Clinic Senior Partner Anna Sommer of Sommer Energy, LLC and Clinic Director and Senior Researcher Liz Stanton, PhD have published three recent evaluations of Indiana electric utilities’ Integrated Resource Plans (IRP) including: Vectren Energy Delivery of Indiana, Northern Indiana Public Service Company (NIPSCO), and Indianapolis Power & Light Company (IPL). Evaluations of Duke Energy Indiana and Indiana Michigan Power IRPs and an evaluation of a 2018 update to NIPSCO's IRP are forthcoming. IRP's are filed with the Utility Commission to demonstrate that utilities’ decisions to retire and/or add electric generation resources are in the public interest. While technical, these evaluations provide an important benefit to utility customers and the Indiana public more widely.
Third-party review of these and other utilities filings is critical to vet for errors, uncover questionable or self-serving assumptions, and make hidden value-judgments transparent. Important issues found in reviewing Indiana utilities’ 2016 Plans include biases both against retiring coal generation and against adopting new efficiency measures and renewable resources.
