An IL electric rate is available from not just the old monopoly electric utility in Illinois but by multiple other alternate electric companies. Now that Illinois is deregulated you have some options for who you choose to provide your electrci service.
Your electric utility will still be the same pole and wires company you have always used by you can compare electric rates in Illinois and find the cheapets one you can find.
The key to comparing IL electric rates accurately is to not fall for common scams. The most common scam is to offer a competitive electric rate for the first month and then jack the rate up after the first month.
As you can see a variable month to month rate allows the ability for an IL electric provider to make a rate look good to begin with only to charge you much higher for that same price when the first month rate expires.
You usually will not know that the price has jumped until you have accumulated a month in electricity charges.
Because of these issues be sure to compare fixed IL electric rates and don’t fall for a cheap looking 1 month rate.
