Overview
Michigan's solar market is served primarily by DTE Electric and Consumers Energy. Net metering programs allow systems up to 150 kW for renewables (550 kW for methane digesters). The state administers a voluntary REC market (MIREC), and projects can also sell into Ohio and Pennsylvania markets. Retail choice exists but is effectively capped at 10% of incumbent utility load, limiting practical availability.
Permitting Guide
Common Challenges & Landmines
Local moratoria + ordinance churn (solar setbacks, BESS bans, decommissioning bonds) are usually the #1 surprise cost. Stormwater + erosion compliance (CGP/SWPPP) enforcement risk + stop-work exposure. Wetlands/401/404 + floodplain can be route/site killers—plan alternatives early. BESS fire code adoption + AHJ posture: IFC/NFPA 855/UL 9540A documentation expectations vary by locality.
Tax Considerations
Property tax is commonly local and negotiable; incentives are often deal-specific.
Data Center Considerations
Incentives vary widely and often include sales/use exemptions and sometimes property tax relief.
Net Metering Programs
DTE offers residential buyback rates averaging $0.09/kWh and non-residential at $0.07/kWh, with time-of-day variations. Consumers Energy rates average $0.10/kWh residential and $0.09/kWh non-residential with seasonal variations. Both utilities cap renewable systems at 150 kW. Application fees are $50 for both utilities, with DTE charging additional interconnection fees of $500-25,000 depending on system complexity.
Interconnection Timeline
DTE interconnection typically takes approximately 20 business weeks for most residential projects. Consumers Energy offers similar timelines. The process includes application review, engineering assessment, and meter installation. Complex systems or those requiring grid upgrades may take longer.
REC Markets
Michigan administers the voluntary MIREC market for in-state REC trading. Projects can also sell into the Ohio and Pennsylvania REC markets for additional flexibility. There is no mandatory SREC market, so REC revenue is supplemental rather than a primary project driver.
Frequently Asked Questions
Why is retail choice limited in Michigan?
Michigan's retail choice is capped at 10% of each incumbent utility's load. Major utilities (DTE, Consumers Energy) have met this cap, making competitive supply options effectively unavailable for most customers. Alternative Electric Suppliers are licensed but operate within this constraint.
What are the interconnection fees?
DTE charges a $50 application fee plus interconnection fees of $500-25,000 depending on system complexity. Consumers Energy charges a $50 application fee. Both utilities require systems to meet technical standards and obtain proper inspections before permission to operate.
