Zero Water Discharge Facility

State-of-the-art pollution control equipment used by the Stanton Energy Center enables the plant to operate as a zero-water discharge facility.

The Stanton Energy Center gets most of the water it needs from Orange County’s Eastern Wastewater Treatment Facility. About 10 million gallons of water is pumped to the site each day and eventually evaporated through the cooling towers.

By re-using water that otherwise would end up in the Econlockhatchee River, OUC reduces the demand on our precious groundwater supply. All rain run-off on the site is diverted to holding ponds for re-use.

Groundwater monitoring wells around each pond verify that none of this water leaks into the surficial Aquifer. This water is used in the pollution control process and every day approximately 925,000 gallons eventually evaporate from the tall stacks.

Both Stanton Units I and II were ahead of their time in terms of advanced environmental technology. And both continue to be better than they have to be when it comes to meeting air quality standards. According to federal monitoring agencies, these units are among the most environmentally sound coal-burning operations in the nation. We plan to keep them that way by continuing to modernize with advanced technologies that optimize efficiency, environmental performance and operating flexibility.

Stanton Unit 1

• Began commercial operation in 1987.


• Full generating capacity: 444 megawatts.


• Coal-fired unit equipped with state-of-the-art environmental protection equipment designed to thoroughly cleanse combustion gas before it enters the chimney.


• No measurable impact on the air, according to continuous air quality monitoring.


• Continues to demonstrate superior performance.

Stanton Unit 2

• Began commercial operation in 1996.


• Full generating capacity: 446 megawatts.


• First pulverized coal unit of its size in the nation to use Selective Catalytic Reduction to remove nitrogen oxide — meeting and exceeding all federal regulations for air quality.


• Continues to exceed federal and state environmental requirements.

Stanton A

A combined cycle power-generation facility, Stanton A helps OUC maintain stable power prices by further diversifying our fuel mix and maintaining flexibility through the use of purchased-power agreements.

• Began commercial operation in 2003.


• Full generating capacity: 633 megawatts.


• Combined cycle plant that includes two natural gas-fired combustion turbines, two heat-recovery steam generators and a steam turbine.


• Developed in joint partnership with Atlanta-based Southern Company.


• Features the most environmentally advanced technology available, minimizing emissions and generating electricity 30 percent more efficiently than earlier technologies.


• OUC owns nearly 1/3 of Stanton A's output. The Kissimmee Utility Authority and Florida Municipal Power Agency each owns 3.5%, and Southern Company owns the remaining 65%.
