This charge is the wholesale power cost which covers the cost of generating and transmitting power from the power plant to MJM substations. MJM does not generate its own electricity. Instead, we purchase it wholesale from a generation and transmission cooperative in Indianapolis. Like other electric companies, MJM bases its power supplier energy charge on kilowatt hours (kWh). One kilowatt hour is equal to 1,000 watt hours. A watt hour is the amount of energy used by a one-watt load drawing power for one hour. For example, a 100-watt light bulb uses 100 watts of power in one hour.

If your home uses electricity as its primary heating source, you may be eligible for a discount on your rate during the winter months of November, December, January, February, and March.

This charge is for the maximum amount of electrical energy consumed at any given time, measured in kilowatts (kW).

This charge recovers a portion of the cost to get the power from the substation to the meter and is based on kilowatt hours.

This charge covers the cost of maintaining the equipment used to send electricity to your home. This includes the cost of transformers, meters, lines, and poles. Your service delivery charge remains the same each month and is based on your power needs.

The remaining charges on your bill are taxes and any additional services you may have with MJM, such as a security light. Illinois Public Utility Tax is .0032 cents per kilowatt hour.
