Alexander to TVA: Don't Buy Wind Power

Posted By on Thu, Mar 23, 2017 at 2:11 PM


Tennessee Sen. Lamar Alexander urged Tennessee Valley Authority (TVA) board members on Wednesday not to buy electricity from a proposed project that would bring wind energy here from Oklahoma and Texas.

Clean Line Energy Partners want to build a $2 billion wind-energy network (called the Plains and Eastern Clean Line) that would begin with wind farms on the plains of Oklahoma and Texas and end in converter stations in Pope County Arkansas and Millington, Tenn. Between the two points would be 720 miles of overhead electrical lines.

Alexander took to the Senate floor Wednesday to tell TVA board members that buying that renewable energy would raise energy rates here.

"A contract with Clean Line Energy Partners could cost TVA ratepayers more than $1 billion over the next 20 to 30 years, the typical length of such an agreement," Alexander said in a floor speech. "TVA would be disregarding its mission to provide low-cost power to the region if it were to contract for power the region doesn’t need, regardless of the source of electricity."

Alexander further criticized the project, noting it would come with "giant, unsightly transmission towers" that would "carry comparatively more expensive, less reliable electricity to Tennessee and other southeastern states."

Also, Alexander criticized the project because it involves the use of federal eminent domain "over the objection of the state of Arkansas and both the state’s senators to acquire the land necessary for the transmission line."

Alexander said Clean Line and its supporters have urged the TVA to agree to a long-term power purchase agreement. He said that's because federal subsidies for wind power end after 2019.

However, Alexander called it a "big, expensive decision" and should not be made quickly.

"So last December, I wrote to TVA saying 'there should not be a rush to approve any proposal from Clean Line Energy Partners," Alexander said.

Further, Alexander said TVA doesn't need to buy anymore power, citing a TVA statement. For more evidence, he pointed to the fact that the agency recently sold its unfinished Bellefonte Nuclear Power Plant.

"So why would TVA announce that it doesn’t need new power for the next 15 years, sell a nuclear power plant capable of producing reliable baseload power for the next 60 years, and then turn right around and buy unreliable wind power that might only be available for 20 or 30 years assuming the turbines don’t break down?" Alexander asked.

He said TVA is on the "right path," pointing to many projects including the under-construction, $975 million natural gas plant in Memphis.

Sen. Alexander’s full remarks are below:

Today I come to the floor to express once again my opposition to the possibility that the Tennessee Valley Authority (TVA) might raise our electric bills and waste more than $1 billion buying electricity the region does not need by agreeing to purchase power from the Clean Line Energy Partners’ proposed Plains and Eastern wind power transmission project.

Congress has a responsibility to conduct oversight of TVA’s decisions and also ensure that TVA is fulfilling its mission as defined by the TVA Act.

Although TVA does not receive any federal funding from Congress, TVA is a federal corporation and its Board members are nominated by the president and confirmed by the Senate.

The House Transportation and Infrastructure Committee and the Senate Environment and Public Works Committee, the Committees responsible for oversight of TVA, have held hearings to discuss TVA’s budget and policies.

So as a United States Senator, I’m here today to exercise my oversight responsibilities.

Clean Line Energy Partners, a Texas-based company, is proposing to build giant, unsightly transmission towers from Oklahoma through Arkansas to Tennessee – known as the Plains and Eastern Clean Line – to carry comparatively more expensive, less reliable electricity to Tennessee and other southeastern states.

For the first time ever, federal eminent domain will be used – over the objection of the state of Arkansas and both the state’s senators – to acquire the land necessary for the transmission line.

In order to move forward with construction of the single 700-mile high voltage direct current transmission line, Clean Line Energy Partners must find utilities in the southeast willing to purchase the power produced by an Oklahoma wind farm and transmitted by the Plains and Eastern Clean Line.


TVA would be disregarding its mission to provide low-cost power to the region if it were to contract for power the region doesn’t need, regardless of the source of electricity.

In recent years, according to TVA, power demand throughout the Tennessee Valley has declined.

In 2013, TVA began working with its customers to develop a long-term plan to meet the region’s power needs through 2033.

In 2015, when TVA completed its Integrated Resource Plan, that plan concluded “there is no immediate need for new base load plants after Watts Bar Nuclear Unit 2 comes online and uprates are completed at Browns Ferry Nuclear Plant.”

As a result of this conclusion, because TVA did not need the power, TVA decided last year to sell the unfinished Bellefonte Nuclear Power Plant.

For the foreseeable future, TVA has said it doesn’t need any new baseload power and does not plan on any major capital construction projects.

This is good news for ratepayers because it means TVA can reduce debt and keep electric rates low.

So why would TVA announce that it doesn’t need new power for the next 15 years, sell a nuclear power plant capable of producing reliable baseload power for the next 60 years, and then turn right around and buy unreliable wind power that might only be available for 20 or 30 years assuming the turbines don’t break down?

TVA is on a good path. Its leadership has made sound decisions that will benefit ratepayers and our region. To fulfill its mission to provide “safe, clean, reliable and affordable power for the region’s homes and businesses” it has opened the first nuclear power reactor in the 21st century. It is placing pollution control equipment on all its coal plants, and it is completing new natural gas plants.

TVA has done this while reducing its debt and reducing electric rates, which is good news for jobs and economic development in the region.

Even if TVA did need more power – which it has said it does not – TVA should not agree to buy more wind power which is comparatively unreliable and expensive.

A look at TVA’s previous experience with wind power illustrates how unreliable wind power can be, especially in our region.

In 2001, TVA opened the first commercial-scale wind project in the Southeast. It is generous to say it has been a failure. This project on Buffalo Mountain near Knoxville has the capacity to generate 27 MW of electricity.

However, according to TVA, in 2016, the Buffalo Mountain wind turbines only provided 4.3 MW on average. This is just 16% of their rated capacity.

In other words, these turbines – which cost as much as $40 million to build and must cost millions over the life of its contract – produce little electricity and little value for TVA’s ratepayers.

Wind usually blows at night when consumers are asleep and don't need as much electricity.

And until there’s some way to store large amounts of wind power – a utility still needs to operate nuclear, gas or coal plants when the wind doesn’t blow.

Take for example a recent TVA peak summer day. On July 26, 2016, the Tennessee Valley homes and businesses consumed 29,512 MW of electricity – nearly all of TVA’s capacity of 33,000 MW of electricity.

Part of TVA’s capacity on that day included contracts for nearly 1,250 MW of electricity produced by wind power.

However, at the peak demand during the day, when power was most urgently needed, those wind turbines with a rated capacity of 1,250 MW actually delivered only 185 MW of electricity.

So on a day when the Tennessee Valley needed power the most, wind turbines provided less than 15% of their rated capacity and less than 1% of the total electricity needed to power our region’s homes and businesses.

Not only is wind power unreliable, it can be more expensive than nuclear – which also produces zero emissions – or natural gas – which is low emission.

TVA is currently completing a new 900 MW natural gas plant for roughly $975 million that will improve air quality in Memphis and be one of the most efficient natural gas plants in the world.

Natural gas plants usually operate for at least 30 years, and according to TVA can provide power in as little as 20 minutes to meet peak demand during hot summer afternoons and cold winter nights.

Last year, TVA opened the country’s first nuclear power reactor in the 21st century, Watts Bar II, at the cost of approximately $5 billion.

Watts Bar II will safely provide 1150 MW of power more than 90 percent of the time for the next 40, 60 and possibly even 80 years.

The point is: TVA has concluded that it doesn’t need more power for the foreseeable future. Therefore, its board should resist obligating TVA’s ratepayers for ANY new large power contracts, much less contracts for comparatively expensive and unreliable wind power.

Instead, TVA should continue to provide low-cost, reliable power to the region that boosts economic development throughout the Tennessee Valley.
