Danskammer Generating Station is located on the shore of the Hudson River in the Town of Newburgh, New York, United States, 0.5 miles (0.8 km) upstream of the larger oil-fired Roseton Generating Station. Danskammer 'units 1 and 2 burn natural gas as a primary fuel, and oil as a backup fuel (72 and 73.5 MWe nameplate capacity), whereas units 3 and 4 are exclusively fired with natural gas (147.1 and 239.4 MWe nameplate capacity).The station was built by Central Hudson Gas & Electric in the 1950s, and sold to Dynegy in 2001 as part of electricity deregulation. Dynegy sold the plant to Helios Power Capital, LLC in 2013, who in turn sold it to Mercuria Energy Group; Mercuria sold it to Tiger Infrastructure, a private equity firm based on 5th Avenue in New York City, and Agate Power. As of 2018, it is owned by Danskammer Energy, LLC. In 2018, Danskammer Energy filed an application with the New York State Public Service Commission to build a new, larger plant uphill of the current site that would be a more efficient combined cycle facility with an air cooled condenser to reduce water draw, and which would run as a baseload station (able to run all the time), rather than a peaker plant (running just a few hours per week). The peaker plant has been the target of a prolonged environmental lawsuit over its cooling system. The proposed baseload plant is also garnering community protest, as it would increase air pollutants in an already environmentally sensitive area. PFAS chemicals in the water supply of the City of Newburgh have resulted in a residential population which has a lowered immune response and higher cancer risk. Emergency asthma admissions in the City of Newburgh are 2.5 times higher than the New York State Average. As of January 2021, 25 communities have passed resolutions opposing the plant expansion.
