Deep Decarbonization & Rapid Electrification in Indiana

Energy Matters Community Coalition
Project Complete May 2022

On behalf of Energy Matters Community Coalition (EMCC), Synapse modeled a Deep Decarbonization and Rapid Electrification (DDRE) scenario as an alternative to the scenarios presented in Duke Energy Indiana's (DEI) IRP. The IRP scenarios that DEI modeled failed to account for both the deep decarbonization of the electric power sector and the rapid electrification of other sectors that will be needed to meet the goals of the Paris climate accord and to avoid the worst impacts of climate change.

We used our in-house EV-REDI and BDC models to evaluate trajectories of transportation and building electrification, and the resulting impacts on electricity consumption and on-site and tailpipe fossil fuel emissions. We also considered electric load growth from the decarbonization of the industrial sector. Incorporating these load requirements, we used the EnCompass model to develop a generation resource plan that serves the new loads from other sectors while decarbonizing the electric power sector by 75 percent by 2030 and 95 percent by 2040, relative to 2020 emissions levels. We summarized our findings in a report that was filed along with EMCC's comments on DEI's IRP.
