Tolk Generating Station

Tolk Generating Station

This is a coal-fired, steam-electric generating plant


Location: East of Muleshoe, Texas.

Plant Description: Tolk Station is a coal-fired, steam-electric generating station, with two operating units.

Power Production Capabilities: 1,065 megawatts (MW): Unit 1 – 540 MW and Unit 2 – 540 MW

Fuel Source: Low-sulfur coal supplied primarily from Wyoming’s Powder River Basin.

Plant History

 Unit 1 was completed in 1982, and Unit 2 in 1985

Interesting Features

The station is named after Roy Tolk, who was president and chairman of the board when Southwestern Public Service Company (one of the predecessor companies to Xcel Energy) decided to build coal-fueled plants. Coal for the plant is unloaded from rail cars at a “rotary dump,” which rotates each railcar upside down to empty it of coal.

Environmental Highlights

Tolk Station is one of our cleanest performing generating plants. Plant X is one of our cleanest-performing generation plants. In fact, our Energy Supply department awarded the Plant X-Tolk Generating Station complex its environmental traveling trophy for several years of exceptional environmental performance with air, waste, and water.

Air emissions are controlled at Tolk Station with the help of low-sulfur coal and baghouses. Baghouses act like giant vacuum cleaners, removing particulate emissions from the flue gas by more than 99 percent. The particulate or ash collected at Tolk is recycled as byproducts for construction, oil well “mud,” and other uses rather than sending it to a landfill. Tolk Station is a “zero discharge” plant, which means no process waters are discharged off-site.

Operating in an arid region, we have developed a unique solution to reduce water supplies at two of our facilities, Tolk Station and nearby Plant X. By creating a pipeline to send Plant X blowdown water (used water from plant operations) for recycling and additional fresh water to Tolk Station for treatment, we increased water recovery from Plant X, and eliminated the need for new sludge and disposal ponds and a wastewater treatment system at the facility. As a result, the combined plants’ water consumption was reduced by about 180 million gallons per year.

Community Involvement

Tolk Station is a strong supporter of the local United Way.  Employees from the plant are also involved with volunteer fire departments and EMS departments as well as Women in Science Endeavors (WISE), Rotary, 4-H, and Meals on Wheels.
