Service Charges

Upon applying for services, there is a $25.00 service fee for each service-power, natural gas, water, and wastewater. For instance, for a customer applying for power only, the total service charge will be $25.00. For a customer applying for power and natural gas, the total would be $50.00, and so on. This fee is not refundable.
