Energy Independent Communities Pilot Project: Chequamegon Bay Region
This project was made possible by grant funds from the Wisconsin Office of Energy Independence.
The Problem
In 2007, Wisconsin spent $21.5 billion dollars on energy Nearly ALL of which was spent out of state to import coal
and petroleum products. A 9.9% increase ($1.9 billion) over 2006. 25% shift to local renewable energy sources is equal to $5.4 billion that stays in the State of Wisconsin Fossil fuels:
Have many negative impacts on people
and the environment. Are costly and FINITE resources. Are not derived locally.
Estimated Clean Energy Job Creation in Wisconsin
Wisconsin is #1 in manufacturing – many “green” jobs will
be developed in these industries
A clean energy economy will need:
Metal Workers – wind turbine components, biofuel processing equipment Weatherization and Building Professionals – energy efficiency retrofits and
renewable energy component installation Engineers, Research & Development Specialists, Community Planners
Compared to fossil fuels, clean energy investment could
produce:
3 times more jobs for people with college degrees 3.6 times more jobs for people without college degrees *Information provided by the Local Government Institute of Wisconsin
The 25 x 25 Challenge Executive Order 192
The Office of Energy Independence Energy Independent Communities
The Goals of the 25 x 25 Plan:
Derive 25% of our energy &
transportation fuels from renewable sources by the year 2025. Attract 10% of the emerging US bio-industry jobs to Wisconsin.

Regional Wind Energy Consortium Purposes:
Promote regional collaboration; build knowledge and skills. Develop a common voice around wind energy in region.
Larry Bean/Mark Abeles-Allison, Chair/Vice Chair. Alliance provides central coordination. Inaugural meeting held July 14. Open to others interested in pursuing local wind energy.
Bayfield County Wind Energy Efforts Background
Looking for ways to cut costs
& save taxpayer dollars
Wind generation in Bayfield
County Forest could meet most local electricity demands, save money, and decrease greenhouse gas emissions.
Turbines would sell power to
grid, offsetting Bayfield County’s electricity costs
Bayfield County Wind Energy Efforts Benefits
Approximately 10 year payback, with remaining
years in operation generating ongoing profits. Anticipated lifespan of the turbine is 25-30 years.
Progress
Located potential sites on county forest land. Site Assessment completed August 27, 2008. Mt. Ashwabay ridge has the most wind potential
and close proximity to existing power lines. Partnered with the Dept. of Natural Resources, Les Voigt Fish Hatchery on wind study. Applied for and received Focus on Energy grant to help pay for wind study. Received grant from Apostle Islands Area Community Fund, Bayfield County and DNR.
Wind study progress
30 Meter Meteorological tower erected early June 2009, duration
of study is approx. 1 year
Wind speed average from June thru November: 30 meter 9.2 mph,
20 meter 7.1 mph Summer and early fall is the least windy part of the year, so wind averages will likely increase through the winter Wind shear is quite high - wind speed dramatically increases with height which is good because a potential turbine hub would be 7580 meters high.
SODAR (Sonic Detection and Ranging) deployed early October
2008, SODAR completed late November 2008.
SODAR measures wind speed and wind shear up to 150 meters
through acoustic frequencies No analysis from SODAR unit at this point
Wind study progress • DNR and County swap out data cards once a month from MET tower and send data to Superior Safety and Environment for analysis. • County has cleared a second site further west of current site to measure wind speed at that location with SODAR next spring. • Wind speed may be better and site is even closer to power lines. • Second site will be even further away from private residences, gain more wind and allow us to get a better handle on the wind potential on the Mt. Ashwabay ridge.
Next Steps
Analyze data from Met tower and SODAR.
Determine if wind power is a feasible option for the County and DNR. Possible collaboration with Madeline Island on locating their turbines on the Mt. Ashwabay ridge.

Assembling the Met Tower at Big Bay State Park Oct. 27, 2008
Pulling up the gin pole will erect the Met Tower.
Madeline Island wind energy efforts in 2009 have focused on…
1) analyzing the wind data from the Big Bay State Park measurement program. 2) estimating the projected year 2025 total Madeline Island electrical load.
3) calculating the number, the size and the height of the turbines necessary to supply 100% of the year 2025 load. 4) determining the most feasible location for these turbines. 5) estimating the cost of the wind energy project and the length of the break-even period.
What has the measurement program told us? Average Wind Speed = 11.1 MPH @ 161 feet elevation (Nov. 1, 2008- Oct. 31, 2009) Max Speed averaged over a single month = 13.9 MPH (Dec. 2008) Max Speed averaged over a single day = 25.3 MPH (May 13, 2009)
Max Speed averaged over a 10 min interval = 43.0 MPH (5/20/2009) Max Gust w/i 10 min interval = 51.7 MPH (1/31/09)
# of 10 minute measurement intervals w/valid data = 47,910.

22.4 MPH
33.6 MPH 41
What has the measurement program told us? The data reveals considerable wind turbulence at BBSP up as high as 164 feet.
SODAR Equipment
This is not a surprise because Madeline Island is heavily forested. A corn field would be better. We conducted a new measurement program using different equipment (SODAR) to get a better handle on turbulence up to a height of about 450 feet. This SODAR program was funded by a grant from Xcel Energy and lasted approx. one month.
Providing 100% of Madeline Island’s 2025 load is our goal. We need to plan for six to seven 600kW turbines (or equivalent). They will need to be installed on 246 ft high towers. The project would be sized at approximately 4 Megawatts and is estimated to cost about $12 million. Break even will be about 12 years (first order analysis).

• During that time, we will have to answer the following questions: • What are the environmental impacts? • How would this program be financed? • What would be the ownership model? • What are the benefits for the Town and community members? • Who would be the developer? • Who would manage and maintain it? • When could it be installed and put on line? •We will apply for additional grants to fund this effort.
