Cannabis energy questions, answered plainly

If your state has retail electric choice and your account is on an eligible utility tariff, yes. Pennsylvania's PUC FAQ states that most residents can choose an electric generation supplier, and the same choice program covers commercial customers in investor-owned utility territories. Illinois allows all non-residential ComEd and Ameren customers to buy supply from an Alternative Retail Electric Supplier certified by the ICC. The cannabis license type does not appear in either state's eligibility rules. What matters is your utility territory, rate class, and whether competitive offers exist for your load size.

Some have. The Vermont Law Farm and Energy Initiative report describes cultivators facing limited supplier options and notes that some retail suppliers have been unwilling to serve cannabis accounts, leaving growers on utility default supply. That is supplier risk management, not a state ban. Large cultivation loads with high kWh and high peak kW are actually attractive to suppliers in competitive markets if the credit check clears. A broker or direct outreach to several licensed suppliers usually surfaces who will quote cannabis. Always get the offer in writing before you assume refusal.

There is no single standard fee. Small commercial contracts sometimes use a flat dollar amount or a fee per remaining month. Larger cultivation accounts usually face a market-based formula: the difference between your contract price and the current market price for the remaining term, multiplied by expected remaining volume, plus an administrative charge. If market prices rose after you signed, the fee can be zero. If prices fell, the fee can be six figures. Read the exact formula and whether it uses hourly or monthly settlement prices.

Bandwidth, also called swing or tolerance, is the percentage band around your expected monthly usage inside which the fixed price applies. Usage above the band is priced at market or a penalty rate; usage below may be sold back at market. A plus or minus ten percent band is common; full requirements contracts with zero tolerance cost more per kWh because the supplier carries all volume risk. Closing a flower room that drops load forty percent triggers bandwidth language unless you renegotiate or prove force majeure.

A demand charge is a fee based on your highest average power in kilowatts during a fixed interval within the billing period, usually 15 or 30 minutes, not on total kilowatt-hours. NREL's survey of utility tariffs describes billing demand as the peak kW in those windows. Santee Cooper bills on the maximum 30-minute demand in the period. The utility sizes wires and transformers for that peak whether it lasts one interval or all month, so the charge allocates infrastructure cost to customers who create spikes.

Because lighting and HVAC stack on the same interval. NREL found demand can account for 30 to 70 percent of a commercial customer's bill depending on tariff. The Northwest Power and Conservation Council survey found lighting was 66 percent of electricity use at licensed indoor producers, with flowering rooms alone at 49 percent. Hundreds of kilowatts of lights switch on together and compressors follow. Two facilities with the same monthly kWh can pay very different demand charges if one's load is flat and one's peaks sharply.

Most commercial brokers are paid by the retail electricity supplier, not by you directly. The supplier adds the broker's fee to the per-kWh price in the contract. The fee is usually quoted in mils, thousandths of a dollar per kWh. Pennsylvania's PUC defines a broker as a licensed firm that acts as an agent in the sale and purchase of electricity but never owns the electricity itself. Because the broker does not own power, the commission is built into the rate you sign, not billed separately on most deals.

Yes, on the typical supplier-paid model. If a supplier quotes 7.4 cents per kWh and the broker fee is 3 mils, the supplier's own energy price was 7.1 cents and 0.3 cents is the broker's. You pay one supply rate on the bill or contract. Illinois requires licensed agents, brokers, and consultants to disclose the total price per kWh inclusive of all fees or commissions before you sign. Texas requires brokers to describe how they will be compensated and by whom before starting service.

It depends on your tolerance for a bad month, not on a market prediction. After PJM's 2026/2027 capacity auction cleared at the price cap of 120,147 dollars per MW-year, suppliers are baking high capacity costs into fixed quotes for delivery years starting June 1. Floating on index can average lower over time, but a cultivation facility with lights on twelve hours a day cannot absorb a spike the way a warehouse with a daytime shift can. Most operators fix a base block and leave the edges floating, or fix twelve to twenty-four months and re-shop before renewal.

Index and variable mean the same thing in most supplier contracts: your price moves with a published wholesale index, usually the ISO's locational marginal price plus an adder. The Pennsylvania PUC defines a variable price as an all-inclusive per kWh price that can change by the hour, day, or month according to the supplier's disclosure statement. Block-and-index fixes a stated quantity of megawatts for stated hours at a fixed price and settles everything above or below that block at the index. A flat grow load is a good fit for a block sized to your base.

Compare dollars, not ideology. Pull twelve months of bills. If delivery demand is more than thirty percent of spend and peak kW jumped when rooms were synchronized, stagger schedules and rate-class review come before capex. If demand is modest but default supply reset upward in a PJM or ISO-NE state, a fixed supplier contract may save more this year than a partial LED swap. LED still wins on a five-year horizon when you are on HPS and rebates exist, because it cuts kWh and heat load. Run both numbers with your actual tariff before you prioritize.

Often yes, because demand charges use the highest average kW in a billing interval, not total kWh. When every flower room flips on at 6 a.m., lighting and HVAC stack into one spike. Offsetting two rooms by two hours can drop peak kW while daily kWh stays nearly flat. The Northwest Council survey found HVAC and lighting drive most cultivation load, and Cannabis Business Times lists staggered scheduling among practical demand strategies. Verify against your interval data: if peaks already happen at different times, staggering helps less.

Often one cycle, aligned to your meter read. Connecticut's Energize CT FAQs state that if you are switching suppliers and enroll at least ten days before your next meter read date, the switch happens on that read date, which is printed on your bill. If you miss the window, you wait for the following cycle. Other states follow similar read-date mechanics even when the statute does not quote an exact day count. Plan enrollment around the read date, not the day you sign.

Texas can be faster because ERCOT administers retail switching electronically for competitive areas. Pennsylvania's PUC FAQ states that under accelerated switching rules most customers can be switched in three business days once the utility is notified by the supplier. Connecticut ties the switch to the next meter read if you enroll ten days ahead. Illinois says no one visits your site and there is no service disruption, but the effective date still follows utility enrollment processing. Texas is often measured in days; Northeast and Mid-Atlantic switches are often measured in read cycles.

Divide annual intensity by 365. The Northwest Power and Conservation Council measured indoor-only operations at about 128 kWh per square foot of canopy per year, which is roughly 0.35 kWh per square foot per day on average. That is an annual average, not a constant draw. Lights-on hours push the instantaneous rate much higher, and veg rooms run different schedules than flower. Greenhouse canopy in the same survey averaged 12 kWh per square foot per year, about 0.03 kWh per square foot per day. Always confirm whether the benchmark uses canopy or gross floor area before you compare your meter to it.

Published ranges for indoor cultivation run from about 2,000 to 5,000 kWh per pound of finished product, depending on facility efficiency and how much veg and drying share the same meter. A MJBizDaily industry column in 2025 cited that band for indoor grows. Southern California Edison's 2021 market characterization used about 1,200 kWh per pound in one worked example for a 5,000 square foot facility harvesting three cycles a year. Your number depends on yield, strain, and whether you count only flower rooms or the whole building. Track kWh divided by dry pounds harvested for a number you can defend.

In most choice states, yes. Illinois requires Agents, Brokers and Consultants to hold an ICC certificate under Section 16-115C and 83 Ill. Adm. Code Part 454. Texas registers brokers under 16 TAC 25.112. Pennsylvania licenses brokers as part of its electric generation supplier framework. Maryland defines brokers in COMAR 20.51 and requires a bond for broker applicants. The licensing agency is always the state public utility commission or equivalent, not the cannabis regulator. If your state has choice, check the PUC website for an ABC, broker, or aggregator registry before you hire anyone.

State-licensed cannabis operators are legal businesses under state law, and electricity supply is a state-regulated service. PUC broker licenses do not exclude cannabis NAICS codes. Federal controlled-substance status affects banking, taxes, and some incentive programs, but it does not make a retail supply contract void on its face. Suppliers and brokers still run credit checks and may decline cannabis accounts individually. That is commercial risk screening, not a statute banning the relationship. Confirm contract enforceability with your attorney if you are concerned about a long fixed term.

For the same light on the canopy, expect roughly 30 to 45 percent less lighting electricity when you move from double-ended HPS to a current DLC-listed LED. Hort V4.0 sets the minimum photosynthetic photon efficacy at 2.5 micromoles per joule, which the DLC states is more than 45 percent above the most efficacious 1000 W double-ended HPS option. Resource Innovation Institute benchmarking shows LED facilities using less energy per square foot than HPS facilities in comparable categories. Savings on the bill also depend on how much HVAC and dehumidification load drops with the waste heat.

Many investor-owned utilities in deregulated and regulated states run commercial efficiency programs that cover horticultural lighting, but the list changes by territory and budget year. ComEd, Eversource, National Grid, PSEG, and several Pennsylvania utilities have offered prescriptive or custom incentives for DLC-qualified fixtures. Programs require pre-approval in most cases and cap funding annually. Check your utility's business efficiency portal and DSIRE for the current measure list. A rebate in one town does not guarantee the same rebate in the next town if the utility differs.

At schematic design, not at final inspection. Cultivation loads are large enough that service size, transformer location, and line extension routes affect site layout and civil budget. Submit a load letter with peak demand, load factor, and phased energization plan as soon as you have a single-line diagram. Utilities queue large commercial requests separately from small tenant improvements. Twelve to eighteen months lead time is common for greenfield service above one MW, though it varies by territory. Parallel path supply procurement while the utility engineers service.

Size to coincident peak kW, not nameplate fixture watts. Indoor flower rooms with HID or LED lighting, dehumidification, and HVAC often land between 40 and 80 watts per square foot of canopy at peak depending on design. A 20,000 sq ft flowering canopy might present 800 kW to 1.2 MW of connected load with diversity, and the utility will size transformers and fees to your expected peak. The Northwest Power and Conservation Council survey shows wide variation by facility type and vintage. Your mechanical engineer's peak calculation is the starting point for the service application.

Partially, not completely, for most indoor facilities. Solar.com notes that producing a pound of marijuana can take about 2,000 kWh under warehouse conditions, and a 500-light operation might need on the order of 1.5 MW of solar to match load, which exceeds typical roof space. Rooftop arrays often cover 10 to 20 percent of annual kWh for an indoor grow. Solar still helps with daytime load, demand shaving paired with batteries, and compliance documentation in states that reward renewable generation. Greenhouse and mixed-light operations can reach much higher self-supply fractions.

Generally no for plant-touching cultivators and processors while marijuana remains federally controlled. Solar.com states that growers cannot take advantage of the federal investment tax credit because the federal government does not legally recognize cannabis cultivation. Medical operators with FDA-approved products may face a different analysis after recent rescheduling moves, but confirm with a cannabis tax advisor before modeling a credit. Without the ITC, on-site solar payback depends on avoided kWh and demand, not on a 30 percent tax offset.

Yes. Pennsylvania's PUC shopping FAQ states that your electric distribution company remains the same when you choose a new supplier, and you still call the utility about outages and repairs. Connecticut's Energize CT FAQs say only Eversource or UI can shut off service, not a supplier. Plug In Illinois tells customers to keep calling ComEd or Ameren for outages regardless of who supplies energy. The supplier sells generation; the utility runs the wires.

Usually one. Pennsylvania's FAQ says most customers receive a single monthly bill from the electric utility with the supplier's generation charges included. Some suppliers request direct billing, in which case you receive one bill from the utility for delivery and one from the supplier for generation. Connecticut notes the same split: consolidated billing is standard, direct billing is optional. Ask before you enroll which model your supplier uses.

Federal survey data is the honest benchmark because there is no cannabis-specific retail energy census. EIA's 2018 Commercial Buildings Energy Consumption Survey shows non-mall retail buildings averaging 13.7 kWh per square foot per year, with a median of 9.0. A 3,000 square foot store near the average uses about 41,000 kWh per year, or roughly 3,400 kWh per month. Heavy display refrigeration, 12-hour retail days, and a large camera count push toward the upper end. Track your own meter for twelve months before you budget from a rule of thumb.

Regulated cannabis retail adds loads ordinary stores skip or run lighter. State rules commonly require 24-hour video recording with retention and backup power. Massachusetts requires cameras enabled to record 24 hours each day with recordings kept at least 90 days and outage backup of at least four hours. Product refrigeration for edibles and beverages runs continuously. Vault HVAC, seed-to-sale servers, and bright display lighting add kWh. The gap is often 10 to 30 percent above a generic retail benchmark, not double, unless the store runs extreme refrigeration or was misclassified on the utility account.

Yes, for supply. Customers in ComEd and Ameren Illinois territories can choose an alternative retail electric supplier for the generation portion of the bill while the utility continues delivery, outage response, and metering. Plug In Illinois states that switching does not disrupt service and that delivery charges stay the same whether or not you switch. Cannabis license type is not a barrier in the choice rules themselves, though individual suppliers set their own credit policies.

Yes. Pennsylvania's PAPowerSwitch site is the official shopping portal for the PUC, and most Pennsylvania customers can choose an electric generation supplier. Ohio runs Energy Choice Ohio for competitive retail electric service. Maryland's PSC operates an electric choice program where licensed suppliers compete on supply while the utility delivers. In all three, a state-licensed cannabis facility is a commercial customer like any other for choice purposes.
