Residential Rates


Duquesne Light Company's rates for customers are determined by a filing made at the Pennsylvania Public Utility Commission. The entire filing is called a tariff. The tariff contains rules and regulations as well as the schedule of rates and riders for electric service as approved by the Pennsylvania Public Utility Commission.

A customer's bill is made up of four parts: Customer Charge, Distribution Charges, Supply/Generation Charges and Transmission Charges. Those definitions are on page two of your bill and are reproduced here:

Customer Charge - A monthly charge on your bill that includes our costs for meter reading, customer billing, service equipment, implementation of advanced metering and other expenses. We have these expenses even in months that you may not use electricity. The advanced metering technology and related infrastructure will provide, in the next several years, the ability for features such as two-way communication, hourly usage information and electric-price information.

Distribution Charges - Charges for the use of local wires and other equipment that deliver electricity to consumers and for energy efficiency programs that conserve energy and reduce demand.

Supply/Generation Charges - Charges for production of electricity.

Transmission Charges - Charges for moving high-voltage electricity from a supply facility to the distribution lines of an electric distribution company.

The schedule of rates or tariff is available for download (right click, select Save Target As) in Adobe Acrobat Reader PDF format. This tariff has been approved by the Pennsylvania Utility Commission and is currently in effect. The tariff contains detailed information about the different rates available to residential customers (Residential Service (RS), Residential Service Heating (RH) and Residential Service Add-on Heat Pump (RA)). Duquesne Light Company has certified to the Pennsylvania Public Utility Commission that this is an accurate electronic representation of the tariffs which are officially filed at the Commission. Users of electronic tariffs should note, however, that such tariffs are not the official documents, and users assume responsibility for reliance upon tariffs in electronic format.
