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