On May 2, 2025, LSP-Cottage Grove, L.P., successfully closed a $165.9 million refinancing for the Cottage Grove Cogeneration facility, a 265 MW combined-cycle gas turbine (CCGT) plant located in MISO Zone 1. The recapitalization was executed via an issuance of $125.9 million in senior secured notes and a $40 million letter of credit facility.
The 18-year financing is supported by a recently executed 15-year tolling agreement with a leading regional cooperative utility. Cottage Grove is a critical source of local capacity in MISO with an impeccable safety record, having recently achieved 10,000 days without a lost time accident. The dual-fuel facility can provide continuous power to the MISO grid during system emergencies while simultaneously supporting the operations of a major North American chemicals and manufacturing company through the provision of industrial energy products. Furthering the plant's reliability benefits, Cottage Grove's affiliate, Cottage Grove Storage, is progressing the development of an advanced-stage 80 MW / 320 MWh energy storage project at the facility's site.
Global Infrastructure Partners (GIP), a part of BlackRock and PGIM Private Capital were the purchasers of the notes and Mizuho acted as LC issuing bank. White & Case LLP served as counsel to the issuer and Morgan Lewis & Bockius LLP served as counsel to the purchasers and LC issuer. PEI Global Partners served as exclusive financial advisor to the issuer on the transaction LSP-Cottage Grove, L.P., which is wholly owned by funds managed by Ultra Capital, LLC and Littletown Holdings LLC, an entity owned by the management team of Panamint Capital LLC, and receives Management Services from Panamint Capital.
“We are pleased to have closed this financing with GIP, PGIM Private Capital and Mizuho, underscoring Cottage Grove's essential role in the region's energy landscape. This recapitalization, leveraging a long-term contract with a high-quality counterparty, validates Panamint's investment thesis from 2021. We remain committed to strategic investments that support the plant's reliability and ongoing battery storage expansion.”Kristian Hanelt, Partner at Ultra Capital
“The transaction is a great result for our investors in this deal and for our team, who demonstrated Panamint's commitment to delivering high quality outcomes by executing this complex financing,” said Apolka Totth, Chief Executive Officer of Panamint Capital. “Over four years we have taken Cottage Grove from an underinvested asset to an investment grade-rated facility with best-in-class operations. We are excited to deepen our relationship with GIP, PGIM Private Capital and Mizuho and look forward to managing Cottage Grove through its next phase of success and facility expansion.”Panamint Capital
