Michigan Integrated Resource Plan Comments
Sierra Club retained Synapse to review the draft parameters for Michigan’s impending IRP process proposed by the state’s governing agencies. Synapse found that, while most of the parameters were appropriate and up to standards for IRPs, Synapse identified a few areas in which changes could be beneficial for both planning participants and customers impacted by the IRP. Synapse’s comments to the Michigan Public Service Commission Staff outlined such changes, for example clarifying the relationship between the IRP process and the transmission and distribution and fuel planning processes; defining how utilities should select a preferred scenario; and modifying some modeling assumptions to better align with utility planning and ensure a more accurate, detailed, and robust analysis.
