Power From Wind
PPI has added wind
power to TVAs renewable energy sources with the dedication of a
new wind-turbine park near Oak Ridge, Tennessee. The Buffalo Mountain
Wind Park represents the first commercial use of wind power to generate
electricity in the southeastern United States.
huge wind-powered generators were erected on the two-acre site in the
fall of 2000 at a cost of $3.4 million. The generators add about two megawatts
of capacity to the TVA power system and produce some six million kilowatt-hours
of electricity a year, enough to serve more than 400 typical households
in the Tennessee Valley. Electricity from the turbines is fed into the
nearby Clinton Utilities Board power system, which is connected to the
TVA power grid.
electricity is sold through TVAs clean-energy option, called Green
Power Switch. The program gives consumers the option of adding electricity
generated by renewable sources to the existing power mix.
site on Buffalo Mountain was chosen for several reasons:
- Existing 161-kilovolt
and 69-kilovolt TVA power distribution lines cross the site.
- Clinton Utilities
Board has distribution lines on two sides of the mountain, and the Tennessee
Communication Company has a three-phase line within one mile of the
data is available from both TVA and the National Oceanic and Atmospheric
- The site is an
abandoned strip mine. Such sites in the Tennessee Valleyflattened,
treeless areas at elevations above 3,300 feetcould be ideal locations
for wind parks.
- The environmental
community enthusiastically supports the recycling of abandoned
strip mines into a new source of renewable energy.
PPI is working with
AWS Scientific and True Wind to evaluate other potential wind park sites.
TVA estimates the current two-megawatt capacity could be expanded to 25
or 50 megawatts.
