Customer Generation

Customer generation – or private generation – systems are small-scale, on-site power sources located at or near customers’ homes or businesses.

About Private Generation

Private Generation projects are electric power generators either directly interconnected to MidAmerican Energy's electric distribution system or connected to the electric facilities of a MidAmerican Energy electric retail customer. An interconnection is the connection of electric facilities between MidAmerican Energy and a customer. Private generation includes only electric generators that ultimately interconnect to MidAmerican Energy's electric distribution system at voltages less than 100 kilovolts.

Common Technologies

Common private generation technologies include but are not limited to wind turbines, solar, internal combustion engines, gas turbines and fuel cells.

Net metering is a billing method offered to eligible renewable private generation facilities located in MidAmerican Energy's Iowa and Illinois service territories. An eligible facility is rated up to 1,000 kilowatts (up to 100% of customer's load) in the company's Iowa service territory or up to 2,000 kilowatts in the Illinois service territory, which is powered by alternate energy sources such as solar, wind, dedicated crops grown for electricity generation, anaerobic digestion of livestock or food processing waste, or hydroelectric energy.

With net metering, energy delivered to MidAmerican Energy at the metering location is subtracted from the energy consumed (kilowatt-hour consumed minus kilowatt-hour delivered). If a customer consumes more energy than it delivers, the resulting net kilowatt-hour is billed to the customer at the same electric rate at which the customer normally purchases its energy from MidAmerican Energy. If the customer delivers excess energy to MidAmerican Energy's electric distribution system during the billing period, net metering provides the customer energy credits that can be stored in the customer's account for future use in subsequent billing periods.

Customers interested in net metering must complete and submit a net metering application (Illinois only), and must then complete the interconnection process as described on the private generation page. The net metering application (Illinois only), and applicable net metering tariffs and frequently asked questions for each state are:
