5 Year Distribution Plans

Scope and Background

Michigan’s aging distribution system is in need of significant investment to provide a safe, reliable and accessible distribution grid going forward all while maintaining reasonable rates for customers. In response the MPSC initiated a process to review the largest rate regulated electric utilities’ distribution planning process as outlined below.

In the first quarter of 2017, the MPSC directed DTE Electric and Consumers Energy, through rate case Orders (as linked below), to develop and submit five-year distribution investment and maintenance plans.  The intent of this directive was to increase visibility into utility distribution system needs and facilitate a comprehensive review of long-term distribution planning by the Commission, MPSC Staff, and other interested parties, with more transparency than one-year outlooks in contested rate case proceedings. 

On April 12, 2018 in Case No. U-20147, the MPSC issued an order requiring DTE and Consumers to file their final distribution plans in that docket, asked for Staff and stakeholder comments on the final plan to be filed in the same docket, and required Staff to set up a technical conference to review comments. This technical conferences took place on August 7, 2018. In a November 2018 order, the Commission addressed the Staff's September 1, 2018 recommendations and provided other guidance on the next round of distribution plans which are scheduled for the second quarter 2020. Staff will continue to engage stakeholders on these topics.  

Additionally, the MPSC ordered Indiana Michigan Power, in an order issued in Case No. U-18370 (linked below), to submit a draft 5-year distribution plan by October 31, 2018 and a final plan by May 1, 2019. Comments on this plan were submitted in the U-20147 docket. 

All comments throughout the process along with final distribution plans and Staff reports are available for review in the U-20147 Docket here:
