Expected to output around 30% of its rated capacity per year since wind does not blow all the time in this area.
Became operational in October 2009.
From October 2009 through March 11, 2010, the turbine generated 800,000 kWhrs (kilowatt hours).
It has run for about 2,200 hours of the available 3,000 hours or about 73% of the time.
The turbine blades turn from winds as slow as six and a half mph and continue through about 40 miles per hour (mph) when it shuts itself off.
Payback period is at least 15 years.
The $1.8 million wind turbine has a life expectancy of 30 years.
Minnesota is the third largest producer of wind energy in the nation, behind Texas and California.
An anemometer was installed on SMSC land in 2001 to collect wind data.
The data collected since 2001 shows a range from 0 to over 25 mph wind with an average speed of 11 mph at an elevation of 164 feet.
Federal aviation requirements due to the nearby Flying Cloud Airport in Eden Prairie, Minnesota, mandated the maximum height at the tip of the blade at 1,340 feet above sea level.
Energy created by the turbine is metered as it enters the nearby Minnesota Valley Electric Cooperative (MVEC) substation where it is certified as a renewable energy source and sold by Basin Energy on the open market.
The value of the generated energy is offset against SMSC energy costs.
MVEC installed two transformers and a meter/controller to get the power matched to the substation needs.
About twice a year maintenance is required.
Ground site preparation was completed when the foundation ring was installed and buried 12 feet underground in August 2009. It was later covered with sod.
The foundation ring is 14.76 feet by 9.84 feet, with a weight of 14.3 tons.
The center hub stands 262.4 feet tall and is visible for miles around.
The hub is 13.45 feet by 13.45 feet by 11.48 feet and weighs 17.19 tons.
The turbine nacelle (generator housing) weighs 57.3 tons without the blades.
The nacelle is 31.18 feet by 12.46 feet by 13.12 feet.
The three blades are 123 feet each in length by 7.35 feet by 9.84 feet and weigh 6.6 tons each.
When assembled in the hub, the diameter of the circle created by the blades is about 77 meters, or 247 feet.
The 252.3 feet tall steel tower is tubular shaped and weighs 135.9 tons.
Maximum height at the tip of the blade is 1,340 feet above sea level.
At 386 feet from foundation to the tip of a blade fully extended vertically, the wind turbine has the equivalent height of a 38-story building.
Changzhou Railcar Propulsion Engineering Research and Development Center of Changzou, China, built the SMSC wind turbine.
Vendor selected due to ability to provide wind turbine at best price and quickest delivery time.
Components were shipped over a seven week voyage first to Shanghai and then to Houston, Texas, where it was loaded onto trucks for its overland journey.
About 72 hours were needed for the pieces to be transported from Houston to Minnesota.
From port the wind turbine components traveled about 1,200 miles on nine different trucks.
A team of four engineers traveled to Minnesota from China for the assembly, testing, and commissioning of the wind turbine.
Once all the parts arrived, it took about two days to assemble using a 600 ton capacity crane with 335 feet of boom.
It took about 50 hours to assemble the wind turbine start to finish.
About 400 man hours were needed.
Diversified Energy Solutions of Gary, South Dakota, installed the wind turbine.
October 3-4, 2009, the SMSC wind turbine was assembled under cold and rainy skies.
Commissioning of the wind turbine took several weeks.
The SMSC turbine has an Arctic Kit with internal heaters, gearbox heaters, and insulation for all parts to survive the harsh Minnesota winters.
Several hundred of this model (FD-77-1500 60 IIIA) are running in Mongolia, which has a Siberia-like climate.
The SMSC wind turbine is believed to be the tallest wind turbine in the metropolitan area.
