ArcLight Capital Partners LLC has finalized agreements to purchase 100% of the economic interests in the Middletown Energy Center, a 484 MW natural gas power generation facility located in Butler County, Ohio. The acquisition involves a consortium of sellers and represents ArcLight’s continued investment in power infrastructure, a focus for the firm since its establishment in 2001. ArcLight’s portfolio includes more than 50 power infrastructure investments, establishing a significant history in the North American sector. The Middletown Energy Center, which began operations in 2018, is a relatively new natural gas combined cycle power plant within the PJM market. The plant benefits from favorable natural gas supply and provides dependable power to the PJM market, the largest wholesale electricity market in the United States. Its location benefits from rising electricity demand related to the growth of AI and data centers. "Ohio's emergence as a key location for data centers creates substantial electric infrastructure demands, and Middletown Energy Center, under ArcLight’s management, is prepared to address this need," stated Angelo Acconcia, Partner at ArcLight. This acquisition exemplifies ArcLight's strategy of adding value to electric infrastructure, encompassing power generation, renewables, battery storage, transmission, and digital power solutions. Andrew Brannan, Managing Director at ArcLight, emphasized the plant’s role in providing affordable and reliable power to a market experiencing rapid data center expansion. He highlighted the importance of efficient power generation for regional investment and the vital role of facilities like Middletown. Since 2001, ArcLight has managed over 65 GW of assets and approximately 47,000 miles of electric and gas transmission infrastructure, totaling over $80 billion in enterprise value. With its extensive industry experience and internal resources, ArcLight aims to deliver specialized electric infrastructure solutions to meet the growing demands of AI and data centers, managing the largest private power infrastructure portfolio in North America. The financial details of this private transaction were not revealed, and the deal is expected to close in 2025, pending regulatory approvals.
