ArcLight's Strategic Acquisition of Middletown Energy Center



On July 10, 2025, ArcLight Capital Partners, LLC announced an important development in its investment strategy, having entered into definitive agreements to acquire 100% of the economic interests in Middletown Energy Center, a highly efficient natural gas-fired power generation facility located in Butler County, Ohio. With a capacity of 484 MW, Middletown is recognized as a top-tier asset in the PJM market.

This acquisition marks another milestone in ArcLight's ongoing commitment to the power infrastructure sector, a field it has been actively investing in since its establishment in 2001. Over the years, the firm has successfully completed over 50 power infrastructure investments, showcasing a long-standing and robust track record within North America.

Middletown began operations in 2018, positioning itself as one of the newest natural gas combined cycle power plants within the PJM market. Its advantageous access to gas supply allows it to efficiently provide reliable and dispatchable power to the largest wholesale electricity market in the U.S.. Notably, the facility has a strong operational history, and its location signifies considerable demand growth due to the rising electricity needs stemming from advancements in artificial intelligence and data centers.

Angelo Acconcia, a Partner at ArcLight, commented on the strategic relevance of this acquisition, noting that Ohio is fast becoming a hub for data centers driven by increasing demand for digital infrastructure. He emphasized that the Middletown Energy Center, under ArcLight's management, is well-equipped to address the substantial electric infrastructure requirements of this burgeoning sector.

Andrew Brannan, Managing Director at ArcLight, expressed confidence that Middletown will play a vital role in providing consistent and affordable power necessary for facilitating industrial investments and supporting the rapid expansion of data centers in the region. He argued that dependable and efficient power generation is essential to encourage sustained growth in industrial activities.

Since its founding, ArcLight has either owned, controlled, or operated more than 65 GW of assets and 47,000 miles of electrical and gas transmission infrastructure, amounting to an impressive $80 billion of enterprise value. The company brings deep industry expertise and comprehensive support services, positioning it well to meet the critical demands of AI and data center power requirements. With this acquisition, ArcLight continues to manage the largest private power infrastructure portfolio in North America.

The financial specifics of the acquisition remain undisclosed, though the transaction is anticipated to close in 2025, pending regulatory approvals. Latham & Watkins LLP is serving as legal counsel for ArcLight, underscoring the thorough approach the firm employs in its strategic investments.
