HEA 1278 Energy Study

The Indiana General Assembly in House Enrolled Act 1278 (2019) tasked the Indiana Utility Regulatory Commission (“Commission”) with conducting a study of the statewide impacts of transitions in fuel sources and other electric generation resources, as well as the impacts of new and emerging technologies impacting electric generation and distribution infrastructure, on electric generation capacity, system reliability, system resilience, and the cost of electric utility service for consumers.  As part of this study, the State Utility Forecasting Group will be modeling future scenarios, and the Commission and its staff sought input.

A stakeholder meeting was held on August 22, 2019, at 1:00 p.m., in IURC Room 222 (located on the mezzanine level of the PNC Center), 101 W. Washington Street, in downtown Indianapolis.  Dr. Doug Gotham from the State Utility Forecasting Group provided an overview of his modeling system, including its capabilities and limitations. Following his presentation, Commission staff and Dr. Gotham were on-hand to answer any questions regarding the modeling or scenario development process.

After the August 22nd stakeholder meeting, Commission staff requested that stakeholders provide input regarding key scenario variables and sensitivities. Commission staff will be providing strawman draft scenarios to submit for public comment. The strawman draft scenarios and all written stakeholder comments will be posted below.

Comments on Energy Study Methodologies

As part of this study, the Commission is working with the State Utility Forecasting Group (SUFG), which is studying transitions in fuel sources, primarily modeling future scenarios; the U.S. Department of Energy National Laboratory, Lawrence Berkeley (LBNL),  which is studying new and emerging technologies, including the potential impact of such technologies on local grids or distribution infrastructure; and Indiana University, which will prepare an analysis of local economic, fiscal, and social impacts of the transition in generation resources, particularly on rural communities. The documents related to each part of the study can be found here:

Commission staff requested that if any agency/organization has comments or feedback relating to these documents, to please provide them by Feb. 21, 2020. Comments received on energy study methodologies can be found below.
