Reliable electric service results from three essential processes:
  • Generation – producing or supplying electricity;
  • Transmission – bringing high-voltage electricity from the point of generation to substations and transformers that provide electricity to residential neighborhoods; and
  • Distribution – bringing reduced-voltage electricity to individual homes and businesses.
MidAmerican Energy provides all three essential processes as a bundled service.

The Illinois Electric Service Customer Choice and Rate Relief Law of 1997 restructured the state's electric service industry. As a result, customers have choices about who supplies their electric power. Electricity is available from alternative retail electric suppliers certified by the Illinois Commerce Commission and registered with MidAmerican Energy.
