Mount Sinai South Nassau Diesel Power Plant | New York, USA

Mount Sinai South Nassau is a diesel power plant located in New York, United States, with a capacity of 2.9 MW. The plant is owned by South Nassau Communities Hospital and is currently operational. As a small-scale diesel facility, it serves primarily as a backup or emergency power source for the hospital, ensuring continuity of critical operations during grid outages. The plant operates on oil as its primary fuel, a common choice for emergency generators in the healthcare sector. In the United States, diesel power plants are regulated under the Clean Air Act (CAA), including National Ambient Air Quality Standards (NAAQS) and emission limits for criteria pollutants such as SOx, NOx, and particulate matter. The facility's small capacity places it in the lower tier of power generation, typically subject to less stringent permitting requirements compared to larger utility-scale plants. Mount Sinai South Nassau plays a critical role in ensuring energy reliability for the hospital, supporting patient care and safety during emergencies. Its location in a densely populated area underscores the importance of compliance with local air quality regulations. The plant's operational status contributes to the resilience of the healthcare infrastructure in the region.

The plant's use of oil as fuel results in higher CO2, SOx, and NOx emissions per MWh compared to natural gas or renewable sources. Its location in a populated area near Long Island may raise local air quality concerns, particularly under the US EPA's NAAQS. The small capacity (2.9 MW) limits its overall environmental footprint, but diesel generators are often subject to emission standards under the Clean Air Act to mitigate impacts on nearby communities.
