Illinois Residential Electric Rates

illinois electric rates per kwh

The Illinois Commerce Commission oversees electricity choice in Illinois.  The local utility companies continue to deliver power and send you your monthly electric bill even after you choose a competitive supplier.  If you do not choose a supplier, you pay a default rate known as the Price to Compare.

If competitive rates are below your utility’s Price to Compare, then you will save money on your electric bill.

Illinois Energy Market Overview

Energy freedom for Illinois customers came in 1997 when the Illinois Commerce Commission approved state energy deregulation. Since then, more than 1.67 million residential and over 75% of commercial and industrial customers switched energy providers. 

As a result of this impressive adoption rate, the average cost of electricity in Illinois is very close to the US average (13.32 compared to 13.04 ¢/ kWh) for residential customers and below average for commercial customers (9.01 compared to 10.57¢/ kWh ); despite being the US fifth most populous state. 

The high demand for cheaper energy has also contributed to a large number of electricity and natural gas suppliers, competing for the attention of Illinois customers. If you live in Illinois and you haven’t yet switched, read on to find out all you need to know about how to get the ball rolling.
