Understanding Energy Choice in Ann Arbor
Energy supply in Ann Arbor is shaped by Michigan's unique regulatory structure. DTE Energy serves as the primary utility for both electricity and natural gas delivery. Michigan allows natural gas customer choice, meaning residents and businesses can purchase gas from alternative suppliers while DTE continues to deliver it. Electric choice is more limited, with a capped portion of the market open to alternative suppliers, mainly larger commercial customers.
Ann Arbor is also exploring a sustainable energy utility that could provide residents with local solar and battery options. Understanding these choices can help customers save money and support clean energy goals. Here are ten of the top energy suppliers and programs serving Ann Arbor.

Energy Supply Trends in Ann Arbor
Price stability is a top concern for many customers. Natural gas prices can fluctuate significantly with weather and global markets, leading some households to explore fixed-rate plans. However, customers should compare offers carefully against utility rates before switching.
Clean energy demand is also growing. Residents increasingly want renewable electricity, community solar access, and options for electrification. The city's sustainability initiatives are encouraging innovation and new models for local energy supply.
How to Choose an Energy Supplier
Compare prices per unit, contract length, cancellation fees, and whether rates are fixed or variable. Check whether a supplier is licensed by the Michigan Public Service Commission and review complaint histories. Be cautious of door-to-door sales pitches that pressure you to sign quickly.
Consider efficiency first. Reducing energy usage through insulation, efficient appliances, and smart controls often provides the most reliable savings regardless of supplier.
Frequently Asked Questions
Can I choose my electricity supplier in Ann Arbor?
Michigan's electric choice program is capped, so only a limited portion of electricity sales can be served by alternative suppliers, and space is typically filled by larger commercial customers. Most residential customers receive electricity supply from DTE Energy.
Will switching gas suppliers save me money?
Not always. Alternative supplier rates can be higher or lower than utility rates depending on market conditions and plan terms. Fixed-rate plans can provide predictability, but compare the total cost per unit and fees before signing a contract.
Will my service change if I switch suppliers?
No. DTE continues to deliver gas, read meters, and respond to emergencies regardless of your supplier. Only the supply portion of your bill changes.
How can I verify an energy supplier is legitimate?
Check that the supplier is licensed with the Michigan Public Service Commission. Review its complaint history and read contract terms carefully. Never share account information with unsolicited sales representatives unless you have verified their identity.
What is the best way to lower energy bills?
Energy efficiency improvements usually deliver the most dependable savings. Sealing air leaks, adding insulation, upgrading to efficient heating systems, and using smart thermostats can reduce usage regardless of your supplier.
