Operated by Ameren Missouri, the Taum Sauk Plant is a 440-megawatt pumped storage hydroelectric plant that stores and produces energy for the eastern half of Missouri. This plant uses 1.5 billion gallons of water stored in an upper reservoir to generate clean, renewable electricity and is a critical asset for the power company.
The Taum Sauk Plant provides power during peak demands within their system, but operations declined with aging infrastructure. More than 20 years old and facing obsolescence, the plant’s infrastructure frequently required service and experienced multiple failures.
The Tambak Lorok power plant needed to replace an outdated distributed control system and turned to GE for help.
“We chose the GE solution because it was price competitive, offered the best technical implementation, and provided a wide range of aftermarket services,” explains Mr. Heri Supriyanto, Senior Engineer at Indonesia Power.
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.
