GenConn Devon LLC - 242 MW Oil-Fired Diesel Power Plant in Connecticut, USA

GenConn Devon LLC is an operational diesel power plant located in Connecticut, United States, with a capacity of 242 megawatts. The facility uses oil as its primary fuel and serves as a peaking plant, providing electricity during periods of peak demand to support grid stability. The plant operates under the regulatory framework of the U.S. 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 peaking plants, which are designed for rapid start-up and flexible operation. GenConn Devon LLC plays a key role in the regional power grid by providing dispatchable generation to meet peak loads. Its location in Connecticut supports the local energy infrastructure, contributing to reliability during extreme weather events or grid emergencies. The facility's capacity of 242 MW places it in the medium-scale range for peaking plants in the United States.

The plant's oil-fired operation results in higher CO2, SO2, and NOx emissions per MWh compared to natural gas or renewable sources. Its location in Connecticut, a state with stringent air quality regulations, requires compliance with regional haze and ozone standards. Proximity to populated areas may increase local air quality impacts, though modern emissions controls can mitigate some effects.
