Igneo Infrastructure Partners acquires Indigo Generation

New York, November 11, 2025: Igneo Infrastructure Partners (‘Igneo’), a global infrastructure investment manager with US$22.9 billion in assets under management, today announced that it has entered into an agreement to acquire Indigo Generation LLC (‘Indigo’), owner of a 136 MW gas-fired, simple-cycle electric peaking generation station located in North Palm Springs, California.

The project is being acquired from Diamond Generating LLC. Indigo represents Igneo’s inaugural investment in thermal electricity generation infrastructure in the United States, leveraging its deep experience investing in the renewable power sector including though it’s existing portfolio companies Terra-Gen and Soltage.

"Peaking assets in the United States play a valuable role in providing grid reliability and firm dispatchable generation. As a seasoned energy investor, Igneo sees a role for these assets particularly in leveraging their established interconnection, in alignment with our longer-term energy transition thesis,” said John DiMarco, Managing Director at Igneo. "Indigo is ideally situated to capitalize on these trends while providing essential capacity to the local load area. We believe that there is a strong opportunity for value-add investment with the asset at this site.”

Indigo is Igneo’s third investment from its dedicated North American infrastructure strategy, following previous acquisitions in the digital and transportation sectors. Since 2020, Igneo has invested close to US$3.9 billion of capital in the United States. Transaction terms were not disclosed. The acquisition is subject to customary conditions and approvals.

Igneo was advised by Vinson & Elkins LLP on the transaction and National Bank Financial Inc. which acted as its financial advisor.
