The PUC has a web site where you can compare your current rate with the rates offered by other suppliers. Go to http://www.papowerswitch.com/
and select “Shop for Electricity” at the top. Just like shopping for, say, cell phone service, some suppliers may offer a lower rate but require a locked-in contract or charge cancellation fees. If you see a lower supplier that appeals to you, you can contact them to have them take over as your electric supplier. You’ll get a confirmation letter in the mail, but you shouldn’t have to do anything else. You will still get bills from Duquense Light and Duquense Light will be still be responsible for all line maintenance.
There’s no guarantee that switching suppliers will save money, but it might. It is a pretty easy process. It can also be used to pursue an environmental agenda, if you wish. For example, one supplier might generate some of its electricity from renewable sources. You may prefer that over a supplier that operates nothing but coal-burning power plants. Part of my decision to switch to First Energy, for example, was the fact that they operate several nuclear power plants, and I like that.
