Glenwood Diesel Power Plant | New York, United States

Glenwood is a diesel power plant located in New York, United States, with a capacity of 110 MW. Owned by National Grid Generation LLC, the facility is operational and plays a role in the local power generation mix. Diesel plants like Glenwood are typically used for peaking or backup power due to their ability to start quickly. The plant uses oil as its primary fuel, which results in higher CO2 and SOx emissions compared to natural gas. Under the US Clean Air Act, facilities like Glenwood must comply with NAAQS and may be subject to state-level emission limits. Diesel units often have lower efficiency than combined-cycle plants. Glenwood's location in New York places it within a densely populated region with high electricity demand. The plant supports grid reliability during peak periods or emergencies. Its environmental impact is managed through regulatory permits and emission controls typical for oil-fired generation in the US.

The plant's use of oil as fuel results in significant CO2, SOx, and NOx emissions per MWh compared to natural gas or renewables. Located in New York, it operates in an area with stringent air quality regulations under the US Clean Air Act. The facility's 110 MW capacity places it in the small-to-medium scale for US power plants, and its diesel technology is often associated with higher local air pollutant impacts, especially if located near populated areas.
