Castleton Commodities International (CCI) is in exclusive talks to sell a 196-megawatt (MW) natural gas plant in Pennsylvania, according to two sources familiar with the situation.

The plant, Hunlock Creek Energy, is part of the 2.2-gigawatt (GW) portfolio that Stamford, Connecticut-based CCI was looking to sell in a process led by Lazard, as reported by this news service in November 2025.

CCI decided in March to explore selling the five-power plant portfolio on an asset-by-asset basis as portfolio bids did not meet the company’s price expectations, one of the sources said.

The global energy merchant CCI acquired Hunlock from UGI Energy Services in November 2024 for an undisclosed amount. Macquarie served as the sellside advisor on the process.

The four other assets in the portfolio are the 674 MW New Salem Harbor plant in Massachusetts, the 1.210 GW Roseton Generation Plant in New York, the 79 MW Rensselaer Cogeneration Plant in New York, and the 77 MW Signal Hill Generation Plant in Texas. The portfolio comprises the bulk of CCI’s North American power generation footprint, according to its website.

One of the sources said the portfolio’s prized asset is the New Salem Harbor plant, which went in operation in May 2018 and that CCI acquired in April 2023. The plant is one of the newest, largest and most efficient gas-fired power facilities in New England, according to a press release announcing CCI’s acquisition.

CCI declined to comment and Lazard did not respond to requests for comment.
