ArcLight Capital Partners has closed its $1.7 billion deal with Brookfield Infrastructure for an additional 25% stake in the Natural Gas Pipeline Co. of America (NGPL) infrastructure system, a source familiar with the deal told Hart Energy on May 13. Brookfield first announced the deal in March.

ArcLight now holds the largest stake in NGPL with a 62.5% interest in the system. Kinder Morgan Inc. remains the operator of the pipeline network with a 37.5% economic interest.

NGPL spans nine states with approximately 9,100 miles of pipeline. The system includes compressor stations capable of 1 million horsepower and 288 Bcf of storage and provides supply to LNG facilities in Texas and Louisiana.

ArcLight manages one of the largest private power infrastructure portfolios in North America. NGPL is a strategic asset that cannot be replicated today, ArcLight Partner Lucius Taylor said in a May 13 press release.

“The U.S. is seeing historic levels of power demand growth, from both electrification and AI, which we believe will continue well into the next decade. Critical infrastructure assets like NGPL will be increasingly necessary to providing both reliability and the ability to help meet the growing infrastructure needs associated with these two investment mega trends,” said Dan Revers, ArcLight’s founder.

Barclays Capital Inc. acted as financial adviser and Latham & Watkins LLP acted as legal counsel to ArcLight on the transaction.
