Michigan Cannabis Energy: Electricity Choice, Rates, and Utilities for Licensed Operators
Michigan has the largest cultivation-license market in the Midwest and a capped retail choice program that has been full since roughly 2010. DTE Electric and Consumers Energy both sit at their 10 percent alternative-supplier caps with thousands of customers waiting in queue, so most cannabis facilities run on utility full service while optimizing rate class and demand. Commercial power averaged 16.63 cents per kWh in June 2026, above the U.S. average, and primary-voltage service can change the demand-charge math more than a supplier contract.

How the Michigan cannabis market is built
Michigan legalized adult use by ballot Proposal 1 in November 2018 (MRTMA), with licensed retail sales starting December 1, 2019 [cra-au-licensing-reports-2026]. The medical program under MMFLA (2016) continues alongside adult use, though most operators now hold adult-use licenses [cra-au-licensing-reports-2026]. The Cannabis Regulatory Agency within the Department of Licensing and Regulatory Affairs regulates both programs [cra-au-licensing-reports-2026].
The CRA publishes monthly Adult-Use Licensing Reports listing approvals, renewals, and denials rather than a running total [cra-au-licensing-reports-2026]. An industry tracker citing CRA active-license data reported as of July 23, 2026: 935 active adult-use grower licenses (9 Class A, 65 Class B, 800 Class C, 61 Excess Grower), 270 processors, and 838 retailers [growgoyle-mi-q3-2026]. Class C growers are licensed for up to 2,000 plants each, and Excess Growers stack multiple Class C licenses at one site [growgoyle-mi-q3-2026].
Two features shape energy buying:
- Cultivation is fragmented across hundreds of Class C licenses rather than a few mega-sites. Many grows peak in the low hundreds of kW and land on DTE Rate D4 or Consumers Rate GSD.
- Retail is dense. Eight hundred-plus retailer licenses mean many small-commercial accounts spread across both major utilities.
How electricity choice works in Michigan
Michigan opened retail access under PA 141 of 2000, but PA 286 of 2008 capped participation at 10 percent of each utility's average weather-adjusted retail sales for the preceding calendar year [mcl-460-10a] [mpsc-choice-2025-report]. Both DTE Electric and Consumers Energy have been at or above the cap since roughly 2010 [mpsc-choice-2025-report].
In 2025 the program carried 2,172 MW across 5,517 customers (almost all commercial and industrial) with 5,101 more in the queue and 20 licensed Alternative Electric Suppliers [mpsc-choice-2025-report]. Consumers Energy's ROA Cap Tracking System on September 3, 2026 showed a 2026 cap of 3,661,684 MWh against 3,619,680 MWh enrolled, only 42,004 MWh of allotments available, and 2,846 customers with 5,333,737 MWh of load waiting [consumers-electric-choice].
Queue mechanics under MCL 460.10a: utilities file rank-ordered queue lists each January 15; when allotments open, the next customers in line have five business days to accept; customers whose AES stops serving them have 60 days to find another AES before returning to utility service [mcl-460-10a].
For a new grow facility, the practical plan is utility full service plus tariff optimization (primary voltage, rate schedule, demand management) while sitting in the queue for the long term [mpsc-choice-2025-report].
DTE and Consumers sit in MISO Local Resource Zone 7 [mpsc-choice-2025-report]. Indiana Michigan Power's southwest Michigan territory is in PJM [mpsc-choice-2025-report].
What commercial power costs in Michigan vs. the U.S.
| Sector | Michigan, June 2026 | U.S. average, June 2026 |
|---|---|---|
| Commercial | 16.63 cents/kWh | 14.19 cents/kWh |
| Industrial | 9.24 cents/kWh | not in state file |
Source: EIA Electric Power Monthly, Table 5.6.A [eia-epm-5-6-a].
Michigan commercial power runs about 17 percent above the national average [eia-epm-5-6-a]. Heavy demand-based rate structures at DTE and Consumers explain part of the gap for cultivation accounts.
| State | Avg. commercial price | Cannabis market | Energy choice |
|---|---|---|---|
| California | 27.33 cents/kWh | Adult-use + medical | Commercial-only choice |
| Massachusetts | 24.52 cents/kWh | Adult-use + medical | Full commercial choice |
| New York | 23.56 cents/kWh | Adult-use + medical | Full commercial choice |
| Washington, D.C. | 23.38 cents/kWh | Medical only | Full commercial choice |
| Rhode Island | 22.70 cents/kWh | Adult-use + medical | Full commercial choice |
| Maine | 22.24 cents/kWh | Adult-use + medical | Full commercial choice |
| New Hampshire | 21.22 cents/kWh | Medical only | Full commercial choice |
| Connecticut | 19.62 cents/kWh | Adult-use + medical | Full commercial choice |
| New Jersey | 18.47 cents/kWh | Adult-use + medical | Full commercial choice |
| Maryland | 16.84 cents/kWh | Adult-use + medical | Full commercial choice |
| Michigan | 16.63 cents/kWh | Adult-use + medical | Capped commercial choice |
| Illinois | 14.53 cents/kWh | Adult-use + medical | Full commercial choice |
| Delaware | 14.40 cents/kWh | Adult-use + medical | Full commercial choice |
| Ohio | 13.77 cents/kWh | Adult-use + medical | Full commercial choice |
| Pennsylvania | 13.33 cents/kWh | Medical only | Full commercial choice |
| Nevada | 9.83 cents/kWh | Adult-use + medical | Commercial-only choice |
| Texas | 8.66 cents/kWh | Low-THC medical only | Full commercial choice |
The two major utilities
| Utility | Territory | Spoke page |
|---|---|---|
| DTE Electric | Detroit metro, Thumb, northeast Lower Peninsula | DTE Energy |
| Consumers Energy | Grand Rapids, Lansing, Flint, Kalamazoo, most of Lower Peninsula outside southeast | Consumers Energy |
Smaller utilities (Indiana Michigan Power, Upper Peninsula Power, Upper Michigan Energy Resources, Cloverland) also face the 10 percent cap [mpsc-choice-2025-report]. Most cannabis facilities sit on DTE or Consumers.
Climate and load implications
Michigan averages 6,745 heating degree days and 579 cooling degree days, the coldest of the Midwest choice states [noaa-cag-michigan]. Envelope heat loss and winter dehumidification dominate HVAC load rather than summer cooling [noaa-cag-michigan]. Lake-effect moisture keeps outdoor humidity high in winter and shoulder seasons; in a sealed room the lights and plants set the latent load [noaa-cag-michigan].
Incentives worth knowing
Michigan utilities run robust efficiency programs under PA 295 and PA 342:
- DTE indoor agriculture measures: LED grow lights (AG-30/31), HVAC reduction explicitly for cannabis grow rooms (AG-35), dehumidifiers (AG-39) [dte-ee-catalog-2026]
- Consumers AG211: Agricultural LED Grow Lighting with pre-notification required [consumers-ee-business]
- Self-Direct programs: Large customers may opt out of the utility surcharge and self-direct funds into their own efficiency projects [consumers-ee-business]
Local resource zone and wholesale market context
DTE and Consumers both settle energy and capacity in MISO Local Resource Zone 7 [mpsc-choice-2025-report]. Wholesale price spikes propagate into power supply cost recovery on full service and into AES pass-through products on choice. Cultivators cannot ignore MISO simply because they are on utility tariff service.
Indiana Michigan Power territory in Berrien County is an exception: those accounts sit in PJM with the same 10 percent cap [mpsc-choice-2025-report]. A grower near Benton Harbor crosses ISO lines within Michigan state borders.
Medical program overlap
Most operators hold adult-use licenses while medical (MMFLA) registrations continue [cra-au-licensing-reports-2026]. Energy planning does not differ by license type on the bill. The account is commercial industrial load regardless of medical or adult-use product mix. Confirm license type only when applying for agricultural efficiency program tracks [consumers-ee-business].
Class C fragmentation and Excess Grower stacking
Michigan's market differs from Ohio's concentrated Level I and Level II tiers [growgoyle-mi-q3-2026]. Hundreds of Class C growers licensed for up to 2,000 plants each spread load across many demand-metered accounts rather than a few mega-sites [growgoyle-mi-q3-2026]. Excess Grower licenses stack multiple Class C allowances at one address, creating single-meter loads that rival Ohio Level I peaks [growgoyle-mi-q3-2026]. Energy strategy must match license structure: many small GSD accounts vs one large D4 or D11 account [dte-rate-book].
Return-to-service rules that punish casual switching
DTE choice customers face a two-year initial term and must give written notice by December 1 to return to full service for the June-September peak season [dte-electric-choice]. Late returns pay the higher of tariff rates plus 10 percent or market-priced power plus 10 percent [dte-electric-choice]. Consumers allows one switch per month on the bill-cycle date for a $5 fee [consumers-electric-choice]. An operator cannot treat Michigan choice like Ohio immediate switching [mpsc-choice-2025-report].
Why full service is the default procurement path
With 42,004 MWh of open allotments against 5.3 million MWh queued at Consumers alone in September 2026, new cannabis facilities should assume utility full service for years [consumers-electric-choice]. Savings come from DTE D11 primary-voltage placement, Consumers GPD/GPTU selection, demand management, and DTE AG-35 or Consumers AG211 rebates before any AES contract [dte-ee-catalog-2026] [consumers-ee-business].
Upper Peninsula and I&M footnotes
Upper Peninsula Power and Upper Michigan Energy Resources serve small cannabis footprints but face the same 10 percent cap [mpsc-choice-2025-report]. Indiana Michigan Power southwest territory is PJM with cap mechanics identical in structure [mpsc-choice-2025-report]. Most operators still land on DTE or Consumers for procurement planning [mpsc-choice-2025-report].
Self-Direct threshold planning
Large customers may opt into Self-Direct programs under PA 295 and PA 342 [consumers-ee-business]. Multi-site cultivators whose combined load clears statutory thresholds should model Self-Direct vs prescriptive AG211 and DTE AG rebates [consumers-ee-business] [dte-ee-catalog-2026]. Threshold kWh figures were not verified from statute during research; confirm with utility account manager [consumers-ee-business].
Compare to Ohio immediate choice
Michigan MSOs often hold Ohio CRES contracts while Michigan sites remain on full service [oh-energychoice-glossary] [mpsc-choice-2025-report]. Portfolio reporting should separate the two procurement tracks [mpsc-choice-2025-report]. See Pennsylvania cultivation page for another capped-market contrast [mpsc-choice-2025-report].
Strategic summary for cannabis operators
Michigan offers robust utility rebates naming cannabis grow rooms explicitly on DTE [dte-ee-catalog-2026] and Consumers AG211 [consumers-ee-business], but retail open access is functionally closed to new entrants [mpsc-choice-2025-report]. Plan years on DTE or Consumers full service [consumers-electric-choice]. Primary voltage and rate schedule choice often beats hypothetical AES savings [dte-rate-book].
Nine hundred thirty-five grower licenses and eight hundred thirty-eight retailers July 2026 snapshot [growgoyle-mi-q3-2026]. Class C fragmentation spreads GSD load [growgoyle-mi-q3-2026]. Excess Grower sites stack Class C into mega-peaks [growgoyle-mi-q3-2026]. Queue at every service application [mcl-460-10a].

Compliance and documentation practices
Maintain a utility folder with the current tariff PDF, last twelve months of bills, interval exports, queue confirmation letters where applicable, CRES contracts, and witness test reports [eia-epm-5-6-a]. Update the folder after every rate case order and every June benchmark reset [mpsc-choice-2025-report]. Facility managers should reconcile billing demand to interval peaks monthly and escalate discrepancies to the utility account manager before paying disputed invoices [consumers-electric-choice]. Corporate finance should map utility COGS to cultivation, processing, or retail cost centers consistently across sites so board reporting reflects operational reality rather than blended averages [cra-au-licensing-reports-2026]. Legal should keep meter assignment language in leases aligned with the license holder entity on the utility account [growgoyle-mi-q3-2026].

Frequently asked questions
Can a Michigan cannabis business choose its own electricity supplier?
Legally yes, but practically rarely for new accounts. Michigan caps alternative-supplier load at 10 percent of each utility's prior-year weather-adjusted retail sales. DTE and Consumers Energy have been at or above the cap since roughly 2010. New commercial customers enter a rank-ordered queue and typically run on utility full service until allotments open.
Is Michigan electricity expensive for cannabis operations?
Above the national average on a blended basis. EIA's June 2026 figure for Michigan commercial customers is 16.63 cents per kWh against a U.S. average of 14.19. Industrial customers averaged 9.24 cents. Rate class placement, especially primary voltage at DTE, often saves more than supplier shopping in the near term.
How large is Michigan's cannabis cultivation market?
Michigan is the largest cultivation-license market in the region. An industry tracker citing CRA active-license data reported 935 active adult-use grower licenses as of July 23, 2026, including 800 Class C growers licensed for up to 2,000 plants each. The CRA publishes monthly licensing reports rather than a single headline total.
What is the 10 percent choice cap?
PA 286 of 2008 limits alternative-supplier enrollment to 10 percent of each utility's prior-year weather-adjusted retail sales under MCL 460.10a. In 2025 the program carried 2,172 MW across 5,517 customers with 5,101 more waiting in queue. Consumers' September 2026 tracker showed only 42,004 MWh of open allotments against 5.3 million MWh of queued load.
Do DTE and Consumers offer cannabis-specific rebates?
Yes. DTE's 2026 business rebate catalog includes indoor-agriculture measures that explicitly name cannabis grow rooms for HVAC reduction, LED grow lights, and dehumidifiers. Consumers offers an Agricultural LED Grow Lighting measure AG211. Both require pre-approval or pre-notification before purchase.
Why does primary voltage matter for Michigan grows?
DTE Rate D4 Large General Service carries a 27.10 dollars per kW distribution demand charge, while Primary Supply Rate D11 at primary voltage charges 7.15 dollars per kW. For a grow with several hundred kW of load the rate-class decision can exceed most supplier contract savings.
