Jurisdictional electric utilities are required to submit Integrated Resource Plans (IRPs) every three years according to Indiana Code ยง 8-1-8.5-3(e)(2). The IRPs are subject to a rigorous stakeholder process. IRPs describe how the utility plans to deliver safe, reliable, and efficient electricity at just and reasonable rates. Further, these plans must be in the public interest and consistent with state energy and environmental policies. Each utility’s IRP explains how it will use existing and future resources to meet customer demand. When selecting these resources, the utility must consider a broad range of potential future conditions and variables and select a combination that would provide reliable service in an efficient and cost-effective manner.
The following utilities must submit IRPs to the Commission. Click on the utility names below to find the utilities’ most recent IRPs, comments received about the plans, and the RPP Division’s Final Report on each IRP. IRPs older than the most recent submitted versions can be found on the IRP archive page here.
Questions regarding IRPs should be directed to the Commission's Research, Policy, and Planning Division at (317) 232-2736 or via email.
