California Cannabis Energy: Direct Access, CCAs, and the Highest Commercial Rates in the Lower 48

How California's cannabis market is licensed

California has run a licensed medicinal market since Proposition 215 in 1996 and a licensed adult-use market since Proposition 64, with retail sales starting January 1, 2018 [dcc-supplemental-report-fy24-25]. Both are regulated by the Department of Cannabis Control (DCC) under the Medicinal and Adult-Use Cannabis Regulation and Safety Act. DCC issues licenses by activity: cultivation (with tiers by canopy size and lighting type, from specialty cottage up to large), manufacturing, distribution, testing, retail (storefront and delivery), microbusiness, and event organizer. Local approval comes first; a city or county can ban or limit any activity, which is why the map of where facilities sit is patchy.

Two numbers matter for anyone sizing the market. DCC's FY2024-25 supplemental budget report counted 7,912 active annual licenses and 376 remaining provisional licenses at the end of its reporting period, with annual licenses up 30.7% year over year [dcc-supplemental-report-fy24-25]. And provisional licensing is over: Business and Professions Code section 26050.2 was repealed effective January 1, 2026, so every operator now needs an annual license with CEQA compliance in hand [dcc-supplemental-report-fy24-25]. DCC's report gives totals by jurisdiction rather than by license type, so we do not publish per-type counts here; the DCC license search tool is the place for a current breakdown.

For energy planning the license type matters because it predicts the load. Cultivation licenses are split into outdoor, mixed-light (two tiers by lighting wattage), and indoor. Indoor and mixed-light tier 2 grows carry the lighting and HVAC loads that drive demand charges; outdoor grows in the Emerald Triangle are often pumping and processing loads only.

How electricity choice works here (and why it is rationed)

California restructured its market in 1996 and opened Direct Access (DA) in 1998, letting any customer buy generation from a competitive Electric Service Provider (ESP) while the utility kept delivering [cpuc-direct-access]. The 2000-2001 energy crisis ended that. The CPUC suspended DA on September 20, 2001 under D.01-09-060, and residential DA has never reopened [cpuc-direct-access].

What exists today is a limited, non-residential reopening. SB 695 (2009) let the CPUC reopen DA to business customers up to each utility's historical maximum, roughly 24,800 GWh statewide, and SB 237 (2018) added 4,000 GWh for a total near 28,800 GWh [cpuc-direct-access]. That is the cap. The CPUC took a further look at expansion in D.21-06-033 and declined to raise it, so the cap is fixed unless the legislature acts [cpuc-direct-access].

Because demand for DA exceeds the cap, access is by lottery. A business files a Six-Month Notice to Transfer with its utility during the second full business week of June; for the 2027 service year that window was June 8 to June 12, 2026 [pge-direct-access]. The utility runs a randomizer, offers any headroom under its cap to the winners in order, and puts everyone else on a waitlist that expires at the end of December and must be refiled the next June [pge-direct-access]. The 2023 lottery shows how uneven the odds are: SCE had 1,206 GWh open and cleared its waitlist, PG&E had 185 GWh open and ended the year with 836 customers and 3,023 GWh still waiting, and SDG&E had 45 GWh open with 194 customers waiting [cpuc-da-lottery-2023]. If your grow is in PG&E or SDG&E territory, treat DA as a multi-year bet rather than a procurement plan.

The other non-utility supply path is Community Choice Aggregation. A CCA is a city, county, or joint powers agency that buys generation for every customer in its jurisdiction; the utility still delivers, meters, and bills [cpuc-cca-faq]. Enrollment is automatic and opt-out, with two notices in the 60 days before service starts; opting out after the first 60 days can carry conditions, and a customer who leaves must wait a year to rejoin [cpuc-cca-faq]. PG&E lists twelve CCAs in its territory, SCE lists twelve, and SDG&E's two CCAs serve more than 80% of its customers [pge-cca] [sce-cca] [sdge-cca]. For most cannabis facilities, the practical choice is CCA versus bundled utility service, with DA as a lottery ticket on top.

Whichever path you take, departed load still pays the utility's non-bypassable charges, including the Power Charge Indifference Adjustment (PCIA). The PCIA recovers the above-market cost of generation the utility contracted before you left, is set by "vintage" (the year you departed), and is re-forecast every October in each utility's ERRA filing [cpuc-pcia]. A DA or CCA rate that looks cheaper than the utility's generation rate must be compared after adding the PCIA, not before.

The whole state sits in one grid operator, CAISO, with PG&E, SCE, and SDG&E as participating transmission owners. There is no second ISO to juggle, which simplifies multi-site procurement compared with states split between PJM and MISO.

The step-by-step procedure, forms, and deadlines are in the California switching guide.

What commercial power costs here versus the rest of the country

EIA's June 2026 table puts California's average commercial price at 27.33 cents per kWh and its industrial price at 20.74, against a U.S. commercial average of 14.19 [eia-epm-5-6-a]. Only Hawaii and a few Northeast states come close. The gap is not mainly generation; it is delivery, wildfire mitigation, and public-purpose programs layered onto the distribution bill, plus the PCIA on any load that has left bundled service.

The rate page breaks down the delivery classes and demand-charge structures utility by utility: California commercial electricity rates.

The three investor-owned utilities and where cannabis sits in each

Utility	Territory	Cannabis footprint	DA position after 2023 lottery
PG&E	Northern and central California, Oregon border to Bakersfield, including the Bay Area, Sacramento Valley, and Humboldt, Mendocino, and Trinity counties	Most of the state's outdoor and mixed-light acreage	185 GWh open, 836 customers still waiting [cpuc-da-lottery-2023]
Southern California Edison	Central, coastal, and southern California outside Los Angeles city and San Diego: Inland Empire, Orange County, Ventura, Santa Barbara, Kern, Coachella Valley	Large indoor and greenhouse clusters in the Inland Empire and desert cities	1,206 GWh open, waitlist cleared [cpuc-da-lottery-2023]
SDG&E	San Diego County and southern Orange County	Retail-heavy, with indoor grows in industrial parks	45 GWh open, 194 customers waiting [cpuc-da-lottery-2023]

Municipal utilities (LADWP, SMUD, and others) are outside DA and CCA entirely; a facility inside Los Angeles city limits has one supply option, its muni.

Climate and what it does to a grow's load

NOAA's 1991-2020 normals give California 929 cooling degree days and 2,814 heating degree days per year statewide, but the average hides three climates [noaa-cag-california]. The Central Valley and Inland Empire have long, dry cooling seasons where sensible cooling drives the summer bill. Coastal and North Coast counties run humid year-round under the marine layer, so greenhouse and mixed-light grows there fight dehumidification more than heat. Mountain sites see real heating loads. The facility pages work through each load profile: cultivation, extraction, dispensary.

Incentives worth knowing

• PG&E's Agriculture Energy Savings Action Plan pays per-fixture rebates of roughly $9 to $70 for DLC Horticultural QPL LED fixtures at 3.24 umol/J or better, for retrofits and new construction, with cannabis named as an eligible crop; funds are limited and require pre-approval and field verification [pge-aesap-grow-lighting].
• SCE's Agriculture Energy Efficiency program pays per-fixture rebates on DLC-listed horticultural LEDs at 2.86 umol/J or better, with separate tiers for greenhouse, non-stacked, and stacked indoor cannabis; rates were cut 25% for projects not pre-approved or completed by August 31, 2025 [sce-agee]. We verified this only through an implementer summary, so confirm current tiers with SCE before budgeting.
• Both utilities run broader business efficiency programs (VFDs, insulation, HVAC) that a grow can stack with the lighting rebates. See LED versus HPS for the retrofit math.

California-specific quirks

Title 24 regulates grow lighting and dehumidification. Since the 2022 Energy Code took effect on January 1, 2023, controlled environment horticulture spaces with more than 40 kW of connected horticultural lighting must use fixtures rated at least 1.9 umol/J indoors (1.7 in greenhouses), install time-switch and multilevel controls, meter the aggregate lighting load, and meet dehumidification efficiency or heat-recovery standards; the 2025 code carries these forward for permits filed on or after January 1, 2026 [title24-ceh]. No other cannabis state writes grow-light efficacy into its building code.

Agricultural rates may or may not apply. PG&E and SCE both have agricultural schedules, and growing crops for sale is an agricultural end use, but processing is not, and eligibility depends on 70% of the meter's use qualifying. Whether a given indoor facility qualifies is decided meter by meter; see the utility pages.

The muni line matters. A dispensary two blocks inside Los Angeles is on LADWP with no CCA and no DA; two blocks outside it is on SCE with Clean Power Alliance as its default supplier. Check the address before you assume anything about choice.
