Energy Supplier for Pittsburgh Businesses
Pittsburgh's commercial buildings — from downtown high-rises and the Strip District's warehouses to riverfront industrial sites — face some of the most varied energy loads in Pennsylvania. With Duquesne Light as the local electric distribution utility and Peoples Gas as the primary natural gas distributor, Pittsburgh businesses can shop separately for their electricity supplier and natural gas supplier under PA's deregulated market, often locking in rates below the utility default Price to Compare.
Commonwealth Utilities is based at 322 N Shore Dr in Pittsburgh and treats your Pittsburgh building as one account, not two commodities. The free Level-1 audit looks at kWh waste, therm waste, and the rate structure of both — and recommends the combined supplier agreement that makes sense for your facility.


Electricity Supplier for Pittsburgh Businesses
As Pittsburgh's electric distribution utility, Duquesne Light delivers power to every commercial and residential account in the city — but the generation portion of the bill is fully open to competition. Pittsburgh businesses that rely on Commonwealth Utilities for electricity supplier frequently cut kWh costs compared to the Duquesne Light Price to Compare, especially for buildings with high daytime loads in Oakland, Downtown, and the South Side.

Supplier Questions — Pittsburgh
What does an energy supplier do for a business in Pittsburgh?
An energy supplier like Commonwealth Utilities sells the electricity and natural gas commodity used by a Pittsburgh commercial facility. Duquesne Light Company continues to deliver electricity and Peoples Natural Gas continues to deliver natural gas — only the generation/supplier line on the bill changes.
How does an electricity supplier beat the Duquesne Light Company Price to Compare for Pittsburgh businesses?
Duquesne Light Company's Price to Compare reflects short-term wholesale procurement for default service customers. A competitive electricity supplier can hedge Pittsburgh commercial kWh load on longer-term wholesale contracts and pass the fixed rate through — typically beating the PTC on a fixed-rate term.
Why lock a natural gas supplier rate before winter in Pittsburgh?
Natural gas wholesale prices and the Peoples Natural Gas purchased gas cost rate both tend to climb into heating season. For Pittsburgh commercial facilities with substantial heating or process-heat load, a fixed per-Mcf supplier agreement locked before November insulates Q1 bills from those seasonal spikes.
Does switching suppliers in Pittsburgh disrupt service or emergency response?
No. Duquesne Light Company continues to deliver electricity and respond to outages, and Peoples Natural Gas continues to deliver natural gas and respond to leak calls, regardless of your supplier choice. Switching is a billing change only.
Is the free Level-1 audit for Pittsburgh businesses really free?
Yes. The Level-1 audit is offered to any Pittsburgh commercial facility with no obligation to sign a supplier agreement. The audit identifies where the building is wasting energy on both the electric and natural gas side, which is what lets Commonwealth Utilities quote a supplier that actually fits.
Which Allegheny County utilities deliver energy in Pittsburgh?
Duquesne Light Company is the electric distribution utility and Peoples Natural Gas is the natural gas distribution utility for Pittsburgh. Both are regulated by the Pennsylvania PUC. Supplier competition happens only on the generation/commodity portion of the bill.
