Joe Grimes, executive vice president of generation with the Tennessee Valley Authority, gave the keynote presentation during the ELECTRIC POWER Conference and Exhibition, which was held March 19–22 in Nashville, Tennessee. His presentation focused on steps TVA is taking to diversify its generation portfolio in order to reduce risks and keep costs as low as possible for customers.

TVA was created by Congress in 1933. According to its website, TVA was “charged with a unique mission—to improve the quality of life in the Valley through the integrated management of the region’s resources.” As the nation’s largest government-owned power provider, TVA sold more than 152.3 TWh of electricity in fiscal year 2017. Its generation portfolio is 37% nuclear, 24% coal, 20% natural gas, 9% hydro, 3% wind and solar, and 7% energy efficiency.

TVA sells electricity to 154 local power companies and 54 directly served industries and federal facilities. Its power service territory covers 80,000 square miles, including most of Tennessee and parts of Alabama, Georgia, Kentucky, Mississippi, North Carolina, and Virginia.

In this POWER Podcast extra, Grimes speaks with Executive Editor Aaron Larson about TVA’s generation mix and what the future holds for its fleet.
