How a rate review works

The rate review process takes time — about 18 months from developing the review to the time new energy rates take effect.

Rate review process

1. Rate review preparation
   North Shore Gas analyzes budgets, sales and construction forecasts and develops the rate review.
2. Filing
   North Shore Gas files rate review with the Illinois Commerce Commission.
3. Review
   The Commission audits budget information from North Shore Gas, asks North Shore Gas to defend and update figures provided.
4. Hearings
   The public has an opportunity to comment. Witnesses that support the figures in the rate review are available for cross examination in a court-like proceeding.
5. Ruling
   The Commission decides any outstanding matters and issues a written order on the rate request.
6. Rates take effect
   New rates take effect for customers.
