Best time to switch electric companies in Naperville, Illinois?

Determining the ideal time to switch energy providers in Naperville requires careful consideration of market trends and seasonal price fluctuations.

You'll want to review your current rates during spring and fall when energy prices typically stabilize between peak seasons.

Before making a switch, you should:

Naperville's deregulated electricity market

Since Illinois deregulated its electricity market in 1997, you've had the power to choose your electricity provider from multiple Alternative Retail Electric Suppliers (ARES).

The system works through a split structure where utilities like ComEd and Ameren Illinois maintain the power lines while ARES compete to sell you electricity.

You'll receive two main services:

• Delivery (from your utility company)
• Supply (from your chosen ARES or utility)

The Illinois Commerce Commission oversees the market to guarantee fair competition, while the Illinois Power Agency helps secure competitive rates.

You can choose between fixed rates, variable rates, or green energy options through municipal aggregation programs.
