ArcLight Capital Partners is acquiring InfraBridge’s 50% stake in a 5.4GW North American thermal power portfolio, partnering with existing owner Invenergy to manage the 11-asset platform.

ArcLight has agreed to buy InfraBridge’s stake in Invenergy AMPCI Thermal Power (IATP) for an unspecified sum.

IATP’s assets include the Grays Harbor Energy Center in Washington, Nelson Energy Center in Illinois, Lackawanna Energy Center in Pennsylvania and St Clair Energy Centre in Ontario.

Sadiq Malik, co-head of InfraBridge, said: “This transaction reflects InfraBridge’s disciplined investment approach and our continued focus on delivering strong outcomes for our investors.

“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.”

Andrew Brannan, managing director at ArcLight, said: “IATP is a unique, diversified, large-scale portfolio of contracted power infrastructure assets which provides significant, low cost power across seven markets.

“We look forward to working with Invenergy, to help drive value from the portfolio and continue to provide grid reliability and resources.”

Angelo Acconcia, president of ArcLight, said: “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.”
