Overview
Archer Daniels Midland Mankato is a 6.1 MW coal power plant in Mankato, Minnesota, USA, owned by Archer Daniels Midland Co. It is an operational facility serving industrial power needs.
Archer Daniels Midland Mankato is a coal-fired power plant located in Mankato, Minnesota, United States. With a capacity of 6.1 MW, it is a small-scale facility within the US power generation sector, owned and operated by Archer Daniels Midland Co. The plant is currently operational and supports the energy requirements of the adjacent industrial operations. The plant operates under the regulatory framework of the US Environmental Protection Agency (EPA), including the Clean Air Act (CAA) and its associated programs such as the National Ambient Air Quality Standards (NAAQS), the Acid Rain Program, and the Cross-State Air Pollution Rule (CSAPR). As a coal-fired facility, it is subject to emissions limits for sulfur dioxide (SO2), nitrogen oxides (NOx), and particulate matter. The relatively small capacity suggests it may use older technology, such as subcritical boilers, typical for industrial-scale coal plants. This facility plays a role in providing reliable power to the local industrial site, contributing to the operational stability of Archer Daniels Midland's Mankato operations. Its location in the Midwestern US places it within a region with a mix of coal, natural gas, and renewable energy sources. The plant's environmental impact is managed through compliance with federal and state regulations, though its coal fuel source implies a higher carbon footprint compared to natural gas or renewable alternatives.
Environmental context
The plant's coal fuel source results in significant CO2, SO2, and NOx emissions per MWh, contributing to local and regional air quality concerns. Its location in Mankato, a city with a population of around 40,000, means emissions may affect nearby populated areas. The small capacity (6.1 MW) limits overall impact, but the use of coal without advanced pollution controls (typical for older small plants) could lead to higher emission rates. Regulatory compliance under the EPA's CAA programs helps mitigate environmental harm.
Frequently asked questions
Archer Daniels Midland Mankato is located in Mankato, Minnesota, United States, at coordinates 44.187100, -93.992400.
The plant has a capacity of 6.1 megawatts (MW), making it a small-scale coal power plant.
The plant is owned by Archer Daniels Midland Co, a major agricultural processing company.
The plant must comply with the US Clean Air Act, including NAAQS, the Acid Rain Program, and CSAPR, which regulate SO2, NOx, and other emissions.
Small coal plants often use subcritical boiler technology, which is less efficient and has higher emissions than supercritical or CCGT plants.
