Business Rates

We make sure you understand your energy rates and choices.

Distribution Charges

All business customers – regardless of whether you receive your electric supply from Duquesne Light Company (“DLC”) or from an Electric Generation Supplier (“EGS”) – are responsible for paying Distribution Charges to DLC. Distribution Charges can consist of a Customer Charge, an Energy Charge and a Demand Charge, depending on which Rate Schedule you take service under.

Supply and Transmission Charges: Default Service

Duquesne Light’s Rider No. 8 - Default Service Supply ("DSS") provides small and medium commercial and industrial customers with default service supply rates that are determined based on Request for Proposals (“RFPs”). For purposes of Rider No. 8, small customers are those customers with a monthly metered demand that is less than 25 kW and medium customers are those customers with a monthly metered demand that is 25 kW and less than 200 kW, on average, in a 12-month period. Additionally, if you select DLC to supply your electricity, the Company will provide and charge for transmission service. The Transmission Service Charges (“TSC”) can be found in Appendix A of the Retail Tariff.

To learn more about DLC's Rider No. 8 or Appendix A, please visit the Company’s Retail Tariff.

Customers who elect to purchase their electric supply from an EGS must purchase both their electric supply and transmission service from their selected EGS and are responsible for any other charges from the EGS. Any month in which your supplier becomes unavailable or during which the customer has not chosen a supplier, DLC will supply electricity as per the provisions of Rider No. 8 – Default Service Supply and Appendix A – Transmission Service Charges.

Customers can switch to an Electric Generation Supplier (“EGS”) at any time. At the bottom of this page you can find price to compare information, which is helpful when comparing offers from EGSs. To see a list of licensed EGSs in Pennsylvania, please visit PAPowerSwitch.com.

SUPPLY AND TRANSMISSION CHARGES: HOURLY PRICE SERVICE

Duquesne Light’s Rider No. 9 – Day-Ahead Hourly Price Service (“HPS”) provides medium (≥ 200 kW) and large commercial and industrial customers with the ability to purchase their electric supply requirements on a day-ahead, hourly basis. Electric supply charges for Rider No. 9 customers are more closely tied to hourly wholesale market prices. Duquesne Light does not set these wholesale market prices. This means that HPS customers’ electric supply charges could experience more fluctuations, which could increase or decrease the amount of their bills. HPS customers are placed on a monthly billing cycle and are not eligible for summary billing. Rider No. 9 is also available for the supply of electricity to generating stations that are not otherwise self-supplying and where the generating station is not otherwise receiving service from an EGS. If you select DLC to supply your electricity, the Company will provide and charge for transmission service. The Transmission Service Charges (“TSC”) can be found in Appendix A of the Retail Tariff.
