What's the Difference Between Utilities and Providers?
Utilities like UI are energy distribution companies. They operate in distinct service areas and install and maintain power lines. Also, they respond to outages and ensuring consumers get the energy they pay for. If you need to report an outage or see a downed power line, you can contact your local utility to get help.
Utilities make up only one part of a deregulated energy market. These companies receive energy from providers also known as suppliers. The suppliers are the ones that either purchase or generate the electric. Suppliers set their rates based on the current market. Then consumers choose their new rate based on preference of the agreement. This system drives competition among providers and prevents monopolies that often occur in regulated markets.
With market rates changing daily, shopping for a new rate can help you keep your costs low. United Illuminating makes it easier to compare rates with a Price to Compare. This number is a fair market cost, and it can help you decide whether a provider has a fair rate. To compare rates to the current market in your area, review the price to compare on your recent electric bill.

Comparing rates in a deregulated market can be a challenge. With so many options at your hand, how can you know you are getting a great rate? We use reverse energy auctions to help commercial clients find a low price for their usage.
To set up your auction, our team will identify a group of providers able to bid on your business. These companies want to win your contract, and they know you’re looking for a low rate, so the bids will go down over time. When the auction ends, you can discuss your options with one of our energy advisors.
