DTE and Consumers Energy 2026 Rate Increases: Michigan Grows That Cannot Access Choice

Two approvals, one constrained market

Michigan cannabis cultivators faced back-to-back regulated rate increases in 2026 with limited ability to shop supply. The Michigan Public Service Commission approved $242.4 million in additional revenue for DTE Electric, effective March 5, 2026 [mpsc-dte-2026]. Two months later, the MPSC approved $276.6 million for Consumers Energy, effective May 1, 2026 [mpsc-consumers-2026].

Meanwhile, Michigan's electric choice program stayed fully subscribed in 2025, with 5,101 customers in the queue waiting for choice capacity [mpsc-choice-2025]. Most new cultivation facilities cannot enroll in competitive supply. They pay the regulated tariff that these rate cases increased.

What each approval covers

Utility	Approved revenue	Effective date	Service territory
DTE Electric	$242.4 million [mpsc-dte-2026]	March 5, 2026	Southeast Michigan
Consumers Energy	$276.6 million [mpsc-consumers-2026]	May 1, 2026	West, central Michigan

Both cases cited grid upgrades, reliability investment, and infrastructure modernization [mpsc-dte-2026]. The MPSC reduced the utilities' original requests but still approved substantial increases [mpsc-consumers-2026].

Unlike deregulated states where you shop supply separately from delivery, Michigan's regulated structure bundles most costs into one utility tariff for customers outside the 10% choice program.

Why choice matters for cannabis operators

Michigan limits competitive electric supply to 10% of each utility's retail load [mpsc-choice-2025]. When the cap fills, new customers join a queue. The MPSC reported the program remained fully subscribed through 2025 with 5,101 customers waiting [mpsc-choice-2025].

A cultivator who energizes a new 500 kW facility in DTE territory in 2026 likely lands on regulated rates unless choice capacity opens or they acquire an existing choice allocation through a business purchase.

SB 588, which would have lifted the 10% cap, stalled in the Michigan legislature as of early 2026 [mpsc-choice-2025]. Until law changes, regulated rate cases like these directly hit most operators.

Worked example: DTE territory indoor grow

Assume a 30,000 sq ft indoor facility in Wayne County on DTE at 400 kW peak and 480,000 kWh monthly use. Illustration only.

Before the March 2026 increase, assume an all-in bundled rate of 11.5 cents per kWh on the regulated tariff:

480,000 kWh x $0.115 = $55,200 per month

If the approved revenue increase translates to roughly 6% on this rate class (actual class impact varies by MPSC allocation):

480,000 kWh x $0.122 = $58,560 per month

That is $3,360 per month or $40,320 per year from one rate case, before Consumers-style increases if you are in their territory instead.

Demand charges within the DTE tariff add separately based on peak kW. A 400 kW peak at $12 per kW adds $4,800 per month in demand alone [mpsc-dte-2026].

DTE vs Consumers: different timing, same constraint

Operators in Kalamazoo, Grand Rapids, or Lansing fall under Consumers Energy [mpsc-consumers-2026]. The May 1 effective date means Q2 2026 bills reflect the increase. DTE customers saw changes starting March bills [mpsc-dte-2026].

Multi-site operators spanning both territories need separate bill analysis. Rate class names, demand charge levels, and approved percentage increases differ between the two utilities even though both operate under MPSC jurisdiction.

What you can still do on regulated rates

Shopping supply is not available without choice capacity, but cost management is not zero:

Strategy	Target	Available without choice?
LED retrofit + rebates	kWh and kW	Yes
Load shifting / staggered lighting	Peak kW demand	Yes
Rate class review	Tariff schedule	Yes
Queue for electric choice	Supply price	Join queue [mpsc-choice-2025]
On-site solar (where viable)	kWh offset	Yes, subject to interconnection rules

DTE Energy territory details and Consumers Energy rates cover schedule specifics. See Michigan cultivation facility energy for load benchmarks.

Joining the choice queue

If you are not yet in the queue, enrollment puts you in line when capacity opens [mpsc-choice-2025]. Choice capacity frees up when existing choice customers return to regulated service or reduce load. The queue position matters: 5,101 customers were waiting as of the 2025 status report [mpsc-choice-2025].

Some operators acquire existing facilities with active choice enrollment rather than waiting for new capacity. Confirm the choice allocation transfers with the meter on any acquisition.

Tracking future cases

Both utilities file regularly for rate adjustments. DTE's March 2026 order may not be the last request in the calendar year [mpsc-dte-2026]. Budget conservatively and monitor MPSC news releases for interim and future filings.

Consumers Energy vs DTE: different territories, same constraint

Grand Rapids, Lansing, and Kalamazoo operators on Consumers Energy saw May 1 effective dates [mpsc-consumers-2026]. Detroit metro and Ann Arbor operators on DTE saw March 5 changes [mpsc-dte-2026]. Rate schedule names, demand charge tiers, and approved percentage increases differ even when dollar amounts look similar.

Multi-site operators should not copy one facility's bill analysis to another territory without re-running the numbers on the correct tariff.

Medical vs adult-use licensing and load growth

Michigan's cannabis market includes medical provisioning centers and adult-use grows under separate license types [mpsc-dte-2026]. Expansions that add canopy or processing equipment increase peak demand and may push you into a higher rate class on the same utility. File queue enrollment before expansion if you hope to access choice when capacity opens [mpsc-choice-2025].

Efficiency rebates while on regulated rates

DTE and Consumers Energy offer commercial efficiency programs that can reduce kWh and kW even without choice access [mpsc-dte-2026]. LED horticultural retrofits with DLC-listed fixtures may qualify for prescriptive rebates. Custom incentives require pre-approval. Rebate treatment under 280E is a tax question for your advisor, not your utility account manager.

Choice cap makes rate cases more painful for locked-in growers

Michigan limits alternative supplier enrollment to ten percent of load [mpsc-choice-2025]. If your facility cannot exit utility default supply, DTE's $242.4 million and Consumers' $276.6 million increases flow straight to your bill with no shopping escape [mpsc-dte-2026] [mpsc-consumers-2026]. Efficiency and demand management become the primary levers until a queue slot opens or SB 588 advances.

Track the MPSC competition report each February for queue movement.

MISO capacity embedded in Michigan bundled rates

Customers on regulated bundled tariffs pay MISO capacity costs inside the utility rate, not as a separate line item [mpsc-dte-2026]. DTE and Consumers Energy recover capacity through MPSC-approved cost recovery mechanisms. When MISO capacity prices rise, future rate cases may seek additional revenue even after the March and May 2026 approvals [mpsc-consumers-2026].

Choice customers who eventually exit bundled service still pay capacity through their alternative energy supplier contract [mpsc-choice-faq]. The 2026 rate increases hit now. Capacity moves later through whichever path your account uses.

PowerPlant and load data reporting

Michigan cannabis facilities must comply with state energy reporting requirements separate from utility rate cases [mpsc-dte-2026]. Higher regulated rates increase the financial return on efficiency investments that also improve reported metrics. LED retrofits that cut peak demand help both the PowerPlant filing and the demand charge line on your DTE or Consumers bill [mpsc-dte-2026].

Document baseline kWh and kW before major equipment changes. Regulators and investors both ask for year-over-year comparisons when rates rise [mpsc-consumers-2026].

Queue enrollment at project inception

The MPSC reported 5,101 customers waiting for choice capacity in 2025 [mpsc-choice-2025]. New cultivation projects should file queue enrollment at financing close, not at energization [mpsc-choice-faq]. Queue position is first-in-first-out when capacity frees. A facility that waits until the meter is live adds months or years behind other commercial loads already in line [mpsc-choice-2025].

Confirm whether an acquisition target holds active choice enrollment before buying an operating facility. Transfer rules require MPSC notification when ownership changes [mpsc-choice-faq]. A purchased choice slot may be worth more than equipment if supply savings exceed six figures annually.

Rate class review after canopy expansion

Adding flower rooms or extraction equipment increases peak kW and may push a facility into a higher commercial rate tier on the same utility [mpsc-dte-2026]. DTE and Consumers Energy assign rate schedules based on peak demand and voltage level. A facility that crossed from secondary to primary voltage during expansion needs a new tariff analysis under the March or May 2026 approved rates [mpsc-consumers-2026].

Contact utility account management before energizing new load. Reclassification can apply retroactively if the utility audits interval data and finds peak demand exceeded the prior schedule threshold [mpsc-dte-2026].

The March 5 DTE effective date and May 1 Consumers effective date mean Q1 and Q2 2026 bills reflect different rate levels for multi-state operators [mpsc-dte-2026] [mpsc-consumers-2026]. Update each facility's monthly budget on the correct date rather than applying a single statewide percentage increase [mpsc-choice-2025].

Pull the MPSC order for your utility and rate class to find the approved percentage change for your schedule. Statewide revenue dollar figures do not translate directly to your bill without class allocation detail [mpsc-dte-2026].
