- Brownfield Engine Exchange (BEX) delivers cleaner energy, long-term reliability, improved efficiency and more powerful performance
- Making Energy Greener is one of Siemens’ continuing core focus areas as the global energy landscape evolves and changes
- Over 30 engine exchange projects worldwide to date with several recent new orders
Siemens Gas and Power is focused on helping customers navigate the world’s most pressing energy problems, both for today and tomorrow. Essential applications include providing products, solutions and services that make fossil energy greener. A recent example is a project in Alabama where Siemens is has completed its first large gas turbine section exchange in the U.S. — delivering on that commitment. In this way Siemens is helping make energy greener and more sustainable in an evolving energy landscape.
Earlier this year, Siemens embarked on a project to replace the gas turbine section (V84.2) at PowerSouth’s McWilliams power plant in Covington County, Alabama with a newer, more efficient section that is providing numerous benefits. The newer SGT6-2000E is known for its reliable performance and, in this case, was the perfect, and economically viable, alternative to simply continuing to replace parts and provide maintenance upgrades at regularly scheduled intervals. The McWilliams plant is now equipped with Siemens’ innovative Si3D blades, which are characterized by an aerodynamic design with optimal efficiency.
After the exchange project, the McWilliams plant is now producing 114 megawatts (MW) of cleaner energy, up from an average of 102 MW previously, due principally to improvements in gross simple cycle efficiency from approximately 31 percent to approximately 35 percent. In addition, NOx emissions have decreased from 13-16 parts per million (ppm @ 15 percent O 2) to 10 ppm.
