Montville Station: Oil-Fired Diesel Power Plant in Connecticut, USA

Montville Station is an operational oil-fired diesel power plant located in Connecticut, United States. With a capacity of 495 MW, it falls into the medium-to-large scale category for diesel power plants in the US. The facility is owned by NRG Montville Operations Inc and plays a role in meeting peak electricity demand in the region. The plant operates under the regulatory framework of the US Environmental Protection Agency (EPA), including the Clean Air Act (CAA) and associated programs such as the National Ambient Air Quality Standards (NAAQS) and the Acid Rain Program. As an oil-fired facility, it is subject to emissions limits for sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter. The plant's technology is typical for diesel power generation, which offers fast start-up and flexibility but has a higher carbon intensity compared to natural gas combined-cycle plants. Montville Station's environmental context includes its proximity to populated areas in southeastern Connecticut. The plant's oil fuel source results in higher CO2 and SOx emissions per MWh compared to natural gas or renewable sources. Its operational role as a peaking or intermediate-load plant means it runs during periods of high demand, contributing to grid reliability but also to local air quality impacts. The facility's age and specific emissions controls are not detailed, but it operates within EPA compliance requirements.

Montville Station's oil fuel type results in higher CO2 and SOx emissions per MWh compared to natural gas or renewable sources. Its location in Connecticut, a state with stringent air quality standards, means the plant must comply with EPA regulations including the Clean Air Act and regional haze rules. The facility's capacity of 495 MW and proximity to populated areas contribute to its potential environmental footprint, particularly during peak operation periods.
