    Customer generation – or distributed generation – systems are small-scale, on-site power sources located at customers’ homes or businesses. For questions related to distributed generation, please email privategeneration@midamerican.com.

    Iowa Applications and Rate Information

     
    Iowa residential customers are under the Inflow/Outflow Rate, while customers using small power production are under Rate QF.
     
    Inflow/Outflow Rate 
    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 this Rate IO election form.
     
    Home Solar Inflow/Outflow Rate and the process
     
    number one
    Solar panels take in sunlight and convert it to energy. Excess energy is put on the grid (outlow).
     
    number two
    If energy generated at location is not sufficient, energy is consumed from the grid/MidAmerican (inflow).
     
    number three
    Outflow (energy put on the grid) and inflow (energy consumed from MidAmerican) are recorded separately.
     
    number four
    Both inflow and outflow are then billed and credited accordingly on a real-time basis (15-minute increments).
     
    number five
    Outflow is credited and will carry over to a future billing period (if you contribute more energy than you use).
     
     
    Cogeneration and Small Power Production – Rate QF  
    MidAmerican offers a cogeneration and small power production rate for energy produced onto our electric distribution system from a FERC-approved qualifying facility.
     
    As a customer, you and your installers are responsible for following the interconnection rules of the Iowa Utilities Board, as well as meeting all MidAmerican requirements and those of your local city and/or county, as applicable. 
     
    Learn more about distributed generation in Iowa from the Iowa Utilities Board and the Iowa Energy Office.
     

    Illinois Applications and Rate Information

     
    Illinois customers are under Net Metering, while customers using small power production are under Rate QF.
     
    Net Metering – Rate NM
    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.
     
    Home Solar Net-billing
     
    number one
    Solar panels take in sunlight and convert it to energy.
     
    number two
    Energy is produced for the customer to use.
     
    number three
    Energy delivered to MidAmerican at the metering location is subtracted from the energy consumed and is evaluated on a monthly basis.
     
    number four
    Excess energy produced by the customer is credited in the customer’s account via delivery credits, or the customer will be billed for over-consumption.
     
     
    Cogeneration and Small Power Production – Rate QF
