Doreen Diesel Power Plant, Massachusetts | USA Power Generation Facility

Doreen is a diesel power plant located in Massachusetts, United States, with a capacity of 21.1 megawatts. The facility is owned by NAEA Energy Massachusetts LLC and is currently operational. As a diesel-fired plant, it represents a smaller-scale generation asset within the broader U.S. power generation sector. The plant operates under the regulatory framework of the U.S. Environmental Protection Agency (EPA), including the Clean Air Act (CAA) and its National Ambient Air Quality Standards (NAAQS). Diesel power plants are subject to emissions standards for sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter. The facility's age and technology specifics are not detailed, but its capacity suggests it may serve peaking or backup power roles. Its location in Massachusetts places it within a region with diverse energy mix, including natural gas, nuclear, and renewables. The plant's environmental footprint is tied to its oil fuel use, which has higher CO2 and SOx emissions compared to natural gas.

The plant's use of oil as primary fuel results in higher carbon dioxide (CO2) and sulfur oxide (SOx) emissions per megawatt-hour compared to natural gas or renewable sources. Its location in Massachusetts, a state with stringent environmental regulations, means it must comply with state-level emissions limits in addition to federal standards. The relatively small capacity (21.1 MW) limits its overall environmental impact, but diesel plants are often used for peaking power, leading to intermittent operation and potentially higher emissions intensity during startup.
