Overview
Lake (WY) is a 2.7 MW diesel power plant operated by NorthWestern Energy in Wyoming, USA. It provides backup or peaking power to the local grid.
Lake (WY) is a diesel power plant located in Wyoming, United States, with a capacity of 2.7 MW. Owned and operated by NorthWestern Energy, the facility is currently operational and serves as a small-scale generation source in the region. The plant uses oil as its primary fuel, typical for diesel peaking plants that provide rapid response during periods of high demand or grid instability. Given its small capacity, it falls into the small-scale category for power generation. In the US, such plants are subject to EPA regulations under the Clean Air Act, including emissions standards for diesel engines. As a peaking plant, Lake (WY) plays a role in maintaining grid reliability in the area. Its environmental footprint is relatively low due to limited operating hours, but diesel combustion produces CO2, NOx, and particulate matter. The plant's remote location in Wyoming reduces direct impact on densely populated areas.
Environmental context
The plant's use of diesel fuel results in emissions of CO2, NOx, and particulate matter, though its small capacity and likely intermittent operation limit overall impact. Located in a sparsely populated area of Wyoming, the facility's environmental influence is primarily local. Regulatory oversight under the US Clean Air Act ensures compliance with emission standards for stationary diesel engines.
Frequently asked questions
The Lake (WY) diesel power plant is located in Wyoming, United States, near coordinates 44.4150° N, -110.5739° W.
Lake (WY) is a diesel power plant that uses oil as its primary fuel. It is a small-scale peaking plant with a capacity of 2.7 MW.
The plant is owned and operated by NorthWestern Energy, a utility company serving the region.
Diesel power plants in the US must comply with the Clean Air Act, including emission standards for NOx, SO2, and particulate matter. The EPA's National Ambient Air Quality Standards (NAAQS) and New Source Performance Standards (NSPS) for stationary engines are key regulations.
Small diesel peaking plants provide rapid-start generation to meet sudden increases in electricity demand or to support grid stability during emergencies. They operate only a few hundred hours per year.
