Michigan Multi-Site Cannabis Operator Energy: Queue Strategy Across DTE and Consumers

One state, two utilities, zero open choice allotments

Michigan looks deregulated on paper because PA 141 of 2000 opened retail access [mpsc-choice-2025-report]. PA 286 of 2008 capped it at 10 percent of each utility's prior-year weather-adjusted sales [mcl-460-10a]. In 2025 the program carried 2,172 MW across 5,517 customers with 5,101 waiting [mpsc-choice-2025-report].

An MSO with a Class C grow in Warren (DTE), three dispensaries in Grand Rapids (Consumers), and a processor in Lansing (Consumers) is managing:

• Two separate choice queues
• Two rate books with different demand structures
• One MISO Zone 7 footprint (for DTE and Consumers)
• Utility full service at every site until an allotment opens

See multi-state operator procurement strategy for portfolio concepts adapted here.

Territory split

Utility	Cannabis density	Key rate schedules
DTE Electric	Detroit metro, Thumb	D3 dispensary, D4 grow, D11 primary grow
Consumers Energy	Grand Rapids, Lansing, Flint, Kalamazoo	GS dispensary, GSD grow, GPD primary

Southwest Michigan (Benton Harbor) sits on Indiana Michigan Power in PJM with the same 10 percent cap [mpsc-choice-2025-report]. Upper Peninsula facilities are rare in cannabis but face the same cap mechanics on smaller utilities.

Portfolio tracker columns

Field	Why it matters
Site and utility	DTE vs Consumers queue
Rate schedule	D4 vs D11 vs GSD vs GPD
Billing demand (12-month peak)	Demand charge exposure
Queue confirmation number	Allotment eligibility
Choice status	Full service vs AES
MPSC rate case docket	Delivery charge changes

Consumers' September 2026 tracker showed 42,004 MWh of open allotments against 5.3 million MWh of queued load [consumers-electric-choice]. Allotments are scarce. The tracker is a long-term asset.

Near-term savings: rate class before supplier

Assume two DTE grows each with 400 kW billing demand:

• Both on D4: distribution demand alone is 400 x $27.10 = $10,840/month each [dte-rate-book]
• One moved to D11 primary: distribution demand is 400 x $7.15 = $2,860/month [dte-rate-book]

One primary-voltage conversion saves roughly $8,000 per month in this example before capacity and non-capacity lines. Across a two-grow portfolio that exceeds most AES contract savings available in a capped market. At Michigan's 16.63 cents/kWh commercial average, a 6 GWh portfolio spends roughly $998,000 per year on energy alone before demand lines [eia-epm-5-6-a].

Plan primary service during buildout. Retrofit after energizing at secondary voltage is expensive.

Queue enrollment at every new account

Under MCL 460.10a utilities file rank-ordered queue lists each January 15 [mcl-460-10a]. When allotments open, the next customers have five business days to accept [mcl-460-10a]. Enrollment at service application preserves position.

DTE return-to-service rules are strict: two-year initial term on choice, December 1 notice for June-September peak return, punitive rates for late returns [dte-electric-choice]. Consumers allows one switch per month for a $5 fee [consumers-electric-choice]. An MSO should not move accounts to choice casually.

Self-Direct and portfolio efficiency

Large customers may self-direct energy-waste-reduction funds into their own projects [consumers-ee-business]. An MSO with combined load above the statutory threshold can fund LED retrofits across multiple grows under one MPSC-approved plan rather than site-by-site rebate applications.

DTE's indoor-agriculture rebates (AG-30/31, AG-35, AG-39) and Consumers AG211 require pre-notification per site [dte-ee-catalog-2026].

Submetering multi-tenant buildings

MSOs in mixed-use buildings may share a master meter. See submetering multi-tenant cannabis buildings before signing leases. Queue enrollment attaches to the account holder on the utility bill.

Licensing churn and queue position

CRA monthly reports show dozens of grower and retailer approvals per month [cra-au-licensing-reports-2026]. Industry trackers citing CRA snapshots reported 935 active grower licenses and 838 retailers as of July 23, 2026 [growgoyle-mi-q3-2026]. Acquired facilities may inherit queue position from the prior account holder or require re-enrollment depending on account structure [mcl-460-10a]. Due diligence on acquisitions must include utility account numbers and queue confirmation letters.

Benchmarking sites against Ohio portfolio peers

MSOs spanning Michigan and Ohio should separate reporting: Ohio sites bid CRES supply on June 1 SSO resets [oh-energychoice-glossary]; Michigan sites track DTE and Consumers rate cases [dte-rate-book] [consumers-large-business-rates]. Blending the two states in one cents-per-kWh KPI hides the cap constraint in Michigan.

Acquisition due diligence checklist

Buying a licensed facility requires verifying queue number, rate schedule, outstanding utility deposits, and any primary-service transformer liens [mcl-460-10a]. Sellers sometimes omit queue paperwork; request it in the data room alongside license transfer documents [cra-au-licensing-reports-2026].

Corporate sustainability reporting

MSOs publishing ESG reports should separate Michigan full-service kWh from Ohio CRES-supplied kWh [oh-energychoice-glossary]. Renewable energy certificate claims differ by supply path [growgoyle-mi-q3-2026].

Staggered contract calendar on full service

Without AES contracts, the procurement calendar shifts to MPSC rate case dates and annual budget cycles [dte-rate-book] [consumers-large-business-rates]. DTE and Consumers file rate cases on different schedules, so delivery charges at your Warren grow and your Grand Rapids stores may reset in different years. Track each docket number in the portfolio tracker and model a 3 percent delivery increase sensitivity per rate case until the order publishes [mpsc-choice-2025-report].

When one acquisition adds eight retail accounts in Consumers territory, batch queue verification calls rather than assuming seller-provided queue numbers are current [consumers-electric-choice]. Cap tracker positions change when customers ahead of you exit choice or go out of business [mpsc-choice-2025-report]. Refresh queue positions every January after utilities file updated lists [mcl-460-10a]. Portfolio managers should treat queue position like a real option with no guaranteed exercise date [mpsc-choice-2025-report]. Model zero AES savings in base-case pro formas until an allotment letter is in hand [consumers-electric-choice]. Upside scenarios can show AES savings separately in sensitivity tables [mpsc-choice-2025-report]. Board decks should label Michigan supply as capped until allotments are documented [mcl-460-10a].

Indiana Michigan Power and PJM exception

Southwest Michigan on Indiana Michigan Power sits in PJM with the same 10 percent cap [mpsc-choice-2025-report]. An MSO with Benton Harbor production and Grand Rapids retail crosses ISO and utility boundaries within one state [mpsc-choice-2025-report]. Track queue and tariff separately for I&M accounts [mpsc-choice-2025-report].

Acquisition due diligence on queue position

Buying a licensed facility requires verifying queue number, rate schedule, and transformer ownership [mcl-460-10a]. Sellers sometimes omit queue paperwork [cra-au-licensing-reports-2026]. Refresh queue positions every January after utilities file updated lists [mcl-460-10a]. Model zero AES savings in base-case pro formas until an allotment letter is in hand [consumers-electric-choice].

January 15 queue list refresh

Utilities file rank-ordered queue lists each January 15 [mcl-460-10a]. Portfolio managers should refresh queue positions immediately after filing [consumers-electric-choice] [dte-electric-choice]. Corporate reorganizations require name-change paperwork to both utility and MPSC cap administrator [mcl-460-10a].

DTE December 1 notice for peak season

MSOs with any DTE choice accounts must calendar December 1 written notice for June-September peak return [dte-electric-choice]. Late return penalties exceed typical AES savings [dte-electric-choice]. Consumers one-switch-per-month rule is simpler for retail-heavy portfolios [consumers-electric-choice].

Portfolio COGS benchmarking

Normalize utility COGS per pound across DTE and Consumers sites using the same trailing-twelve-month window [eia-epm-5-6-a]. Wide spreads often indicate rate class placement, not cultivation efficiency [dte-rate-book] [consumers-large-business-rates].

MSO playbook across DTE and Consumers

Separate queue trackers per utility [consumers-electric-choice] [dte-electric-choice]. Portfolio tracker: site, utility, class, kW, queue ID, choice status [mcl-460-10a]. D11 primary saves roughly eight thousand per month vs D4 at four hundred kW example [dte-rate-book].

January 15 queue list refresh [mcl-460-10a]. Acquisition diligence on queue letters [cra-au-licensing-reports-2026]. Ohio CRES sites use different calendar [oh-energychoice-glossary]. Zero AES savings in base pro forma [mpsc-choice-2025-report].

Refresh queue positions after January 15 filings every year [mcl-460-10a] [consumers-electric-choice].

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 [mpsc-choice-2025-report]. Update the folder after every rate case order and every June benchmark reset [consumers-electric-choice]. Facility managers should reconcile billing demand to interval peaks monthly and escalate discrepancies to the utility account manager before paying disputed invoices [dte-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 [dte-rate-book]. Legal should keep meter assignment language in leases aligned with the license holder entity on the utility account [mcl-460-10a].
