Net Billing Program

Western Illinois Electrical Coop. is pleased to offer a Net Billing program for our members, now that our Net Metering program is fully subscribed.

With Net Billing, members using a renewable energy system first utilize their generated power at their location, getting full retail value for those generated kilowatt-hours (kWh). Any time the renewable energy system is producing more energy than the location is using, the excess energy is sent to WIEC electric grid. At the end of the month, WIEC pays the member for that excess energy at our on-peak wholesale energy rate which is set annually by Prairie Power Inc.
