KNOXVILLE — On Thursday, August 22, the Tennessee Valley Authority’s (TVA) Board of Directors will meet in Florence, Alabama to authorize a 5.25 percent electric power rate increase without any public documentation showing why the increase is needed or how those additional revenues will be spent. This rate increase amounts to approximately a staggering half-a-billion-dollar increase for Tennessee Valley ratepayers. Only in the Tennessee Valley could a major utility raise rates without public scrutiny of financial documents.

The 5.25 percent rate increase coupled with last year’s 4.5 percent electric rate increase is strategically set just below a 10 percent threshold that would trigger renegotiation of hundreds of power supply agreements with local utilities. But even with this rate increase, TVA is still racking up debt at a rate not seen in decades.

Based on documents over a year old at this point, we can only guess what is driving TVA’s current financial woes: the largest buildout of fossil gas in the country this decade. These new fossil gas pipelines and power plants aren’t cheap, and TVA’s plan to increase reliance on gas is risky. Families and businesses across the Valley will see increased bills when gas prices rise again and as these new gas power plants become obsolete in just a few short years.

Solar production and public green space remain options; coal ash questions remain

CLAXTON — Tennessee Valley Authority will demolish most structures at Bull Run Fossil Plant but has not yet shared plans for the ultimate disposition or reuse of the property.

Bull Run Fossil Plant was a coal-fired plant in the Claxton community, located just outside of Oak Ridge in Anderson County, Tenn. The plant opened in 1967. TVA closed it in 2023, and plans to phase out all its coal fired plants by 203.

The utility and its spokesman Scott Brooks have listed the scrubbers, coal handling structures and the large chimney, nicknamed the “lighthouse” by locals, as structures that will likely come down.

TVA has listed some possibilities for the site, including battery storage, park areas, “economic development” and a synchronous condenser, which is a device meant to keep the overall grid's power supply stable without generating any power of its own. This last option would involve keeping and repurposing the turbine building. TVA has not committed to any of these ideas.

Citizens call on TVA to stop passing gas

KNOXVILLE — The Tennessee Valley Authority in coming years plans to add both natural gas and solar plants to its portfolio to meet what it says are rising energy demands.

TVA’s Board of Directors laid out the federal utility’s plan in a meeting at Norris Middle School in May. Environmentalists at a previous hearing criticized the utility’s focus on natural gas rather than renewables or other measures. Other people, largely tied to local power providers, argued that a switch to renewable energy would be unreliable.

TVA showed a map in a press release following the meeting, showing four proposed natural gas plants and two proposed solar plants. Two of those natural gas plants would be in Tennessee while the other two are planned for Alabama and Kentucky. It stated these new plants will total 3,800 megawatts. It also spoke of its System Operations Center, set to open in fall 2024 in Georgetown to manage the utility’s grid. TVA also stated a desire to research nuclear technologies.

“Our region is experiencing growth at six times the national average, which means we must invest in our current power system and build new generation so we can continue meeting our region’s demand,” said TVA president and CEO Jeff Lyash.

Several citizens criticized TVA’s focus on natural gas plants and new pipelines at the listening session May 9. Among them was Clinton resident and activist John Todd Waterman.

GAO report concludes TVA is flat-footed on climate-change risks to infrastructure

This story was originally published by Tennessee Lookout.

WASHINGTON — Extreme weather patterns have sparked several improvements to the climate resiliency of Tennessee Valley Authority electrical infrastructure over the past two decades. 

A report from a government watchdog, however, found the huge utility still has work to do in mitigating climate hazards to the regional power grid. (Bitter cold around Christmas led TVA to implement rolling blackouts).

“TVA has taken several steps to manage climate-related risks,” the Jan. 30 report from the Government Accountability Office said. “However, TVA has not conducted an inventory of assets and operations vulnerable to climate change, or developed a resilience plan that identifies and prioritizes resilience measures to address specific risks.” 

One issue: The Southeast has experienced a period of accelerated warming since the 1960s. Among cities in the region, 61 percent are experiencing worsening heat waves, a percentage greater than anywhere else in the country, according to the GAO. 

The report came in response to a five-part joint request for information on the climate resiliency of U.S. infrastructure, from U.S. Senate Energy and Natural Resources Committee Chair Joe Manchin III of West Virginia and Environment and Public Works Committee Chair Tom Carper of Delaware. The two Democrats sent their request to the GAO on May 13, 2019.
