Roseton Generating Facility is a dual-fuel natural-gas- and fuel-oil-fired steam power plant located at 992 River Road in the Town of Newburgh, Orange County, New York, on the west shore of the Hudson River. Both units are capable of firing No. 6 fuel oil and natural gas as primary fuels, with natural gas or No. 2 fuel oil as ignition fuels. The facility operates two GE 3,600-RPM steam turbine generators, supplies power into NYISO Zone G, and includes an auxiliary natural-gas-fired boiler and emergency diesel generators. The plant interconnects at 345 kV to the Central Hudson Gas & Electric transmission system. Roseton Generating LLC is the current owner and operator as of 2026.

  The New York State Department of Environmental Conservation (NYSDEC) issued a decision renewing and modifying the State Pollutant Discharge Elimination System (SPDES) permit for Roseton Generating Station. The decision confirmed continued operation of the facility with once-through Hudson River cooling, replacement of two traveling screens with conventional vertical traveling screens, and fuel-oil containment improvements. The record shows the facility had a substantially lower capacity factor in 2014-2016 (average 3.63%) than in 2003-2005 (average 33.02%).

- 2026-07-01 — PowerTransitions announces agreement to acquire Roseton Generating Facility; transaction pending
  PowerTransitions announced that it has entered into an agreement to acquire the 1,242 MW Roseton Generating Facility in Newburgh, New York from a subsidiary of Castleton Commodities International LLC. PowerTransitions describes Roseton as a dual-fuel natural gas-fired power plant that has supplied power into NYISO Zone G since 1974. The company states that the facility's scale and existing grid infrastructure make it an ideal candidate for co-location development into a robust energy campus, including potential new energy storage systems. The acquisition was described as pending as of July 25, 2026.

## Data quality

- The facility consists of two units each with 621 MW nameplate capacity per EIA 860 data, totaling 1,242 MW, which is the most recent and consistent figure. The 2013 New York regulatory record (PSC Case 13-E-0019) authorized retirement before expiration of the notice period but does not establish that the facility was actually retired. Subsequent permit renewals, operational records, and the 2026 acquisition announcement confirm continued operation. The 2026 NYSDEC draft permit explicitly states that it would allow continued operation of existing infrastructure without new, expanded, or modified operations. Any prospective repowering, replacement, or energy-campus development is outside the scope of the current facility description and must remain distinct in future records. These are separate financial transactions. PowerTransitions announced an agreement to acquire Roseton on July 1, 2026, with the transaction described as pending as of July 25, 2026. No closing date is documented; the acquisition is not yet complete. The facility is served by Central Hudson Gas & Electric Corporation as transmission owner. The predecessor ownership included Central Hudson, Niagara Mohawk Power Corporation, and Consolidated Edison; all divested in 2001 to Dynegy, which subsequently sold to CCI in 2013. The NYSDEC notice identifies Roseton Generating LLC at address 811 MAIN ST STE 3500 HOUSTON, TX 77002 as the applicant and operator, consistent with corporate registration of the entity. Actual annual generation has historically been low relative to nameplate capacity. The 2019 NYSDEC record documents a capacity factor of 3.63% in 2014-2016, compared to 33.02% in 2003-2005, indicating significant operational variation.
