Businesses in and around Pittsburgh, Pennsylvania, will see 10% higher electric rates starting December 1 if they continue to buy their power supply from Duquesne Light.

That's because Duquesne Light will increase its Price to Compare, the electric rate charged to customers who do not shop for an alternate electric supplier, and who instead take "default" electric supply from Duquesne Light.  The new Prices to Compare will generally be in effect from December 1, 2014 to May 31, 2015.

Starting December 1, the Duquesne Light Price to Compare for General Service Small (GS) customers will increase to 7.27¢/kWh, from the current 6.67¢/kWh.

The Duquesne Light Price to Compare for General Service Medium class customers with demands under 25 kW (GM <25 kW) will increase to 7.46¢/kWh on December 1, from the current 6.86¢/kWh.

The Duquesne Light Price to Compare for General Service Medium class customers with demands over 25 kW (GM >25 kW) will increase to 8.24¢/kWh on December 1, from the current 8.14¢/kWh.

For Duquesne Light customers in the General Service Medium Heating class with demands under 25 kW (GMH <25 kW), the Price to Compare will increase to 7.45¢/kWh, from the current 6.85¢/kWh.

For Duquesne Light customers in the General Service Medium Heating class with demands over 25 kW (GMH >25 kW), the Price to Compare will increase to 7.87¢/kWh, from the current 7.77¢/kWh.

Residential customers at Duquesne Light will also see a negligible increase in the Price to Compare on December 1, to 8.09¢/kWh from the current 8.08¢/kWh.

The Price to Compare is only paid by customers who continue to buy their electricity supply from Duquesne Light instead of shopping for a competitive electric supplier, and therefore the Price to Compare serves a benchmark when shopping.

As of October 2014, some 44% of commercial customers and 65% of industrial customers at Duquesne Light have switched to a competing electric supplier.  Some 40% of residential customers have also shopped for an alternative electric supplier at Duquesne Light.

Duquesne Light is the local utility for more than 500,000 customers in the Pittsburgh area.
