NEW WIND FARM IN TEXAS TO BE HOME OF
LARGEST WIND TURBINES IN NORTH AMERICA
Customers of Texas Utility Ask for Wind Power and Get It

A wind farm that will feature the largest wind turbines ever erected in North America will be unveiled Wednesday, December 3, at the dedication ceremony of the Big Spring Wind Power Project in Big Spring, Tex.  State utility Texas Utilities Electric (TU) of Dallas, Tex. and York Research Corporation of New York, N.Y., will start up generation in the first phase of the $40 million project that will soon provide 117 million kilowatt-hours of green power annually.

Four Vestas V-47 wind turbines will be activated during the ceremony to begin providing power for TU, the local electric utility buying the power. In February 1999, when the entire wind farm is completed, it will have the capacity to power 7,300 homes, and it will feature 46 wind turbines reaching as high its 370 feet, with rotors more than 216 feet in diameter (see graphic below). York Research is responsible for the development, construction and management of the new wind farm.

Spurred by overwhelming support from TU customers for renewable energy, the utility decided to commit to purchasing all of the electricity generated at Big Spring Wind Power facility for the next 15 years. When asked in a survey conducted last October whether their local utility should invest in renewables, 96% of TU customers said yes. By a 10 to 1 margin, those same customers said they would be willing to pay at least one dollar more per month for energy from renewable energy sources such as wind power.

"Texans have overwhelmingly told their electric companies that they want more renewable energy because they want clean air," said Patrick Wood III, Chairman of the Public Utility Commission of Texas.

"We are thrilled by the fact that customers have requested clean, low-cost green power, and are getting it," said Randall Swisher, executive director of the American Wind Energy Association. "We are also equally excited that the largest turbines in the U.S. and North America are part of a surge in wind power's growth across the U.S. over the next seven months. During that time, our country will increase its wind power capacity by 50%, and Big Spring is the first in that new wave of wind farm development."

This illustrates the size of the turbines at the Big Spring Windpower Project.

  • Total capacity is approximately 34,000 kilowatts (34 megawatts).
  • Total energy output is estimated to be 117 million kWh per year, enough to serve 7,300 homes annually.
  • Wind power costs from this project will average 5.2 cents per kWh over the 15-year term of the purchase agreement, In comparison, new natural gas generation costs from 2.7 to 5.2 cents per kWh.
  • The Wind Power Project is located at a site about eight miles east of Big Spring -- population 24,000 -- that has an average annual wind speed of 18 mph.
  • Turbines are manufactured by Vestas Wind Systems of Denmark.

WIND POWERS AMERICA is a special series of news releases that highlights new wind projects as the U.S. wind industry undergoes a major expansion between now and July 1999. As new wind farms are completed, WIND POWERS AMERICA will encapsulate information from each project, including the local or regional environmental and economic impact.
