Fascinating Facts:

  • In 1998, Moorhead Public Service's first wind turbine was fully subscribed in less than three weeks. With a waiting list of about 100 customers, MPS offered its customers another chance to receive clean, wind energy during Capture The Wind® Week in October 2000. Within one month, over 400 more customers had joined in the crusade to "Capture The Wind" in Moorhead, and the utility had fully subscribed its second wind turbine.
  • Moorhead Public Service's first wind turbine was officially named "Zephyr" by our Capture The Wind® members on April 25, during Earth Week 2001. Moorhead Public Service's second wind turbine was officially named "Freedom" by our Capture The Wind® members on April 24, 2002, during Earth Week.
  • By October, 2004, our twin turbines have generated over 13 million kWh of clean, wind energy.
  • By substituting wind energy for coal-generated power, our Capture The Wind® members have effectively prevented the emission of 16 million pounds of greenhouse gases into the environment, which has the same effect on the environment as removing 1,645 cars from the road or planting 2,243 acres of trees.
  • In 1999, Moorhead Public Service received the Minnesota Environmental Initiative Award for its Capture The Wind® program.
  • Over 900 MPS customers (7%) participate in the Capture The Wind® program. With the addition of over 400 new Capture The Wind® members in 2000, the National Renewable Energy Laboratory (NREL) now ranks Moorhead Public Service first in the nation for its customer participation rates.
  • Moorhead Public Service received the American Public Power Association's Energy Innovator Award in 2001 for its successes with the Capture The Wind® program.
