Duquesne Light Company History
In 1880, famed Pittsburgh inventor George Westinghouse was appproached by his younger brother, Henry Herman, to back a new Pittsburgh electric utility, the Allegheny County Light Company (ACLC). Since the older Westinghouse had already been experimenting with lighting systems for his machine plants, he readily agreed. At its launching in 1882, ACLC specialized in electric arc lighting for businesses. The company soon landed the giant Pennsylvania railroad as a major customer.
By 1884, George Westinghouse owned successful businesses in both electricity and natural gas. He then formed the Philadelphia Company as a holding company to control his enterprises. The company grew rapidly, acquiring other area companies, and eventually took over ACLC in 1896.
But further expansion screeched to a halt in 1903 when a syndicate of financiers organized the assets of some 150 independent Pittsburgh area electric and traction companies (most of which no longer existed) and consolidated them into the Duquesne Light Company. While this upstart company lobbied hard for a city lighting franchise, it would take over three years before it would build its own power plant.
Eventually, the Philadelphia Company bought Duquesne Light Company in February, 1912. As part of the consolidation, the Philadelphia Company merged ACLC and its other power companies together to form a new Duquesne Light Company (DLC). At the time, it was the tenth largest utility in the U.S.
In 1935, the Public Utility Holding Company Act forced the Philadelphia Company to spin off DLC as a separate utility company. It has since expanded its transmission and distribution network throughout both Allegheny and Beaver counties in Pennsylvania. When PA Electric Choice was passed in 1996, the utility sold off its generation assests in order to become a power distribution business to comply with the new law.
Now, DLC strives to give back to the people it serves in the Pittsburgh metro area. Through its charitable giving program, the company seeks ways to enhance quality of life and contribute to the region's economic growth while also working for the protection of our environment and green spaces.

You'll need to provide the following information when you apply to start service:

Again, Duquesne Light Company needs three business days to process your service request.
If you elect not to provide a Social Security number or Tax ID, please call 412-393-7300 Monday through Friday 8 a.m. to 5 p.m. to complete your application over the phone.
Will I Need to Pay a Deposit?
Credit Rating -- DLC has the right to check your credit history and level of credit risk to determine whether a security deposit is necessary.
TIP -- Be sure to unfreeze your credit. If you have frozen your credit with any of the major credit agencies, you will need to have it temporarily unfrozen before you submit a new service request.
Pay a Deposit -- DLC must notify you in writing of the specific reasons why you are required to pay a security deposit. Deposit amounts will be based on company charges in an amount that is equal to either:
- one-sixth of the applicant's estimated annual bill
- one-sixth of the actual average annual bill for existing customers at the premises
Customers have three months to pay the deposit. The utlity can hold the deposit for 24 months. If the customer pays their bill in full and on time for 12 consecutive months, the deposit will earn interest.
Customers also have the right to use a guarantor who is a credit-worthy customer with DLC and can pay your bills if you fail to do so.
Understand DLC Delivery and Supply Charges
In Pennsylvania, residential customers pay for both the cost to deliver their electricity as well as for the amount of electricity supply that they use.
Understand DLC PTC Charges
PA PUC requires Duquesne Light to provide electricity supply at a default rate to customers in their service territory who don't shop for a retail supplier. Implementing the PTC default rates is overseen by PA PUC as these repesent generation supply costs that are passed directly through DLC onto consumers without mark up.
Price to Compare (PTC)
The PTC default rate represents the actual price the utility pays for the electricity. It includes not only the price to generate the electricity but also the cost to transmit it from power stations over high tension power lines to Duquesne Light Company's local electrical switch yards. From there, the electricity is distributed throughout the DLC local electrical grid for delivery to homes.
Each utility's PTC rates are determined every few years during auctions to line up generation supplies covering specific delivery periods. Consequently, Duquesne Light's PTC rates change every 6 months on June 1 and December 1. That means these electricity rates can vary seasonally; low some months, higher the next.
Duquesne Light Company Current PTC Residential Rate:
11.450 cents per kWh, expires 12/31/2023
NOTE: There are approximately thirty-five borough-owned public power systems in Pennsylvania. These purchase energy for their local residents. Many prohibit residents from shopping for their own provider. If you live in one of these communities, check with your local government to learn more.
How Much Do DLC PTC Charges Cost?
The Duquesne Light Company PTC rate is a weighted average rate. Business and commercial customers with higher usage have a lower PTC than residential customers. All the same, it's important for all consumers to know and understand how much they are paying for their electricity in any one month.
How much is the Duquesne Light PTC rate?
The DOE EIA estimates that the average Pennsylvania residence uses an average of 864 kWh each month. Therefore, an average PTC bill roughly breaks down like this:
Rate per 864 kWh Used | Monthly Customer Charge | Total | |
PTC Supply Rate | 11.450 cents | 0 | $98.93 |
Monthly Distribution Charges (excluding riders) | $0.060233 per kWh | $12.50 | $64.54 |
Total Bill | $163.47 |
Understand Pennsylvania Energy Choice
Pennsylvania electric consumers are free to choose their own competitive retail electricity supplier. These alternative suppliers shop deals with different producers on the wholesale market to offer competitive rates. As such, their rates are not controlled by PAPUC the same way that utilities are. This way, retail suppliers are able to offer competitively priced fixed rate plans for a variety of term lengths.
Though it can seem confusing, shopping electricity plans is an easy process. The trick is finding the one that meets your needs. That's why retail energy suppliers in Pennsylvania offer two types of plans:
