Invenergy, North America’s largest privately held developer, owner and operator of independent power infrastructure, and HA Sustainable Infrastructure Capital, Inc. ("HASI") (NYSE:HASI), a leading investor in sustainable infrastructure assets, today announced the closing of a strategic equity partnership supporting a 2.7-gigawatt portfolio of select Invenergy projects across the United States, including utility-scale solar, solar-plus-battery storage, and wind projects.

Invenergy will retain control and majority ownership and continue to lead day-to-day operations of the projects. The partnership builds on the companies’ longstanding relationship, supports Invenergy’s continued growth, and reflects growing demand for large-scale, contracted clean energy and storage assets.

The portfolio comprises 10 projects totaling 2.7 GW across six major U.S. power markets and seven states: Arizona, New Mexico, Texas, Arkansas, Indiana, Ohio, and New York. More than 850 MW are currently operating, with the remaining projects expected to come online by the first quarter of 2027. HASI will fund each project as it reaches commercial operation. All projects are backed by long-term agreements with investment-grade offtakers, including corporate, utility, and public-sector entities.

CIBC Capital Markets acted as advisor to Invenergy for this transaction. Sidley Austin LLP served as legal counsel to Invenergy, and Baker McKenzie served as legal counsel to HASI in connection with the transaction.

"The transaction with HASI underscores Invenergy’s industry-leading execution abilities and allows us to recycle capital and support the company’s long-term growth," said Meghan Schultz, EVP and Chief Financial Officer. "HASI continues to be a great partner as we continue to deploy power infrastructure that meets the needs of our customers and communities."

"Invenergy is among the most experienced and respected power infrastructure developers in the country, and this portfolio reflects the breadth and quality of its platform," said HASI Chief Client Officer Susan Nickey. "We are proud to build on our partnership with Invenergy through this investment, pairing Invenergy’s development and operating expertise with HASI’s long-term capital solutions to support energy infrastructure across the United States."
