* Facilities Charge & Energy Adjustment Clause applies.
** Demand Charge applies.

Facilities Charge
This charge covers fixed costs that Musctine Power and Water incurs to service each customer, regardless of usage. These costs include service facilities, meter reading, bill distribution, and payment processing.

Energy Adjustment Clause (EAC)
This adjustment reflects the variances in purchased power costs and wholesale energy margins (wholesale energy revenue less delivered fuel cost) from the costs/margins included for these amounts in our electric base rates. For more detailed calculations, please refer to the Electric Rate Brochure.

Demand Charge
This charge applies to some commercial and all industrial customers and is measured in kilowatts (kw). This is a measurement of capacity or the rate at which energy is used.  Demand represents the amount of energy used in 30-minute intervals during a billing cycle.  To measure demand, electric meters record the average demand usage over each 30-minute period and record the highest (peak) 30 minute period for the month.  Customers are billed on the peak value.

Business customers: to find out if you are a Commercial I or II, or an Industrial I or II customer, please contact the Energy Services Department at (563) 262-3354.
