 facilities that collectively generate between 2.4-3.9 GW of wind and solar power, complemented by 5.1 GWh of storage capacity (source: terra-gen.com). The company is also actively expanding its operations, with future phases of the Edwards Sanborn project expected to add 2,000 MW of solar and storage capacity, as well as a pipeline of additional wind and solar projects that have been in development since 2020 (source: terra-gen.com).
Recent Developments
In recent years, Terra-Gen has undergone significant changes, including the acquisition of a 50% stake by Masdar from Energy Capital Partners in 2024. This strategic move has enabled the company to expand its operating capacity to approximately 3.8-3.9 GW, including 5.1 GWh of storage across 30 sites, thereby supporting its ambitions for growth in the U.S. renewable energy market (source: terra-gen.com). Additionally, SCOR provided insurance coverage for the Edwards Sanborn project's expansions in February 2025, underscoring the project's importance in California's clean energy transition (source: cbinsights.com). Since 2020, under the management of Igneo Infrastructure Partners, Terra-Gen has successfully added over 1 GW of capacity and 5 GWh of storage, further solidifying its position in the renewable energy sector (source: terra-gen.com).
