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.

A car and house built using large-scale 3D printers at Oak Ridge National Laboratory can provide power to each other, and they’re part of a project designed to answer “what if” questions that could lead to innovations in building and car construction and energy use, storage, and consumption, researchers and officials said Wednesday.

The 210-square-foot house—it’s a solar-powered building—and the printed utility vehicle—officials affectionately call it a PUV—were printed at ORNL’s Manufacturing Demonstration Facility on Hardin Valley Road.

They were unveiled at ORNL on Wednesday during the lab’s first-ever Industry Day. The building and PUV are part of a project called the Additive Manufacturing Integrated Energy, or AMIE, demonstration.

Additive manufacturing is the process used to build something one layer at a time. One of the most well-known examples is the Shelby Cobra car 3-D printed on a large-scale polymer printer at the MDF. President Barack Obama and Vice President Joe Biden admired that vehicle—and joked about taking it for a spin—during a trip to East Tennessee in January. [Read more…]

EPA Green Power Community

Oak Ridge has been recognized as the first Green Power Community in the Southeast by the U.S. Environmental Protection Agency. Pictured above from left during a Monday night Oak Ridge City Council meeting are Oak Ridge Mayor Tom Beehan; Tennessee Representative John Ragan, vice chair of the House Energy Task Force; Robin Manning, executive vice president of external relations for the Tennessee Valley Authority; Marlene Witt, Oak Ridge business office manager; and Oak Ridge Electric Director Jack Suggs.

 

KNOXVILLE—The Tennessee Valley Authority has been recognized as a Top 10 utility leader in green power program sales, and Oak Ridge has been designated the first Green Power Community in the Southeast by the U.S. Environmental Protection Agency.

TVA was recognized by the U.S. Department of Energy’s National Renewable Energy Laboratory. In the first NREL Top 10 ranking in a decade, TVA landed at No. 9 nationally with green power sales of 199,067 megawatt-hours in calendar 2013, thanks to TVA’s Renewable Energy Solutions programs and participating local power companies, a press release said.

Oak Ridge is one of the participating communities, and it received the EPA designation based in part on TVA green power purchases. TVA and Oak Ridge officials had a brief ceremony to celebrate during a Monday night Oak Ridge City Council meeting.

“TVA is proud to be recognized nationally for our strong and growing support of renewable energy,” said Patty West, director of TVA’s Renewable Energy Solutions. “Cost-effective, renewable energy is an important part of TVA’s diverse portfolio of energy-generation sources.”

A key to TVA’s renewable energy sales has been Green Power Switch, or GPS, which TVA launched on Earth Day 2000 with local power companies and members of the environmental community as the first-of-its-kind renewable power purchase program in the Southeast, the press release said. [Read more…]

The City of Oak Ridge is on the verge of being selected by the U.S. Environmental Protection Agency as a Green Power Community, the first in the Southeast, a press release said.

The EPA’s Green Power Partnership is a voluntary program that encourages organizations to buy renewable energy. To be designated as a Green Power Community, a local government must purchase or produce green power in amounts that meet EPA minimum purchase requirements as determined by community electricity usage.

Green power is defined as electricity generated from renewable resources, such as wind, solar, biogas, biomass, and low-impact hydropower. Oak Ridge Electric Department customers can buy Green-e Energy certified renewable energy through the Tennessee Valley Authority’s Green Power Switch program.

To qualify, local governments must also initiate a community-wide green power campaign to encourage renewable energy purchases. The City of Oak Ridge, playing off its nickname as the Secret City due to its historical origins, created a campaign called, “The Secret’s Out: Oak Ridge Loves Green Power,” to encourage residents and businesses to buy green power.

TVA Ed Stephens and Buffalo Mountain Wind Farm

Ed Stephens, program manager for the Renewable Energy Program at the Tennessee Valley Authority, explains the 18 wind turbines at the Buffalo Mountain Wind Farm north of Oliver Springs.

WINDROCK MOUNTAIN—A Tennessee Valley Authority program that allows customers to buy electricity produced by renewable energy sources has generated about one million megawatt-hours—enough to power 68,000 homes, officials said Monday.

TVA considers the innovative Green Power Switch program, the first of its kind in the Southeast when it started 13 years ago, a success story. TVA said the program has helped prevent more than 700,000 tons of carbon dioxide from being emitted into the atmosphere. That’s equal to keeping about 135,000 cars off the road for a year.

And it’s grown from 2,000 customers in 2000 to roughly 12,000 today. That could be because customers today are more aware of environmental concerns and have a greater understanding of their power sources, said Patty West, director of TVA’s Renewable Energy Program. [Read more…]
