Analysis

ArcLight Capital Partners has entered into definitive agreements to acquire 100% of the economic interests in the Middletown Energy Center, a 484 MW natural gas-fired power plant located in Butler County, Ohio. The asset, one of the newest and most efficient combined-cycle facilities in the PJM Interconnection, commenced operations in 2018 and has a proven performance track record.

This acquisition reflects ArcLight’s continued strategy of investing in critical power infrastructure, particularly in regions where demand is rapidly growing. The PJM market, the largest wholesale electricity market in the U.S., is experiencing surging power needs driven by the expansion of AI and data center development, especially in Ohio, which is fast becoming a digital infrastructure hub.Angelo Acconcia, Partner at ArcLight, highlighted that Middletown is well-positioned to meet this growing demand: “With increasing demand for digital infrastructure, Ohio has emerged as a premier hub for data centers, and Middletown Energy Center, with ArcLight’s stewardship, stands ready to meet the substantial electric infrastructure needs of this vital sector.”

Backed by over two decades of experience, ArcLight has invested in more than 50 power infrastructure projects since 2001 and currently manages the largest private power infrastructure portfolio in North America. Its portfolio spans power generation, renewables, battery storage, electric transmission, and natural gas infrastructure.

Andrew Brannan, Managing Director at ArcLight, added: “Reliable and efficient power generation is essential to ensuring continued industrial and data center-related investment in the region, and highly efficient resources such as Middletown are vital to these initiatives.”

ArcLight has owned, controlled, or operated over 65 GW of energy assets and 47,000 miles of electric and gas transmission infrastructure, representing more than $80 billion in enterprise value. The acquisition of Middletown adds to ArcLight’s growing footprint in energy infrastructure designed to support digital transformation and electrification trends.

The financial terms of the transaction were not disclosed. Latham & Watkins LLP served as legal counsel to ArcLight. The transaction is expected to close later in 2025, subject to customary regulatory approvals.
