Frequently Asked Questions

Duke Energy Indiana Rate Case

  • A rate case is a public regulatory review process in which a utility must demonstrate to the Indiana Utility Regulatory Commission (IURC) why a proposed increase in rates is needed. This independent public process helps ensure transparency and fair rates based on the costs to serve our customers.

  • Duke Energy is obligated to provide every customer in our service area with reliable electricity at rates approved by the IURC. In exchange, the utility is allowed the opportunity (not a guarantee) to earn a fair return for investors. Even though our regulators will ultimately determine any changes to customer rates, we pledge to do our part to keep rates as reasonable as possible.

  • First, Duke Energy must demonstrate to the IURC why the rate increase is needed. The Office of Utility Consumer Counselor and other interested stakeholders review our filings and vet the company's request. The commission then thoroughly reviews our request and holds public hearings to allow customers to comment. In the fall the commission will hold field hearings where the public has an opportunity to comment. In late 2019 or early 2020 the commission also will conduct public hearings and consider our written and oral testimony, along with viewpoints from others representing customer groups and other stakeholders.
