Summary
Note: As of May 2024, utility-specific interconnection rules proposed by Michigan's various investor-owned utilities are currently under review by the Michigan Public Service Commission (MPSC). The new rules must incorporate changes required by Public Act 235 of 2023.
Michigan adopted new statewide interconnection standards, the MIXDG rules, in 2023.
The new interconnection standards use a five-tier system similar to previous rules, but with fast-track processes available for all tiers. The five tiers are:
- Level 1: Certified, 20 kW or less
- Level 2: Certified, 20-150 kW
- Level 3: Not certified, 150 kW or less, or 150-550 kW
- Level 4: 550 kW- 1 MW
- Level 5: Greater than 1 MW
- $300 for the pre-application report
- $100 + $1/kW for certified DERs and $100 + $2/kW for non-certified DERs for the non-export track
- $100 + $1/kW for certified DERs and $100 + $2/kW for non-certified DERs for the fast track initial review fee
- $1,000 for a fast track supplemental review
- $300 for the study track interconnection application review and scoping meeting
- $10,000 for the system impact study
- $15,000 for the facilities study
If necessary to promote grid reliability or safety, the MPSC may promulgate rules that require the use of inverters that perform specific automated grid-balancing functions to integrate distributed generation onto the electric grid.
