MPSC Statewide Energy Assessment (SEA)

Notice: MI Power Grid meetings and all other MPSC workgroup meetings will be conducted via teleconference only until further notice. Please find remote access information for upcoming meetings on our calendar of events. We apologize for any inconvenience this may cause.

Michigan experienced historically extreme cold weather from January 29, 2019 to February 1, 2019 due to a polar vortex. During this time, Consumers Energy asked natural gas customers to reduce usage and lower thermostats after a fire at its largest natural gas storage facility. In addition, both Consumers Energy and DTE Electric were called upon to ask their electric customers to curtail electricity usage to respond to regional constraints in electricity production across the Midwest. These events prompted the Governor to send a letter requesting the MPSC to undertake a statewide review of the supply, engineering, and deliverability of natural gas, electricity, and propane systems, as well as contingency planning related to those systems.

On February 7, 2019, the MPSC issued an order in case number U-20464 to implement the Governor’s request. The initial report was filed in the docket on July 1, 2019. Following examination of the initial report and consideration of comments, the Commission issued a final Assessment on September 11, 2019. 

The final Assessment provides 37 MPSC jurisdictional and 15 non-jurisdictional recommendations for improving the safety and reliability of Michigan’s energy infrastructure.  In recognition of some key recommendations with potential for the most impactful improvements, the Commission provided direction for additional expectations in several existing dockets and also opened several new dockets to initiate action. These Assessment related dockets include:
