Hydropower Modernization with Advanced Control Systems

By PLCDCSHUB | Power Automation Specialist

Major Hydroelectric Modernization Achievement

Emerson has successfully completed a multi-year automation upgrade project. The initiative modernized four Salt River Project hydroelectric dams in Arizona. These facilities generate substantial renewable energy for the region.

The Roosevelt, Horse Mesa, Mormon Flat and Stewart Mountain dams collectively produce 265 megawatts. This clean power supplies approximately 60,000 Arizona homes annually. The project demonstrates effective infrastructure modernization.

Control System Integration Strategy

SRP implemented Emerson’s Ovation automation platform across all facilities. The system integrated legacy excitation systems with modern distributed controls. This created a unified operational environment.

The standardization enabled seamless communication between systems. Operators gained comprehensive plant visibility. According to IEEE research, such integration typically improves grid reliability by 25-40%.

Measurable Operational Improvements

The modernization delivered significant performance enhancements:

• 30% reduction in operations and maintenance costs
• 50% decrease in troubleshooting time
• 90th percentile unit reliability achievement
• Eliminated startup and shutdown delays

Technical Implementation Details

Engineers installed custom Ovation Excitation Systems at all four dams. Two systems specifically serve pump and energy storage units. These require unique integration during pump mode transitions.

The excitation systems connect seamlessly with existing Ovation distributed controls. This cohesive approach strengthens grid reliability. It also supports increasing renewable energy integration.

Regional Energy Demand Context

Phoenix area growth drives rising electricity consumption. Extreme temperatures further increase power demands. SRP must ensure reliable clean energy delivery.

The modernization project addresses these pressing needs. Enhanced infrastructure supports continuous 24/7 operation. This maintains community power reliability.
