Supplier Questions — West Mifflin
What does an energy supplier do for a business in West Mifflin?
An energy supplier like Commonwealth Utilities sells the electricity and natural gas commodity used by a West Mifflin 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 West Mifflin businesses?
Duquesne Light Company's Price to Compare reflects short-term wholesale procurement for default service customers. A competitive electricity supplier can hedge West Mifflin 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 West Mifflin?
Natural gas wholesale prices and the Peoples Natural Gas purchased gas cost rate both tend to climb into heating season. For West Mifflin 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 West Mifflin 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 West Mifflin businesses really free?
Yes. The Level-1 audit is offered to any West Mifflin 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 West Mifflin?
Duquesne Light Company is the electric distribution utility and Peoples Natural Gas is the natural gas distribution utility for West Mifflin. Both are regulated by the Pennsylvania PUC. Supplier competition happens only on the generation/commodity portion of the bill.
