Renewable Resources Diversify Power Supply

   Increasing the amount of renewable energy in WPPI's power supply portfolio is a key strategy in helping to stabilize future power costs. Renewable resources are also sustainable and cleaner than traditional sources such as fossil fuels, which release carbon dioxide when burned and contribute to climate change.

   Renewable resources projects currently in development include the following:

Top of Iowa II. A 20-year purchased power agreement with a subsidiary of Iberdrola Renewable Energies USA will add 50 MW of renewable energy generated at a wind facility near Kensett, Iowa. The facility is expected to supply WPPI with enough electricity to power the annual needs of approximately 16,000 homes beginning in December 2007.

Outagamie County Landfill. WPPI will purchase 4.8 MW of electric power generated from methane gas produced at a landfill in Outagamie County, Wis. The power will be delivered to the electric distribution system of Kaukauna Utilities, a member of WPPI. The project's three generators came online in early 2007.

Butler Ridge. In 2006, WPPI began negotiations to purchase the entire output of a wind project to be constructed in the town of Herman in Dodge County, Wis. Known as Butler Ridge, this 54 MW project will supply enough capacity to power 15,000 homes. The project is scheduled to be in service in 2008.

Forward Energy Center. WPPI expects to purchase 25 MW of renewable energy — enough to power the annual needs of more than 6,500 homes — from the Forward Energy Center wind project near Brownsville, Wis., just east of WPPI member community Waupun. While the project has faced delays due to permitting concerns, WPPI is optimistic that the project will move forward.

   WPPI's renewable energy portfolio includes allocations of renewable energy through purchases from other utilities and the output from a refurbished, 7 MW, low-impact hydroelectric plant near Black River Falls, Wis. WPPI also owns two wind turbines near Worthington, Minn., with a combined generating capacity of 1.8 MW.
