Pleasant Valley Station

Pleasant Valley Station is a natural-gas fired combustion turbine plant. Its first two units became operational in 2001, and the third in 2002. The power plant uses three large simple-cycle combustion turbines to produce approximately 412 megawatts of electricity on a hot summer day and more than 480 megawatts on a cold winter day.

The station’s primary fuel is natural gas, chosen for its low air emissions and ready availability. The backup fuel is fuel oil. Natural gas is provided to the plant via a Northern Natural Gas high-pressure underground pipeline. Tanker trucks transport the necessary fuel oil to the plant.

The station is located on 150 acres of land near Dexter, Minnesota, and is staffed by 5 skilled operators / technicians who operate and maintain the plant.

How the plant works

Pleasant Valley Station is a state-of-the-art combustion turbine plant. It combusts fuel through a high performance low emission combustion process.

Environmental performance

In 2003, Pleasant Valley Station received International Organization for Standardization 14001 certification of its environmental management system. As a certified plant, Pleasant Valley Station has an environmental management system in place to continuously evaluate and improve environmental performance.
