Posted at
By Leave a Comment

The Tennessee Valley Authority will temporarily lower the water level of Melton Hill Reservoir from Sunday, March 24, through Sunday, April 7, to allow property owners to repair docks, stabilize shoreline, and pick up litter, a press release said.

The reservoir’s water level will be held between 790 and 792 feet above sea level—about two to four feet below its current level—during this period, the press release said. The exact rate of the drawdown will depend on weather conditions and may vary with rainfall amounts. Melton Hill will be returned to its normal winter elevation of 794 feet by April 7.

“As in the past, the drawdown targets and dates are subject to change due to weather constraints,” the press release said. “Recent heavy rains could result in greater than usual debris and erosion in some areas.” [Read more…]

TVA releases draft power generation plan

By Leave a Comment

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.

The Tennessee Valley Authority Board of Directors unanimously agreed Thursday morning to close the Bull Run Fossil Plant, a coal-burning power plant in Claxton.

The single-generator plant is across the Clinch River from east Oak Ridge.

In another plant retirement, the board voted 6-1 Thursday to close the one coal-fired generator still operating, Unit 3, at the Paradise Fossil Plant near Drakesboro, Kentucky.

The vote on Paradise was 6-1 on Thursday, with board member Kenneth Allen dissenting.

Paradise Unit 3 could be retired in December 2020, and Bull Run could be closed December 2023, TVA said. Bull Run has been reported to be running at about 30 percent capacity for several years. [Read more…]

Watts Bar Nuclear Plant

The U.S. Nuclear Regulatory Commission announced on Monday that there would be no significant impact from producing tritium for nuclear weapons in a second unit at the Watts Bar Nuclear Power Plant in Rhea County.

The project involves the Y-12 National Security Complex in Oak Ridge.

The tritium could be produced in Unit 2 at Watts Bar, which is near Spring City about 45 miles southwest of Oak Ridge.

Tritium, which boosts the yields of nuclear weapons, is already being produced in Watts Bar Unit 1. The Tennessee Valley Authority has been producing tritium there since 2003.

The Tennessee Valley Authority confirmed Wednesday that 2018 was the wettest year in the Tennessee Valley in 129 years of record keeping.

There was a basin average of 67.1 inches of rain across the Tennessee Valley in 2018, TVA said.

The previous record was 65.1 inches in 1973.

The TVA rain gauge on Mt. Mitchell in North Carolina received 118.8 inches of rain in 2018.

The Tennessee Valley region normally averages 51 inches of rain a year. [Read more…]

A record amount of rain has fallen in the Tennessee River Valley in 2018, and the year isn’t over yet. The rain might not be either.

The previous record of 65.1 inches of rain was set in 1973. The record, based on 129 years of weather data, was announced by the Tennessee Valley Authority on Friday.

“As 2018 draws to a close, yearly rainfall totals for the TVA region continue to climb to near record levels, and the trend for above average rainfall totals continues right up to year’s end,” the public utility said.

“For the week before Christmas, rainfall averaged two inches in the eastern Valley and 1.4 inches in the western Valley,” said James Everett, senior manager for TVA’s River Forecast Center. “We began spilling and sluicing at several locations the day after Christmas to increase flows and increase flood storage capacity, and that will likely continue into the New Year.” [Read more…]

Note: This story was last updated at 4 p.m.

The earthquake near Decatur early Wednesday morning was felt in Oak Ridge, according to social media reports. Oak Ridge Today readers reported feeling the earthquake in other communities such as Clinton, Hardin Valley, Harriman, Oliver Springs, Sevier County, and Atlanta.

The 4.4 magnitude earthquake was also felt in other areas across the Southeast, including in Tennessee, Georgia, and North Carolina.

Some people in the region described it as like a train or truck driving by, and they said homes shook, and doors and windows rattled. Some said it woke them up, and others said they didn’t feel it. (Oak Ridge Today did not feel it.)

The earthquake was reported about nine kilometers underground at 4:14 a.m., according to the U.S. Geological Survey. The epicenter was 11 kilometers north-northeast of Decatur. Oak Ridge is about 45 miles northeast of Decatur.

It was reported to be the largest in Tennessee since a 4.7 magnitude earthquake in Maryville in 1973 and the second strongest on record in East Tennessee. The Maryville earthquake 45 years ago was the strongest in East Tennessee. [Read more…]

TVA asks for public input on closing Bull Run, Paradise fossil plants

The Tennessee Valley Authority is asking for public input on a review of the potential environmental and socioeconomic impacts of closing the Bull Run and Paradise Fossil Plants.

Bull Run, located in Anderson County, Tennessee, is a single-generator coal-fired power plant. Paradise, near Drakesboro, Kentucky, has one coal-fired generator still operating, unit 3. Two other coal-fired units at Paradise were retired when a new natural gas plant began operation at the site in 2017.

TVA announced a review of generating assets that was focused on Bull Run and Paradise in August. The review is based on the future cost of maintenance and environmental compliance, and other factors. TVA said it must continually evaluate its fleet to ensure flexibility and financial responsibility.

Oak Ridge Today reported when the review was announced in August that the evaluation could help determine whether the plants will be needed in the future. The assessment is to focus on plants that are the least efficient, least cost-effective, and expected to have the highest future costs, TVA spokesperson Scott Brooks said. Plants that fit into that category are the Bull Run Fossil Plant, the one remaining unit (Unit 3) at the Paradise Fossil Plant in western Kentucky near Drakesboro, and combustion turbines (gas turbines), Brooks said. The assessment will look at whether TVA needs Bull Run or Paradise or combustion turbines in the future. [Read more…]

The Tennessee Valley Authority and the U.S. Fish and Wildlife Service have reached a multi-agency agreement to provide continued funding for three federal fish hatcheries that have stocked waters in Georgia and Tennessee with millions of trout.

The partnership, which began in 2013, includes the Tennessee Wildlife Resources Agency and the Georgia Department of Natural Resources.

Since 2013, TVA has been funding trout production by the Service at three national fish hatcheries: Dale Hollow and Erwin in Tennessee, and Chattahoochee Forest in Georgia. The trout are then provided to the following tailwaters: Apalachia (Hiwassee River), Blue Ridge, Boone, Cherokee, Fort Patrick Henry, Normandy, Norris, South Holston, Tims Ford, and Wilbur. Trout-stocked reservoirs in the plan include Fort Patrick Henry, South Holston, Parksville, Watauga, and Wilbur reservoirs.

The four partner agencies announced the new agreement Tuesday at a press conference beside the Clinch River below Norris Dam. The agreement provides partnership funding through fiscal year 2021, a press release said. [Read more…]
