Assembly Bill 1177 mandates that public utilities providing retail electric services in Wisconsin must notify their customers when they file a general rate case application with the Public Service Commission (PSC). The required notice must inform customers that the utility has requested a rate change, detail the anticipated dollar and percentage impact on average residential and commercial bills, and indicate where copies of the application can be inspected. Additionally, the notice must explain that further details about the proposed rate changes are available upon request. This notification process must begin upon filing the rate case application and continue for 60 days after the PSC issues its final order.

The bill specifies that the notice must be made available on the utility's website and through a publication method used to deliver customer bills. The information in the notice will initially describe the rate case application and will be updated to reflect the PSC's final order once it is issued. This legislation aims to enhance transparency and communication between electric utilities and their customers regarding rate changes.
