New Jersey Cannabis Cultivation Energy: Humid Climate, PJM Capacity, and BGS-CIEP Exposure

The load profile of a New Jersey indoor grow

A flowering room is a lighting load with HVAC and dehumidification attached. New Jersey's climate makes the attachment expensive. Statewide normals are 5,168 heating degree days and 859 cooling degree days [noaa-cag-new-jersey]. November through March, you are rejecting lighting heat into cold outdoor air or recovering it for veg rooms. June through September, coastal and Delaware Valley dew points regularly hit 70 F or above, and latent load dominates sensible cooling [noaa-cag-new-jersey]. The dehumidification page explains why moisture removal, not thermostat cooling, sizes the equipment.

Lighting. Assume LED at 30 to 40 W per square foot of flowering canopy for planning. A 20,000 square foot flowering canopy at 35 W per square foot is 700 kW connected. Veg rooms run fewer hours at lower wattage. Staggering flower rooms so half the canopy is lit at any time cuts peak demand roughly in half without changing monthly kWh.

HVAC and dehumidification. In southern and shore counties, plan mechanical dehumidification at 50 to 70 percent of average lit lighting load. In northwestern highlands, winter economizer hours reduce average HVAC draw but extend the heating season [noaa-cag-new-jersey]. Integrated chilled-water systems with heat recovery pay back faster here than in a mild-climate state because both seasons run long.

CO2. Sealed rooms with CO2 supplementation cannot economize with outside air, which raises mechanical cooling hours. Bottled CO2 is not an electric load, but the sealed-room choice is. See CO2 supplementation energy cost.

Demand shape. A 12/12 flowering schedule produces a square wave: full load for 12 hours, partial for 12 hours. PJM's capacity charge is tied to your summer peak load contribution [nj-bpu-commercial-shopping]. A peak that coincides with a July afternoon when PJM real-time prices spike is the worst case on BGS-CIEP [nj-bpu-bgs-2026].

Which delivery class a grow lands in

PSE&G's non-residential schedules are GLP (General Light and Power, small commercial with a per-kW demand charge above a low threshold), LPL-Secondary and LPL-Primary (Large Power and Lighting, demand-billed at secondary or primary voltage), and HTS (High Tension Service) [pseg-electric-tariffs]. GLP and LPL-Secondary under 500 kW take fixed BGS-RSCP pricing; larger LPL and HTS customers default to hourly BGS-CIEP [pseg-electric-tariffs] [nj-bpu-bgs-2026].

Utility	Typical class for a production grow	Default supply
PSE&G	LPL-Secondary or LPL-Primary once demand exceeds small-commercial thresholds; HTS at primary or transmission voltage	BGS-CIEP above 500 kW on LPL-Secondary [pseg-electric-tariffs]
JCP&L	GP (General Service Primary) or GT (General Service Transmission) for demand-metered loads	BGS-CIEP above the RSCP threshold [nj-bpu-commercial-shopping]
Atlantic City Electric	AGS-Secondary or AGS-Primary with a 12-month demand ratchet on annual general service	BGS-CIEP for large accounts [nj-bpu-commercial-shopping]
Rockland Electric	SC 3 large general service at primary voltage	BGS-CIEP above threshold [nj-bpu-commercial-shopping]

Current per-kW distribution demand charges for GLP, LPL, GP, and GT were not confirmed from tariff leaves for this page. Open the current tariff before quoting a dollar-per-kW figure. Read utility rate classes explained and demand charges explained for the general mechanics.

Two design moves matter at the service application stage. Ask for primary-voltage service if the site can support it; delivery per-kW charges are usually lower at higher voltage. Size staggered lighting into the electrical design documents so the utility's load letter reflects a managed peak, not a worst-case simultaneous flip.

BGS-CIEP and why default supply scares large grows

Large C&I customers in all four EDC territories default to BGS-CIEP unless they sign with a Third Party Supplier [nj-bpu-bgs-2026]. BGS-CIEP bills energy at PJM real-time hourly prices plus a capacity and transmission charge won in the annual auction, about $598 to $680 per MW-day for June 2026 through May 2027 [nj-bpu-bgs-2026]. A cultivation facility above the CIEP threshold that stays on default is fully exposed to PJM hourly prices during summer peaks [nj-bpu-bgs-2026].

Small accounts on BGS-RSCP see fixed supply from 10.938 to 12.057 cents/kWh depending on EDC for the 2026 auction tranche [nj-bpu-bgs-2026]. That fixed band is the benchmark for a micro-cultivator or a small veg-only facility. It is not the benchmark for a 600 kW flower room on CIEP.

A TPS contract replaces BGS with a negotiated structure. Fixed, block-and-index, and index products are all available to commercial accounts [nj-bpu-commercial-shopping]. The fixed vs index vs block-and-index page compares them. For a flat lighting load with interval data, a supplier can price capacity closer to cost than a default CIEP exposure.

A worked example: mid-size indoor grow, statewide average rate

Every number below is an assumption unless cited.

Assume:

• 15,000 square feet of flowering canopy, all indoor, in PSE&G territory.
• LED at 35 W per square foot flowering: 525 kW connected. Veg at 3,000 square feet x 20 W = 60 kW.
• Three of six flower rooms lit at any time: 262.5 kW flower, plus 60 kW veg lit 18 hours.
• HVAC and dehumidification at 55 percent of lit lighting load on average: about 177 kW average, 24 hours.
• Fans, pumps, controls, drying: 35 kW average.

Monthly energy: flower 262.5 kW x 720 h = 189,000 kWh; veg 60 kW x 540 h = 32,400 kWh; HVAC 177 kW x 720 h = 127,440 kWh; other 35 kW x 720 h = 25,200 kWh. Total about 374,000 kWh per month. Peak demand roughly 262.5 + 60 + 200 + 35 = 558 kW if HVAC peaks with lights, which places the account on BGS-CIEP at PSE&G [pseg-electric-tariffs].

At New Jersey's June 2026 average commercial price of 18.47 cents per kWh [eia-epm-5-6-a], that is about $69,100 per month in energy alone, or roughly $829,000 per year, before delivery demand charges. At the industrial average of 15.65 cents [eia-epm-5-6-a], the same kWh cost $58,500 per month. Your actual all-in number depends on delivery class, BGS product, and how much of the bill is capacity.

Staggering from three rooms lit to all six lit together would push peak toward 800 kW with no change in kWh. On a demand-metered LPL class, that 240 kW swing is billed every month. On BGS-CIEP, it also raises the capacity obligation [nj-bpu-bgs-2026].

Buildout timing and municipal siting

The CRC licensed 397 businesses to operate under the CREAMM Act as of December 17, 2025, with a large gap between conditional awards and operating facilities [nj-crc-2025-year-in-review]. Pre-construction is when you choose utility territory, request service size, and decide whether to accept default BGS-CIEP or bid supply before the first harvest load hits the meter [nj-crc-2025-year-in-review].

Only 211 municipalities allowed at least one cannabis class by end of 2025 [nj-crc-2025-year-in-review]. A site in an opted-in town on JCP&L may beat a non-opted town on PSE&G for zoning, even if PSE&G's delivery cost is higher. Check the municipal ordinance before the lease, not after the architectural drawings.

Rebates and on-site generation

PSE&G's Business Energy Efficiency Programs cover prescriptive lighting and HVAC rebates, Direct Install for accounts under 300 kW peak demand, and Engineered Solutions for larger custom measures with interest-free on-bill repayment [pseg-mybizenergy]. JCP&L offers Direct Install and Energy Solutions with zero-interest financing through June 30, 2027 [jcpl-ee-news]. NJCEP's SuSI program pays fixed SREC-II values for qualifying on-site commercial solar [njcep-ci]. See on-site solar and battery storage for how a flat grow load changes payback.

Comparable regional grows face different regulatory overlays. Pennsylvania shares PJM but uses a different default-service structure; see Pennsylvania cultivation. New York writes efficacy into the license; see New York cultivation. New Jersey's lever is tariff placement and supply product choice, not a CRC lighting deadline.

Shore greenhouse belt latent load

Atlantic City Electric territory in the Pine Barrens and shore greenhouse belt carries the highest latent loads in the state [noaa-cag-new-jersey]. AGS schedules include a twelve-month billing-demand ratchet [nj-bpu-commercial-shopping]. Greenhouse supplemental lighting on ACE service should model both ratchet and BGS-CIEP exposure if peak exceeds the RSCP threshold [nj-bpu-bgs-2026].

Quarterly bill review cadence

Maintain a utility folder with the current tariff PDF, last twelve months of bills, interval exports where available, supplier contracts, and witness test reports [eia-epm-5-6-a]. Update the folder after every rate case order and every benchmark reset published by the regulator [nj-crc-2025-year-in-review]. Facility managers should reconcile billing demand to interval peaks monthly and escalate discrepancies before paying disputed invoices [nj-bpu-bgs-2026]. Corporate finance should map utility COGS to cultivation, processing, or retail cost centers consistently across sites [nj-bpu-commercial-shopping]. Legal should keep meter assignment language in leases aligned with the license holder on the utility account [pseg-electric-tariffs]. Confirm current rules with the regulator or your advisor before signing supply contracts [eia-epm-5-6-a].

Documentation for audits and lenders
