Origis Energy, a major renewable energy platform in the United States, has secured approximately $545 million in senior secured project financing for three utility-scale solar projects in West Texas. The financing, arranged with Natixis Corporate & Investment Banking and Santander Corporate & Investment Banking, will support the Rockhound Projects totaling around 413 MW of installed capacity in Ector County, Texas, according to a company announcement on March 5, 2026.
All three solar facilities are currently under construction and are expected to commence commercial operations during summer 2026. The projects form part of a larger solar complex in West Texas that will exceed 700 MW upon full completion.
Utility-Scale Solar Projects Expand Texas Renewable Infrastructure
The Rockhound Projects represent the next phase of Origis Energy’s multi-project solar development strategy in the region. The broader West Texas solar complex also includes the Swift Air Solar II and Swift Air Solar III projects, which reached financial close in 2025. Together, these developments will contribute significantly to the state’s renewable energy capacity.
The senior secured credit facilities include multiple components designed to support both construction and operational phases. According to the announcement, the financing package comprises construction loans, term loans, tax credit bridge facilities, and letter of credit facilities.
Banking Partnership Structures Complex Financing
Natixis CIB and Santander served as Joint Underwriters, Coordinating Lead Arrangers, and Co-Green Loan Coordinators for the transaction. Natixis CIB also assumed the role of Administrative Agent, while U.S. Bank National Association acted as Collateral Agent for the financing arrangement.
Alice Heathcote, Chief Financial Officer of Origis Energy, stated that the financing reflects confidence in the company’s ability to execute complex, multi-project transactions. She emphasized that the partnership with Natixis and Santander advances resilient energy infrastructure in Texas while delivering economic benefits to local communities.
Renewable Energy Financing Demonstrates Market Confidence
Andrew Platt, Head of Energy Structured Finance & Advisory US at Santander Corporate & Investment Banking, highlighted the transaction as another milestone in the bank’s partnership with Origis Energy. The financing demonstrates continued institutional commitment to supporting renewable energy platforms across the United States.
James Kaiser, Head of Infrastructure and Energy Finance North America at Natixis CIB, expressed satisfaction with supporting Origis in financing the Greyhound A, Rockhound C, and Rockhound D assets. He noted that both Origis and its backer Antin are important clients to the financial institution.
Legal Representation and Transaction Details
Latham & Watkins LLP represented Origis Energy throughout the transaction, with Reed Smith LLP providing local counsel services. Meanwhile, Milbank LLP represented the lenders, supported by Husch Blackwell LLP as local counsel for the financing arrangement.
The utility-scale solar projects contribute to Texas’s position as a leading state for renewable energy development. However, the state’s grid infrastructure continues to face challenges in integrating large-scale renewable installations while maintaining reliability during peak demand periods.
Origis Energy operates as one of America’s leading renewable energy and decarbonization platforms, focusing on grid-scale power generation, performance optimization, and long-term operation of solar and energy storage assets. The company’s strategic approach emphasizes near-term, cost-competitive solutions for infrastructure needs across multiple markets.
The three Rockhound Projects are scheduled to reach commercial operations by summer 2026, though the company has not provided specific dates for each facility’s completion. The projects’ performance and integration into the regional grid will likely be monitored closely by industry stakeholders and energy regulators.
