Fusion research, natural gas, solar power and battery improvements at heart of TVA’s plans to wean itself off coal

OAK RIDGE — The Tennessee Valley Authority is phasing out coal and announcing developments tied to other energy sources at two plants that sit on either side of Oak Ridge.

One of the options includes a fusion test site. Scientists have long pursued fusion energy, though the technology remains in infancy and has yet to generate electricity anywhere.

The TVA coal plant on Edgemoor Road in the Claxton community in Anderson County closed Dec. 1 last year. TVA remains uncommitted to any plans for most of the land around the plant. A company recently announced, however, that it plans tests connected to fusion power in a small part of one of Bull Run’s old buildings by 2028. It will be an experiment and not generate power directly.

Meanwhile, TVA plans to retire Kingston Fossil Plant on Swan Pond Road in Harriman by the end of 2027. Its nine coal-fired units power about 818,000 homes. To replace the power generated at the plant, TVA plans to build a new complex at the Kingston plant’s site, combining natural gas, solar power and battery storage.

TVA plans to retire all its coal plants by the 2030s.

The Tennessee Valley Authority plans to retire the Kingston plant and its four other remaining coal-fired power plants by 2035.

But it is seriously considering replacing them with large fossil gas power plants and new gas pipelines!

Natural gas is cleaner than coal, but is yet another fossil fuel source that releases carbon dioxide. Such a replacement would be contrary to the national and global consensus that we must reduce the use of fossil fuels quickly to constrain the runaway climate crisis as much as we can.

A plan based on emerging technologies for increased energy efficiency combined with distributed use of renewable energies and energy storage can increase community resilience; create more good, long-term jobs; diversify local business opportunities; and provide immediate public health benefits.

TVA accepts public comments electronically through the end of July 15, 2021. 

Don’t miss the opportunity to tell TVA that customers don’t want to pay for a yesteryear “solution” that does not really address the clear and present dangers to humanity. The Southern Alliance for Clean Energy has made it easy for you:

PV Magazine & BO Klima: Berlin macht Solardächer zur Pflicht

The rooftop solar law, passed on June 16, says every new building and substantial renewal of an existing building’s roof must be equipped with solar panels covering at least 30 percent of the roof surface.

The German capital — which is on the same latitude as Labrador City — intends to become more climate friendly. It wants to act as a role model for other municipalities and states in how to accelerate the energy transition. It aims for solar to cover 25% of its electricity consumption.

The city contends, the solar potential of its roofs has gotten inadequate consideration and expects the new law will create many future-proof jobs in planning and trades.

Building owners may opt to use solar facade panels or contract with third parties to build and operate equivalent solar capacity that fulfills the mandate elsewhere in the city. But critics of the law say it does not address how to optimize its implementation with present practices, regulations, and tariffs. They predict, this law will be inefficient and costlier than other methods to stimulate renewable energy generation.

Bavaria, for example, launched an incentive program that awards combined new solar and battery storage installations. Applications for that program have multiplied quickly and now are deemed likely to surpass the 100,000 installations mark by the end of its third year.

Germany, whose entire southern border is farther north than Quebec City or Duluth, has a long history of technology and policy leadership in renewable energies. In 1991 the German Electricity Feed-in Act was the first in the world that mandated grid operators to connect all renewable power generators, pay them a guaranteed feed-in tariff for 20 years and prioritize these sources.
