Private Generation

Private generation – also referred to as distributed generation – systems are small-scale, on-site power sources located at or near customers’ homes or businesses.

About Private Generation

MidAmerican Energy considers private generation to be any electric power generation rated 10,000 kilowatts and below that interconnects to MidAmerican Energy’s electric distribution system at voltages of less than 100 kilovolts.

Customer-generated power can be made with renewable or nonrenewable fuel sources such as small wind turbines, rooftop solar units, internal combustion engines, gas turbines and fuel cells.

Before You Install Private Solar

MidAmerican Energy does not install or maintain customer-owned private generation systems. Prior to installing private solar panels, use this checklist to gain a better understanding of the installation process and to track important information.

Safety and Reliability

MidAmerican Energy provides energy to private generation customers when a customer's private generation source isn’t producing enough energy to meet their needs. Customers who install a private generation system must complete the private generation interconnection process, enter into an interconnection agreement, and receive written permission before operating a private generation system in parallel with MidAmerican Energy’s electric distribution system. The interconnection process protects other customers and employees from risks that could result from the improper installation of private generation.

Private Generation Rate Structure

A private generation customer can sell any excess energy they generate to MidAmerican Energy. If the customer has all the energy he or she needs, excess energy is sent through the customer's meter to the grid, and MidAmerican Energy credits the customer. This is called net metering.

Net metering does not involve separate purchase and sales transactions – it simply tracks the difference between usage and production, which would be the net amount. MidAmerican Energy’s private generation customers draw energy from and provide excess energy to MidAmerican Energy. This results in production netting against power supplied by MidAmerican Energy.

A customer can choose between two rates applicable to private generation, the Net Metering Rate and the Cogeneration and Small Power Production Facilities Rate. The net metering rate is not available to South Dakota customers.
