The Tennessee Valley Authority has retired the Bull Run Fossil Plant in Claxton.

The plant burned the last of its onsite coal onsite in August, ending a 48-day run. TVA retired the plant December 1.

The TVA Board of Directors approved the retirement of Bull Run on February 14, 2019. That followed an environmental review process that included public input, TVA said.

Bull Run began operating in 1967. At the time it was the largest in the world in the volume of steam produced, according to TVA. Located on 750 acres in Claxton across from Oak Ridge, it was the only single-unit power plant in the TVA system, and it was designed to produce up to 950 megawatts. It has an 800-foot reinforced concrete chimney.

TVA releases draft power generation plan

The Tennessee Valley Authority has released a draft version of a plan that evaluates its options to meet its power generation needs during the next 20 years, and it is accepting public comments.

Under development since early 2018, the draft of the Integrated Resource Plan was released for public review on Friday.

The Integrated Resource Plan is a power planning roadmap, TVA said in a press release Wednesday. It examines a variety of economic, regulatory, and market-driven scenarios and strategies—both within and outside TVA’s control—to help the public utility respond to changing energy demands while continuing to provide reliable power at the lowest possible cost, the press release said.

“The 2019 IRP emphasizes the importance of flexibility in our generation in response to the changing energy marketplace,” said Laura Campbell, TVA vice president of enterprise planning. “TVA looked at a wide range of possible futures, and flexibility is important in every case to ensure a reliable power supply.” [Read more…]

The coal-burning Bull Run Fossil Plant in Claxton and Paradise Fossil Plant Unit 3 in Kentucky are not economical to operate, and retiring them will offer a savings of about $320 million and avoid more than $1 billion in capital costs, the Tennessee Valley Authority said Thursday.

The TVA Board of Directors voted 6-1 to close Paradise Unit 3 and unanimously agreed to close Bull Run during a meeting in Chattanooga on Thursday. Paradise could close by December 2020, and Bull Run is expected to close by December 2023.

The Bull Run and Paradise closures will be the first 1,700 megawatts of coal plant retirements of the 2,600 megawatts that could be retired through 2033 under a 2015 integrated resource plan, TVA President and Chief Executive Officer Bill Johnson told the board.

Two U.S. Department of Energy national laboratories with energy research expertise, including Oak Ridge National Laboratory, have agreed to pursue research that could find new ways to use coal, a press release said.

ORNL and the National Energy Technology Laboratory in Pittsburgh, Pennsylvania, signed the agreement, a memorandum of understanding, or MOU, on Friday, March 2.

The two labs are joining forces to pursue research on new ways to use coal to create innovative high-value products, the press release said.

U.S. Department of Energy Assistant Secretary for Fossil Energy Steve Winberg attended the signing event.

“The MOU signed today signals the Department’s continued commitment to enhancing the use of our coal resources,” Winberg said. “The depth and breadth of scientific knowledge across the DOE enterprise, especially at our national labs, is what allows for this kind of innovative partnership.” [Read more…]

TVA seeks comment on ‘dewatering’ facility at Kingston, would allow dry storage

Kingston Fossil Plant

HARRIMAN—As part of a commitment to change the way ash and coal products are handled, the Tennessee Valley Authority is proposing to design and build a new facility that would dry out byproduct streams of bottom ash and pyrite at the Kingston Fossil Plant.

The change would allow these coal-burning byproducts to be stored in an onsite, dry landfill.

This project supports TVA’s plan to close all wet ponds containing coal combustion residue and convert them to dry storage throughout TVA’s coal fleet. Kingston is the first of TVA’s fossil plants to undergo the conversion. [Read more…]

Leslie Agron EPA Clean Power Plan Hearing

Oak Ridge resident Leslie Agron testifies at an EPA clean power plan hearing in Atlanta on July 29. (Submitted photo)

Note: This is a copy of testimony given July 29 in Atlanta by Oak Ridge resident Leslie Agron, a write-in candidate in the Democratic primary for Tennessee House of Representatives on Thursday.

Good afternoon, ladies and gentlemen of the EPA. Thank you for taking my testimony.

My name is Leslie Agron. I am from Oak Ridge, Tennessee. As the son of a Manhattan Project scientist, I was born and raised there. I grew up within walking distance of Appalachia.

I am currently a candidate for the Tennessee state legislature. I have previously served on Oak Ridge’s Environmental Quality Advisory Board. I hold an Executive MBA from The Cox School of Business at Southern Methodist University. Given that credential, the thrust of my remarks will be about business and business climate.

I hold that, contrary to industry remarks that coal makes jobs, coal is not good business. To be clear, in a historical sense, coal was very important to the development of America in the 19th and 20th centuries. During those historical times, coal very much enhanced the business climate of our country by supplying affordable energy when no other source of energy was available. [Read more…]

Windrock Memorial: ‘Proud to be a coal miner’s daughter’

Windrock Coal Miners Memorial Unveiling

Family members press forward to find, touch, and take pictures of the names of their loved ones on the Windrock Coal Miners Memorial after it was unveiled Saturday.

 

WINDROCK MOUNTAIN—Today, it’s home to giant wind turbines that tower high above the Tennessee Valley and off-road vehicles that race up and down its gravel roads and steep slopes.

But 50 years ago or more, this mountain a few miles north of Oliver Springs was home to as many as 700 coal miners and their families. The mines have been closed for decades, but the memories have lived on, mostly in fond recollections and old black-and-white photos.

Windrock Miner's Memorial Groundbreaking

Pictured above are Carl Lively, right, who started working in a mine in Windrock Mountain north of Oliver Springs in 1939, when he was 16, and Manuel Tinker, who was born on top of the mountain and later worked in the mines.

Now volunteers are taking action to help preserve the history of the miners and their families. As part of that effort, they unveiled a Windrock Coal Miners Memorial wall on Saturday. It includes the names of more than 1,000 miners who once worked on the mountain.

The red brick-and-granite wall has been under construction for about six months, and several hundred people turned out for Saturday’s dedication ceremony at Lower Windrock at the end of Windrock Road, about three miles from downtown Oliver Springs. Some wept softly as they gently caressed the names of their loved ones on the memorial wall. Others proudly posed for pictures. It was an important day for many.

“It’s one of the greatest things that’s every happened to me, to see this,” said Carl Lively, 91, who started working in the mines on Windrock Mountain in 1939 at the age of 16. “We’re happy as we can be today.” [Read more…]

The Tennessee Valley Authority board of directors recently approved a plan that will retire eight coal units at three plants with more than 3,000 megawatts of combined generating capacity.

The retirements affect all five coal units at the Colbert Fossil Plant in Tuscumbia, Ala.; one of two operating coal units at Widows Creek Fossil Plant in Stevenson, Ala., and two of three coal units at the Paradise Fossil Plant near Central City, Ky. Paradise Unit 3, one of TVA’s largest coal units, will continue to operate.

A number of these units were already idled or scheduled for idling and/or retirement based on an agreement with the Environmental Protection Agency, TVA said in a press release. [Read more…]

Gas and oil deposits in shale have no place to hide from an Oak Ridge National Laboratory technique that provides an inside look at pores and reveals structural information potentially vital to the nation’s energy needs.

The research by scientists at the U.S. Department of Energy laboratory could clear the path to the more efficient extraction of gas and oil from shale, environmentally benign and efficient energy production from coal, and perhaps viable carbon dioxide sequestration technologies, according to Yuri Melnichenko, an instrument scientist at ORNL’s High Flux Isotope Reactor.
