Audio By Carbonatix

NEW YORK & BOSTON--(BUSINESS WIRE)--Mar 12, 2026--

InfraBridge, a leading global infrastructure manager and a division of DigitalBridge Group, Inc. (NYSE: DBRG), and ArcLight Capital Partners (with its affiliates, “ArcLight”), a leading infrastructure investor with a long-standing focus on critical electrification infrastructure, today announced the signing of a definitive agreement for ArcLight to acquire InfraBridge’s 50% stake in Invenergy AMPCI Thermal Power (“IATP”), a jointly owned power portfolio in which Invenergy will retain its existing ownership interest and operational role.

IATP is a large-scale, diversified portfolio of 11 power infrastructure assets located across North America, including several highly efficient combined cycles: Grays Harbor Energy Center in Washington, Nelson Energy Center in Illinois, Lackawanna Energy Center in Pennsylvania, and St. Clair Energy Centre in Ontario. The assets are owned in partnership with Invenergy, North America’s largest privately held developer, owner, and operator of independent power infrastructure.

“This transaction reflects InfraBridge’s disciplined investment approach and our continued focus on delivering strong outcomes for our investors,” said Sadiq Malik, Managing Director, DigitalBridge and Co-Head of InfraBridge. “We are proud of our longstanding partnership with Invenergy and the performance of the IATP portfolio. ArcLight brings deep experience across North American power markets, and we are confident the business is well-positioned for its next phase of ownership.”

"IATP is a unique, diversified, large scale portfolio of contracted power infrastructure assets which provides significant, low cost power across seven markets,” said Andrew Brannan, Managing Director at ArcLight. “We look forward to working with Invenergy, to help drive value from the portfolio and continue to provide grid reliability and resources.”

"We believe that strategic power portfolios like IATP, which provide significant capacity, reliability and grid infrastructure across North America, will play an increasingly critical role in helping to meet the power demand needs driven by AI and electrification," said Angelo Acconcia, President of ArcLight.

Financial terms of the private transaction were not disclosed. The transaction is subject to customary regulatory approvals and other closing conditions and is expected to close in the second half of 2026.
