Duquesne Light, the electric utility serving Pittsburgh, Pennsylvania and surrounding areas, is forecasting significant increases in its electric rates for customers who do not shop for an alternative electric supplier.

For customers who do not choose their own electric supplier, Duquesne Light provides backstop power supply known as "default service."  For this default power supply, Duquesne Light charges a "Price to Compare", or a rate for the customer's generation supply.  Customers who buy their power from a competing electric supplier avoid, or bypass, the Price to Compare, and instead pay a competitive electric rate negotiated with their supplier.

For most residential and business customers, the Duquesne Light Price to Compare changes every 6 months. It will next change on June 1.

Although an official Price to Compare has still not been issued yet, Duquesne Light has provided a forecast of the June 1 Price to Compare. The forecasts show large increases for both residential and commercial customers.

For standard residential (Rate RS) customers, Duquesne Light expects that the Price to Compare will increase 26 percent to 8.32 cents per kilowatt-hour (kWh), from the current 6.59 cents per kWh.

For commercial customers in Rate Class GS, Duquesne Light expects the Price to Compare will increase 11 percent to 6.58 cents per kWh, from the current 5.93 cents per kWh.

For commercial customers with demands under 25 kW in Rate Class GM, Duquesne Light expects the Price to Compare will increase 11 percent to 6.81 cents per kWh, from the current 6.16 cents per kWh.

For commercial customers with demands from 25 kW to 300 kW in Rate Class GM, Duquesne Light expects the Price to Compare will increase 36 percent to 7.66 cents per kWh, from the current 5.62 cents per kWh.

For commercial customers with demands under 25 kW in Rate Class GMH, Duquesne Light expects the Price to Compare will increase 11 percent to 6.84 center per kWh, from the current 6.17 cents per kWh.

For commercial customers with demands from 25 kW to 300 kW in Rate Class GMH, Duquesne Light expects the Price to Compare will increase 40 percent to 7.42 cents per kWh, from the current 5.38 cents per kWh.
