New Wind Energy Center

When customers of Cedarburg Light & Water flip on a light switch or plug in a device, they now receive more than twice as much of their electricity from wind power. The additional renewable energy is generated at the new Bishop Hill III Wind Energy Center. “Not only are we adding more renewable energy to our power supply portfolio with Bishop Hill III,” said Andy Moss, Cedarburg Light & Water Utility Commissioner, “we are doing so cost effectively.”

The utility’s wholesale power supplier, WPPI Energy, entered into a power purchase agreement with Invenergy last summer to buy electricity from the 132-megawatt facility located in Henry County, Illinois. Cedarburg Light & Water is a member-owner of WPPI Energy.

Construction on the Bishop Hill III Wind Energy Center began in August 2017, and the facility started service in May of this year. To officially mark the opening of the Bishop Hill III facility ribbon cutting ceremony was held in Woodhull, Illinois. Beyond renewable energy, this project also delivers environmental benefits. Not only does Bishop Hill III more than double the WPPI Energy membership’s use of wind energy, but when combined with the addition of solar power from Point Beach Solar Energy Center, which is expected to come online in 2021, the project will also help Cedarburg Light & Water achieve a power supply portfolio that is:

  • Made up of more than 22 percent renewable energy
  • Nearly 40 percent emissions-free, and
  • Approximately 40 percent lower in carbon dioxide emissions compared to levels in 2005. 

WPPI Energy will purchase the electricity from Bishop Hill III through mid-2040 in order to serve its 51 member utilities across Wisconsin, Michigan’s Upper Peninsula and Iowa, including Cedarburg Light & Water. The agreement represents WPPI Energy’s largest renewable energy purchase to date.
