Wind Powering America Case Study: Port of Milwaukee Wind Turbine

May 6, 2013

The City of Milwaukee's Office of Environmental Sustainability and the Port of Milwaukee partnered to install a Northern Power 100-kilowatt (kW) wind turbine at the Port administration building near the shore of Lake Michigan. Commissioned in February 2012, the wind turbine provides more than 100% of the electricity needs of the administration building with its excess energy sold to We Energies.

In its first 9 months of operation, the project resulted in more than $5,000 in net revenue for the port after all electric expenses were paid. The estimated annual savings to the city are $14,000 to $20,000 (at 2011 rates, revenue included). Estimated annual production is 109,000 to 152,000 kilowatt-hours.

The turbine was manufactured in the United States, and many parts, including the tower, were made in Wisconsin. The $587,000 project received the bulk of its funding from the American Recovery and Reinvestment Act ($400,000) and $100,000 each from We Energies and the statewide Focus on Energy program.
