Salt River Project’s Navajo Generating Station (NGS) provides electric services to customers across Arizona, Nevada, and California as well as pump water through the Central Arizona project. By upgrading to GE’s newest control platform, the plant benefits from the latest technology and improved life cycle value.
Built in the mid-seventies, Navajo Generating station is a three-unit 2,250 megawatt coal-fired power plant located on the Navajo Nation in Arizona. NGS had retrofitted the original excitation systems with GE’s Ex2000 Excitation systems beginning in 2003. The large exciters represent a significant investment, but the Salt River Project team sought to leverage the benefits of the latest digital control technology to meet its stringent reliability and operational goals, while minimizing cost and installation time.
"The new digital control system and its simple-to-use ToolboxST* software tools are more accurate and dependable, easier to maintain, and—best of all—more efficient, allowing additional kilowatt hours of electricity to be generated each year. The system and software ushers in a new era of power generation for this valuable company asset.”

Wind turbines are becoming established as an economically viable alternative to fossil-fueled power generation. Wind farms consisting of hundreds of units are now adding a significant amount to world generating capacity. As the size of wind farms continues to increase, business economics dictate careful asset management to minimize downtime and maximize availability and profits. A wind turbine condition monitoring system is essential to achieving that goal.
