Texas power plant benefits from advanced water treatment technology

GE's water treatment technology has helped Tenaska Gateway Generating Station in Texas cut costs and reduce its use of water treatment agents.

TREVOSE, PA. May 24, 2013 -- GE's (NYSE: GE) advanced water treatment technology has saved Tenaska Gateway Generating Station, a combined-cycle power plant in Texas, more than $3.2 million in operational expenses and has helped reduce its use of water treatment agents in the past three years.

Located near Mt. Enterprise in Rusk County, Texas, the Tenaska Gateway Generating Station recently incorporated facility enhancements that earned the facility a GE Return on Environment Award. This award recognizes the achievements of industrial users that significantly surpass environmental and industrial operational goals while balancing industrial demands. Tenaska was recognized for its noteworthy reductions in rinse water and water treatment agents.

"Tenaska Gateway Generating Station has a long-time working relationship with GE since before the plant was commissioned, first by employing GE's gas turbine and steam generator technology and more recently, by upgrading our water purification technology. GE's new water treatment equipment enables us to use water more efficiently," said Steve Pearson, plant manager.

In 2010, the existing ion exchange technologies that had been the primary water purifier at the Tenaska Gateway Generating Station were enhanced with the addition of GE equipment utilizing reverse osmosis membrane technology. In addition, GE treats the power plant's water used in the heat recovery steam generators and cooling tower. With GE's water treatment technologies, the plant uses fewer water treatment agents, which helps prevent water quality degradation and the need for additional treatment. It does not need to regenerate the demineralizers as often, which in turn saves money and minimizes the amount of treated wastewater returned to the environment.|

The Tenaska Gateway Generating Station is an 845-megawatt, natural gas-fueled combined-cycle electric generating station. Tenaska, an energy company headquartered in Omaha, Neb., formed Tenaska Gateway Partners, Ltd. to build, own and operate the plant. Affiliates of Tenaska serve as the managing partner and operator. The facility includes three GE Frame 7FA gas turbines, three heat recovery steam generators and one GE steam turbine.
