“Our intelligence and flexibility as a society will be tested as the financial and industrial giants all figure out what they’re going to do.”
The Tennessee Valley Authority intends to phase out its aging fleet of coal plants by 2035, potentially replacing the age-old carbon-rich power source with increased use of natural gas and refreshed, concentrated supplies of nuclear energy as the vast utility moves to drastically reduce its greenhouse gas emissions.
The plan emerged Wednesday, about a month after the Biden administration called on the U.S. power sector to eliminate pollutants linked to climate change by 2035.
The Tennessee Valley Authority is the largest public provider of electricity in the United States. It provides wholesale power to every major municipal provider in Tennessee, as well as other metropolitan areas and smaller utility districts and cooperatives within its seven-state service area.
Coal represents 14 percent of TVA’s energy portfolio. Its other main fuel sources are nuclear (41 percent) and fossil gas (27 percent). Hydropower accounts for 13 percent of its generation, with solar, wind and efficiency programs making up only 5 percent of its current power portfolio, according to the Knoxville-based Southern Alliance for Clean Energy.
The consequential plan was introduced almost off-handedly on Wednesday by TVA President and CEO Jeff Lyash, who appeared with West Virginia Sen. Joe Manchin during a live online international energy discussion hosted by the Atlantic Council, a bipartisan global think tank.
The TVA plan as announced during the webinar was first reported by the Chattanooga Times Free Press, and then relayed locally on Friday by Knoxville Compass. The Lyash and Manchin quotes and descriptions below were derived from the recorded seminar or a TVA transcript of the event passed to Hellbender Press by Compass.
Two TVA spokesmen didn’t respond to requests for comment on Friday.
Mayor wants green for green; some otherwise supportive city residents already aren't pleased with some initiatives.
Mayor Indya Kincannon's proposed Knoxville 2020-2021 budget commits some $30 million to reduce city climate impacts, expand its use of renewable energy, invest in urban forest preservation and outdoor recreation assets and improve bus and bicycle travel in communities across the city. The budget also provides money for revitalization of the Burlington District, a historic pedestrian center of Black commerce in East Knoxville.
The city's net budget is $384 million, which includes a $253 million operating fund.
The budget is just a recommendation to City Council at this point.
Last year, Knoxville Utilities Board committed to supplying 20 percent of its electricity through solar generation by 2023, through Tennessee Valley Authority’s (TVA) Green Invest program. By 2023, KUB will provide 502 megawatts annually of new-to-the-grid solar power to its customers. This represents the equivalent of enough energy to power 83,000 homes. The $1.63 million cost will be paid by a credit provided by TVA as part of its 20-year partnership agreement with KUB.
The announcement was celebrated by solar energy advocates, including the Tennessee Solar Energy Industries Association, but some environmental watchdogs maintain there are issues with the contracts that local power companies had to enter into with TVA to participate in Green Invest.
For the past few years, TVA sought 20-year rolling contracts with local power companies. KUB’s previous contract with TVA was for five years. In August 2019, TVA presented the Knoxville Utilities Board with a 20-year contract that would provide a credit of 3.1 percent on wholesale base rates and flexibility to allow up to 5 percent of KUB power to come from local sources.
Stephen Smith, who holds a doctorate in veterinary medicine from the University of Tennessee, has served as the executive director of the Southern Alliance for Clean Energy (SACE) since 1993. Founded in 1985, SACE promotes responsible energy choices in the Southeast.

“Any time solar is being built, that’s a positive thing,” Smith said. But, he added, “It’s important to put it into context. What has [KUB] given up by entering into what we consider a Draconian contract?”
