Massive Wind Power Opportunities for Tennessee

Buffalo Mountain Wind Farm, Tennessee

This post is the second in a blog series discussing state-by-state highlights of wind energy throughout the South in the lead up to the WINDPOWER Expo in Orlando, FL, May 18 – 21. See the rest of the series here.

New wind turbine technology is a game changer for clean energy opportunities in Tennessee. Taller turbines and longer blades are capable of capturing more wind, which results in generating more electricity and reducing costs. In just five years, wind turbines have greatly evolved and are now more suitable for the Southeast. One modern wind turbine can now power the equivalent of about 600 homes a year!

New wind speed maps released by the National Renewable Energy Laboratory (NREL) demonstrate the greatly increased potential for wind turbine development in Tennessee with advanced turbines. As wind turbines increase in height and are able to access better wind speeds, more areas become attractive for wind energy development within Tennessee.  The shading on the map below represents new available land for wind development with modern turbines with towers of 360 feet (110 meters) achieving a 35% capacity factor or greater. With these new wind turbines, over 60,000 megawatts (MW) of land-based wind potential currently exist in Tennessee. Developing just one gigawatt of wind energy capacity (1,000 MW) in Tennessee (just 1.7% of Tennessee’s potential) could power more than 255,500 homes a year!

Based on the Jobs and Economic Development Index model, developed by NREL, developing one gigawatt worth of wind energy capacity in Tennessee could support approximately 4,800 direct, indirect and induced jobs during construction and over 160 ongoing operation jobs with a total annual payroll of $9 million.

Tennessee is home to the Southeast’s first wind farm, the Buffalo Mountain wind project. This wind farm was installed nearly a decade ago and is still meeting performance goals and expectations. Several other wind farms have been proposed in Tennessee. Meanwhile, the Tennessee Valley Authority is currently purchasing over 1,500 megawatts of wind power from the upper-Plains states. Proposed High Voltage Direct Current (HVDC) transmission projects, like the Plains and Eastern project, would inject thousands more megawatts of new high quality, low cost wind power for the Volunteer State.

Tennessee is also home to at least 10 wind energy-related manufacturing facilities serving the domestic and international wind industry markets. In 2013, there were up to 100 direct and indirect jobs provided by the wind industry in Tennessee. Developing land-based wind in the state could greatly add to local economic benefits and create more wind energy-related jobs. A few of the wind energy-related companies in Tennessee include:

  • Barnhart Renewables (Knoxville, TN) Services range from turbine erection to on-going maintenance and repair. Barnhart has installed over 3,000 megawatts of power in the wind industry for manufacturers, developers, and owners, including Tennessee’s Buffalo Mountain wind farm.
  • EnerNex (Knoxville, TN) an electric power engineering and consulting firm specializing in the development and application of new electric power technologies.
  • Flash Tech (Franklin, TN)  provides specialized obstruction lighting products to serve the telecommunications, broadcast, wind energy, airport, utilities markets and specialty applications to comply with Federal Aviation Administration lighting regulations.
  • International Tower Lighting, LLC (Nashville, TN) designs and manufactures obstruction lighting systems and components for towers.

The Southeastern Wind Coalition has published wind energy fact sheets on this state and others from around the Southeast. You can access those fact sheets here.

As the Southeast becomes a new frontier for wind energy, it is only fitting that the largest wind energy conference of the year will be in Orlando, Florida. Join us, May 18-21, 2015 for the American Wind Energy Association’s (AWEA) annual WINDPOWER Conference & Exhibition in Orlando. Each year, the event draws thousands of attendees and hundreds of exhibitors all looking to advance the wind industry. WINDPOWER features over 30 sessions ranging from market and policy analysis, to project performance and technical advancements in wind energy. It’s an excellent way to connect with subject matter experts–anyone interested in the wind industry should plan on attending. As a benefit to you for reading our blog, you can use this discount code to receive $50 off the full registration: SPKWP50.

We hope you can join us in Orlando to learn more about wind energy opportunities for Tennessee and the entire Southeast! You can register here.
