Wind Turbine to Be Constructed
Other Energy Projects Underway
Prior Lake, Minnesota - In the summer of 2008 the Shakopee Mdewakanton Sioux Community
will begin installation of a 2-megawatt wind turbine next to its Pow Wow Grounds. Several
years ago the SMSC installed a wind anemometer to determine if a wind turbine would yield
satisfactory results. Results were encouraging so the project moved forward. The center hub will
stand 262.4 feet tall and be visible for miles around. The three blades will be 229.6 feet in length
and will function like a propeller.
The wind turbine has little environmental impact. It is not located near a major bird or bat
migratory flyway. This single turbine will supply enough energy for a significant percentage of
the Community residential energy demand. Energy created by the turbine will be metered as it
enters a nearby electrical substation that provides electricity to the SMSC and the surrounding
area. The generated energy will likely be offset against Community residential energy costs.
Like many, the Community is faced with growing energy demands and dependence on
outside sources for that energy. Environmental impacts associated with conventional energy
sources are known to be destructive to the earth. In response, the Community has actively been
exploring local options to supply its energy demands. This focus will reduce some of the
environmental impacts associated with conventional energy sources like natural gas and oil.
Most of the solutions being pursued by the Community do not require extensive infrastructure.
Since initial investment costs are recouped over the life of the project, especially with rising
conventional energy costs, other options are preferred by the Community.
Minnesota is the third largest producer of wind energy in the nation, behind Texas and
California. The state of Minnesota has set renewable energy standard that requires 25 percent of
the state’s energy to come from renewable sources by 2025. The SMSC wind turbine is another
example to meet that goal.
The wind turbine is one of several Shakopee Mdewakanton Sioux Community energy
initiatives already underway. The SMSC is a major partner in Koda Energy, a joint venture with
Rahr Malting of Shakopee to produce heat and electricity by burning agricultural by-products
and grown energy crops. This stable, clean energy production facility will be operational by
December 2008 and could supply up to 75% of the Community’s energy needs for housing.
Another innovative project will soon convert the Community’s waste motor oil and vegetable
oil to heat buildings. Currently waste oil is hauled away; but by fall 2008, some Community
spaces will be partially heated by waste oil. Using waste oil for heat reduces the use of natural
gas. A project to convert 28,000 gallons of waste vegetable oil each year into bio-diesel for use
in Community vehicles and equipment is also underway.
The Community Fire Station addition scheduled for completion in June 2008 has
incorporated efforts to utilize the free energy of the sun. Four skylights with daylight harvesting
sensors will light a training room and equipment bay, reducing daytime energy usage. Six solar
cells on the roof will capture energy to heat water for showers and equipment washing, reducing
the use of natural gas. The new Ice Arena currently under construction will also feature skylights
specifically designed to compliment the arena use. Between the hours of 8:00 a.m. and 5:00 p.m.
weekdays, the arena typically will not have a lot of use. By using skylights and daylight
harvestings during these non-peak hours, energy consumption for lighting will be reduced by
about 50%.
Another energy saving feature of the Community’s new Ice Arena will capture waste heat
from the refrigeration compressors used to cool the rink floor and use it to heat the arena seats.
Dispersing heat in spectator spaces reduces the need to heat the entire arena. This reduces energy
consumption and makes the arena more comfortable for guests.
