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

    The Commission audits budget information from North Shore Gas, asks North Shore Gas to defend and update figures provided.

    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.
