Emerson to modernize Tennessee power plant

Published on: 

Emerson will provide its software and technologies to help modernize the Tennessee Valley Authority (TVA)’s 908 MW Magnolia combined cycle power plant to achieve greater reliability and cleaner electricity.

The Magnolia project is part of TVA’s five-year, $110 million investment to install digital technologies across its power generating fleet. Emerson’s software and technologies will support TVA’s efforts to digitally transform the Mississippi plant through advanced operations, enhanced cybersecurity and digital twin-enabled training.

Reliable, responsible operations are critical to meet the region’s growing power needs. Legacy technologies, which are more expensive and difficult to maintain, present a challenge.


Emerson will replace existing systems at the combined-cycle plant with its “Ovation” automation system and software. Digital twin technologies will provide advanced training to operators, enabling them to respond quickly and safely to power generation demands. Cybersecurity technologies are integral to Emerson’s comprehensive solution that is designed to enhance and secure operations at the Magnolia facility.

The Magnolia project is expected to be completed in 2022. TVA provides power to most of Tennessee and portions of Alabama, Mississippi, Kentucky, Georgia, North Carolina and Virginia. The Magnolia plant, in operation since 2003, generates up to 50% more electricity from natural gas while producing less emissions than other sources.
