On May 15, 2025, KeyBanc Capital Markets Inc. (KBCM) successfully closed on three facilities totaling $1.3 billion of Senior Secured Credit Facilities (the Facilities) for Doral Renewables’ Mammoth South and Central projects (Portfolio).
The Facilities comprise a $412 million Construction-to-Term Loan, $624 million in Tax Equity and Tax Credit Bridge Loans, and $259 million in Letters of Credit. This transaction will help fund construction of the 1.1 GW Portfolio and serves as the takeout to the KBCM-led bridge financing that closed in August 2024. KBCM acted as Coordinating Lead Arranger, Sole Bookrunner, Administrative Agent, Collateral Agent, and Depositary Agent.
The project is in Pulaski County, Indiana, and along with its sister project, Mammoth North, will form the largest standalone solar portfolio in the U.S. The project includes three utility-scale solar projects: Mammoth South, Mammoth Central I, and Mammoth Central II, totaling 1,128 MWdc. All three have long-term investment grade rated power purchase agreements and are expected to be operational by December 2026. Once operational, the Mammoth Solar portfolio will have a capacity of 1.3 GW and power approximately 275,000 households annually.
This represents the third transaction between Doral Renewables and KBCM.
