About the Pretty Prairie project:


– The proposed Pretty Prairie Wind Farm is expected to consist of more than 80 wind turbines; the developer, NextEra Energy, asked the Federal Aviation Administration to evaluate 91 turbine sites to ensure they are not a hazard to aircraft.

– NextEra has said the turbines will be capable of generating 220 MW when operating at maximum capacity. One megawatt – or 1 million watts – if generated continuously can power 840 homes. Historically, Kansas wind farms generate about 40 percent of their rated capacity (because the wind doesn’t blow continuously). Based on that, the wind farm would produce enough to electricity to power 75,000 households.

– Last year, a Boston-based company, Iron Mountain, announced that it signed a 15-year power purchase agreement with NextEra to take 145 MW of electricity from the Pretty Prairie Wind Farm. A spokesman for NextEra said it has also signed a power agreement with Home Depot for 15 MW.

– The current cost of fuel required to generate the wind farm’s annual power output is about $700,000.

– In Kansas, wind farms are exempt from property taxes for 10 years. Based on industry estimates of wind farm construction costs (NextEra declined to say how much it will spend building the wind farm), NextEra will save approximately $56 million in property taxes during that period.
