Rates, fees & cost adjustments

We are a not-for-profit municipal utility, and we serve our customers, not shareholders.

We believe in keeping rates as low as possible, and we also believe in transparency in how your bill is calculated each month.

When we talk about rates, there are two different aspects: base rates and cost adjustments.

Base rates

Base rates reflect the costs associated with producing and delivering each service to customers.

Base rates pay for the operation and maintenance of power plants, water collection and distribution systems, wastewater treatment, metering and billing systems, and more.

The physical things you see, such as poles, wires and pipes, are financed through base rates.

Cost adjustments

Cost adjustments only apply to electric and natural gas services. Prices for natural gas and electricity can change quickly and are uncontrollable.

We typically adjust rates each quarter to account for increases and decreases in these prices. Increases or decreases are passed directly to our customers. 

Natural gas cost adjustments directly reflect the cost to serve our customers with natural gas appliances. Since natural gas is a source of electric production, electric cost adjustments are also affected by fluctuations in natural gas costs.

City Council approved changes to electric and natural gas fuel rates and capacity charges on June 24.

The total bill impact for the average residential customer bill is $0.25. Individual customer bill impacts vary depending on weather, household use and home efficiency.  

The new rates are effective July 1.
