Origis Lands $545M Financing for West Texas Roundhound Solar Projects

Origis Energy has closed approximately $545 million in senior secured project financing for three utility-scale solar projects in West Texas, advancing the next phase of its growing renewable energy complex in the region. 

The financing, arranged with Natixis Corporate & Investment Banking and Santander Corporate & Investment Banking, supports the Rockhound Projects, a portfolio of solar facilities totaling about 413 megawatts of installed capacity located in Ector County. All three projects are currently under construction and are expected to begin commercial operations in summer 2026. 

Once completed, the broader West Texas complex will exceed 700 MW of generation capacity and includes the Swift Air Solar II and Swift Air Solar III projects, which reached financial close in 2025. 

The senior secured credit facilities include a construction loan, term loan, tax credit bridge financing and letter of credit facilities to support both the development and operational phases of the projects. 

“This financing reflects the quality of the Rockhound portfolio and the confidence our capital partners place in Origis’ ability to execute complex, multi-project transactions with discipline and scale,” said Alice Heathcote, CFO of Origis Energy. 

Natixis CIB and Santander served as joint underwriters, coordinating lead arrangers and co-green loan coordinators for the transaction, with Natixis CIB acting as administrative agent. U.S. Bank National Association served as collateral agent. 

Latham & Watkins LLP advised Origis Energy on the transaction, with Reed Smith LLP acting as local counsel. Lenders were represented by Milbank LLP with support from Husch Blackwell LLP.
