February 2, 2024

Investment manager Nuveen is to join Aiga Capital Partners in providing a $200 million enhanced credit facility to battery storage project developer Spearmint Energy.

Nuveen’s energy infrastructure credit team, which provides private debt and structured equity to assist companies transitioning to a low carbon economy while also ensuring energy security, joins the term loan alongside Aiga, an investment management firm providing capital to North American-based companies developing sustainable infrastructure assets.

The term loan supports the development of Spearmint’s 2.8 GW portfolio of battery energy storage system assets, which includes more than 1GW of projects nearing construction in Texas’ ERCOT power market as well as Revolution, Spearmint’s 150MW / 300 MWh battery storage project in West Texas.

Don Dimitrievich, portfolio manager for Nuveen’s energy infrastructure credit team, said: “We look forward to our partnership with Spearmint Energy in conjunction with Aiga, as Spearmint continues to rapidly expand its enhanced credit facilities. Supporting decarbonisation and best-in-class energy storage operators like Spearmint, which provides critical grid stabilisation to achieve this goal, is a cornerstone of our business.”

Andrew Waranch, founder, president, and CEO of Spearmint, added: “We are excited to welcome Nuveen as a financing partner alongside Aiga as we continue to advance the development of our BESS portfolio nationally. Both Nuveen and Aiga are well known in the renewable energy investing world for distinguishing high growth potential teams and strong project pipelines, and their significant support reflects the success of Revolution to date as well as their confidence in Spearmint’s ability to efficiently construct utility-scale BESS projects key to enabling the renewable energy transition.”

Angel Fierro, managing partner at Aiga Capital Partners, said: “Aiga is excited to partner with Nuveen to support the future growth of Spearmint, a market leader in energy storage. Aiga’s financing has helped scale the company’s development platform and complete the construction of its first 300 MWh project in ERCOT. Nuveen, an experienced and sophisticated energy transition investor, will be a valuable partner to help continue Spearmint’s buildout.”
