The Municipal Electric Authority of Georgia (MEAG Power) selected Emerson to modernize and optimize operations at its Wansley Unit 9 combined-cycle power plant.

The 500-MW Wansley natural-gas-fueled power station delivers 69 percent emissions-free power, but obsolete generation controls have impacted the plant’s availability and financial performance. To support the reliability and diversity of MEAG Power’s generation portfolio as it transitions to an even cleaner portfolio, Emerson will upgrade the Wansley Unit 9 control system to a modern, integrated Ovation solution.

Emerson will replace the legacy steam turbine controls, gas turbine controls, and generator excitation, burner management and vibration monitoring systems with a unified Ovation automation platform. Incorporating Emerson’s condition monitoring solution into the control system will translate into greater visibility of asset health. An advanced power application will use predictive model-based control software to optimize operational flexibility and process efficiency by managing steam temperature during load changes created by renewable energy variability.

Robust cybersecurity technologies are vital to Emerson’s solution, which is designed to enhance and secure operations at Wansley Unit 9. The modernization project is expected to be completed in 2022.
