TVA meets winter peak demand record

KNOXVILLE—The Tennessee Valley Authority met a record-breaking winter demand for electricity Friday morning with an estimated 33,345 megawatts when the average temperature across the region hovered at 7 degrees.

This would be TVA’s highest demand for electricity since the summer of 2007 and third-highest in TVA history, a press release said. The previous winter record was 32,572 megawatts set on Jan. 16, 2009.

Meeting the record demand required the combined efforts of TVA’s employees and generating facilities, coordination with the Valley’s 155 local power companies and large industrial customers, and the cooperation of businesses and households to conserve, the press release said.

The release said TVA received 29 percent of its power from coal-fired plants, 21 percent from nuclear plants, 24 percent from natural gas plants, 12 percent from hydroelectric dams, 2 percent from wind farms, and 12 percent from power market purchases. [Read more…]

Power demand hit a peak of 32,460 megawatts at 9 a.m. Tuesday, the second-highest winter peak in Tennessee Valley Authority history.

The preliminary peak power demand occurred when the average temperature in the Tennessee Valley was a frigid 4 degrees, TVA said.

In a press release, the public utility said electricity use is now coming down. [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…]

IDB endorses project to add power at Horizon Center, subject to TVA grant

With a pre-application deadline this Wednesday, the Oak Ridge Industrial Development Board agreed last week to commit $750,000 to a project to increase the electrical capacity at Horizon Center Business Park if the city gets a matching grant from the Tennessee Valley Authority.

The project, which would add 14 megawatts to the park’s electrical capacity with the potential to add more later, would extend power from a substation on Blair Road in west Oak Ridge to the edge of Lot 5 on the back side of Horizon Center. It would install 13 kilovolt lines on poles that could hold 69 kilovolt lines later. [Read more…]

Anyone a Gilbert and Sullivan fan?

“When I was a lad I served a term / As office boy to an attorney’s firm. /
I cleaned the windows and I swept the floor, / And I polished up the handle of the big front door.” (HMS Pinafore)

So, how does this go in Oak Ridge? Perhaps: Oak Ridge National Laboratory’s Carbon Fiber Technology Facility will revolutionize the choice of materials used in manufacturing. Major manufactures, such as auto companies, will be falling over themselves soon to locate here, so as to capitalize on the technical information to be transferred from ORNL (possibly, but it might be a few years out yet). They will all want sites in Horizon Center, next to the ORNL demonstration facility, to be closest to the technology (maybe, but remember that Nissan found a Middle Tennessee location adequate for transfer of battery technology they consider vital to their future).

Carbon fiber manufacturing is a high energy-utilizing process. ORNL’s demonstration facility could take most of the 10-megawatt energy capacity at Horizon Center (true, but Horizon Center was designed as a commercial park, not as an industrial park). So we need a large project to bring 20 megawatts of additional electrical capacity into Horizon Center right away to meet this pressing need (hmm…has there been someone knocking at our doors lately that they have not been telling us about? What we seem to need right now is an incremental project to put in a lesser amount of power, especially at peak load times, so that the one or two parcels we might sell soon at Horizon Center will have adequate power available—else they are correct that nothing might sell).
