But, again, the concept isn’t difficult. Let’s use the city of Joliet as an example. Joliet’s traditional utility for the 60435 area code is Commonwealth Edison. As of late February, its price to compare is 7.195 cents per kilowatt hour (kWh); at this writing, four plans from ChooseEnergy.com featured suppliers with lower rates, including one that’s 18% cheaper and uses all green energy.
Variable Rate: With a variable rate, you stand closer to the fire. Rather than keep your costs separate from market conditions, you experience the rise and fall of price alongside your provider. You profit when supply exceeds demand, but could pay through the nose if the electricity grid becomes overtaxed. That usually means a higher bill in the summer and winter (when demand is at its highest) and a lower one in the fall and spring. A variable rate plan is best for people interested in staying on top of market changes – when prices get too exorbitant, there’s no contract and no cancellation fee if you want to try a new provider.
Ultimately, the main difference between an electricity provider and an electric utility comes down to what they service and how. Electricity providers deal with purchasing and marketing electricity to customers. Electric utilities handle the poles and wires that service your home. Separating these roles means customers can shop for a competitive electricity rate and still receive reliable electric service.
Prior to electricity deregulation in select areas of the United States, the electricity that powered homes and businesses came from the utility company and customers could not compare electricity providers. With electricity deregulation continuing to expand and electricity providers in the mix, residents and businesses should be sure to understand where their electricity comes from, how it’s delivered, and how the cost is divided.

If you’re on a fixed rate tariff with your current supplier, check to see if there’s an exit fee for leaving the contract early. If there is, you’ll need to factor this cost into your price comparison as it could swallow up some of the potential savings. If you can supply your tariff name when you get a quote, we can take your tariff into account when showing you the savings you could make.
