Energy Waste Reduction Potential Study

2016 PA 341, Sec. 6t requires the Commission, among other things, to conduct an assessment of the potential for energy waste reduction in this state and identify what is economically and technologically feasible, as well as what is reasonably achievable. The results of the energy waste reduction potential study are to inform modeling assumptions for utilities to integrate into their IRP proceedings.

The formal portion of the statewide IRP modeling assumption process is scheduled to begin August 18, 2017 and conclude by December 18, 2017. The informal portion of this stakeholder outreach effort will begin immediately and conclude in July 2017 with the submission of a draft staff proposal to be filed in the IRP Modeling Parameters docket once it is initiated.  

Staff will seek input through follow-up discussions and meetings with stakeholders on approaches to meeting these requirements, including how best to leverage existing energy waste reduction potential studies.


Staff Lead

Patricia Poli



  • Completed a statewide energy waste reduction potential study in August the with stakeholder input
  • Three stakeholder meetings
    • One of these meetings was a session with LBNL
  • Incorporated into the larger IRP scenarios and assumptions report
