You pay the kWh retail volumetric rate (including riders) for all MidAmerican power delivered to your home during each 15-minute period of the billing period (inflow). MidAmerican credits you the kWh retail volumetric rate (including riders) for all net power delivered to the grid during each 15-minute period of the billing period (outflow). The energy outflow is credited at the kWh retail volumetric rate and will carry over to a future billing period, if you contribute more energy to the grid than you used. These excess credits expire based on the annual billing year (January or April) you select.

 

To choose when you'd like your annual billing year to reset, complete the Rate IO election form.

 

With net metering, energy delivered to MidAmerican at the metering location is subtracted from the energy consumed (kWh consumed minus kWh delivered). If a customer consumes more energy than they deliver, the resulting net kilowatt-hour is billed to the customer at the same electric rate at which the customer normally purchases their energy from MidAmerican. If the customer delivers excess energy to MidAmerican's electric distribution system during the billing period, net metering provides the customer energy and/or delivery credits that can be stored in the customer's account for future use in subsequent billing periods. These excess credits expire based on the annual period (April or October) the customer selects in the Net Metering Application.

 

Note: Electric customers installing a distributed generation facility and seeking net metering in Illinois must provide an Installer Certification Form, a Net Metering Application and a copy of the installation invoice.
