New York OCM Energy Use Plan: Metering, Efficiency, and No Fossil Primary
New York cannabis regulations require cultivators to maintain energy use plans with metered data, efficient horticultural lighting and HVAC, and no fossil-fuel combustion as primary energy. Plans align with PowerScore reporting and CLCPA climate goals. Metering granularity affects both OCM compliance and your ability to negotiate supply contracts with accurate load data.

Updated September 11, 2026OCM's energy use framework
New York legalized adult-use cannabis through MRTA with explicit climate intent [ny-ocm-sustainability]. OCM regulations require medical and adult-use licensees to maintain energy use plans, manage emissions, and track resources through PowerScore [ny-ocm-sustainability] [ny-energy-use-plan-pdf].
Energy rules include [ny-ocm-sustainability]:
Installation of energy meters.
Efficiency standards for horticultural lighting.
HVAC and dehumidification equipment standards including refrigerant limits.
Prohibition on fossil fuel combustion as primary energy.
Rules align with the Climate Leadership and Community Protection Act [ny-clcpa].
Energy Use Plan vs PowerScore
| Document | Purpose |
|---|---|
| Energy Use Plan | Forward-looking compliance: equipment specs, primary energy sources, efficiency measures |
| PowerScore | Backward-looking reporting: actual kWh, water, waste, production |
Plans should match installed equipment when you file PowerScore. Retrofits in 2025 or 2026 require plan updates before next reporting cycle [ny-energy-use-plan-pdf].
Metering requirements in practice
OCM expects meters that support accurate annual reporting [ny-ocm-sustainability]. At minimum:
Utility master meter kWh and peak demand for PowerScore monthly fields.
Ability to reconcile on-site solar or storage if present.
Documentation for alternative fuels if used for backup only.
Facilities with multiple rooms benefit from submetering even when not explicitly mandated per room. Submeters help prove lighting and HVAC efficiency measures work and isolate vege vs flower load for scheduling.
Interval data from AMI meters also supports supplier negotiations in New York electric choice.
Horticultural lighting efficiency
Regulations target efficient horticultural lighting consistent with industry DLC direction [ny-ocm-sustainability]. Practically:
Specify DLC Hort QPL fixtures in buildouts.
Document controls (scheduling, dimming where used).
Retire HPS that fails efficacy benchmarks unless grandfathered under specific license tiers (confirm current Part 123/124 text with OCM).
Lighting choices drive HVAC sizing and dehumidification load. Energy Use Plans should show coordinated engineering, not lighting-only swaps.
HVAC, dehumidification, and refrigerants
OCM highlights refrigerant GWP limits for HVAC and dehumidification [ny-ocm-sustainability]. Equipment selections must appear in plans with engineer sign-off where required.
Oversized DX units inflate both kWh and peak kW. Undersized units fail humidity targets. Plans should reference design conditions for New York climate zones (humid summers, cold winters).
No fossil fuel as primary energy
Prohibition on fossil fuel combustion as primary energy pushes cultivators toward grid electricity, renewable grid supply contracts, or electric heat pumps [ny-ocm-sustainability].
Interpret carefully:
Primary vs backup generators.
Natural gas for CO2 enrichment (separate from space heat in some designs).
Propane forklifts vs building heat.
Document backup fuel use as emergency-only in plans [ny-energy-use-plan-pdf]. Confirm with OCM if dual-fuel systems are proposed.
Grid supply can be renewable via retail green products or RECs; see renewable energy certificates.
Fossil-free primary energy and supply contracts
Choosing a 100% renewable supply contract does not by itself satisfy equipment and metering rules, but it supports CLCPA alignment in plans [ny-clcpa].
When shopping suppliers, verify:
Renewable claims (Green-e, REC retirement).
Fixed vs index price.
NYISO ICAP pass-through for downstate sites.
Contract length vs license tenure.
Small cultivator equity provisions
OCM allows smaller-scale licensees two licensing periods to meet some standards [ny-ocm-sustainability]. Equity tier operators should still install metering early to establish baselines.
Delaying meters makes PowerScore filings harder and hides bad kWh per pound trends.
Electric primary energy in cold-climate design
The no fossil fuel as primary energy rule pushes New York buildouts toward grid electricity and heat pumps for space conditioning [ny-ocm-sustainability]. In Climate Zone 6 grow rooms, a 400 kW lighting load still dominates bills, but winter make-up air can spike therms if someone slips a gas unit heater past plan review [ny-energy-use-plan-pdf].
Energy Use Plans should show:
Primary heat source (electric boiler, VRF, or hydronic heat pump).
Backup generator fuel typed as emergency-only with annual test-hour caps documented [ny-energy-use-plan-pdf].
Dehumidification strategy sized for latent load from transpiration, not generic office HVAC [ny-ocm-sustainability].
A 30,000 sq ft hybrid veg/flower facility might specify 1,200 kW connected lighting, 250 kW HVAC, and zero therms for space heat while still listing CO2 enrichment sources separately if regulations distinguish process gas from building heat [ny-energy-use-plan-pdf]. Misclassification triggers plan rejection before PowerScore ever opens [ny-ocm-sustainability].
Plan amendments after a 2025 LED retrofit
If you swapped 600 legacy HPS fixtures for DLC Hort QPL LEDs in 2025, your forward-looking Energy Use Plan must match installed wattage before the August 31 PowerScore cycle [ny-energy-use-plan-pdf]. File an amendment describing:
Removed connected kW and expected kWh reduction.
Updated single-line electrical diagram.
Refrigerant types on any resized rooftop units [ny-ocm-sustainability].
Submeter data from veg and flower rooms helps prove the retrofit hit forecast savings when OCM compares plan to reported kWh [ny-ocm-sustainability]. Without amendment, you risk inconsistency between plan specs and PowerScore equipment fields [ny-energy-use-plan-pdf].
Checklist for new buildouts
Engineer stamps lighting and HVAC specs before occupancy.
Install master and critical branch metering before first harvest.
File Energy Use Plan updates when equipment changes.
Map no fossil primary design in architectural submissions.
Schedule acceptance tests aligned with local building code.
Enter first PowerScore data within required deadline [ny-ocm-sustainability].
Checklist for operating facilities
Audit 2025-26 bills against plan assumptions.
Update plan if LED retrofit changed load profile.
Verify refrigerant types on existing chillers.
Confirm generators labeled emergency-only.
Reconcile peak kW growth with room expansions.
Interaction with NYC capacity costs
Downstate Energy Use Plans do not reduce Zone J ICAP pass-through. Efficiency lowers kWh; peak kW management lowers both delivery and ICAP obligation where peak drives assignment.
Plan metering to identify scheduling improvements before next summer capability period.
Confirm with OCM
Regulations evolve. Download current PDFs from cannabis.ny.gov/sustainability before permit submissions [ny-energy-use-plan-pdf].
This page summarizes publicly posted OCM themes; it is not legal advice. Submit questions to info@ocm.ny.gov for binding guidance [ny-ocm-sustainability].
Sample Energy Use Plan table for a 20,000 sq ft hybrid facility
Forward-looking plans must match equipment on the floor when PowerScore filings go in [ny-energy-use-plan-pdf]. Illustrative rows for an adult-use site in Climate Zone 6:
| System | Plan specification | Compliance hook |
|---|---|---|
| Flower lighting | DLC Hort QPL LED, 32 W/sq ft design | Efficiency standard [ny-ocm-sustainability] |
| Veg lighting | Separate schedule, 28 W/sq ft | Metered branch if submetered [ny-energy-use-plan-pdf] |
| Primary heat | Electric hydronic, no gas unit heaters | No fossil primary rule [ny-ocm-sustainability] |
| Dehumidification | Low-GWP refrigerant, PE-sized coils | Refrigerant limits [ny-ocm-sustainability] |
| Backup power | Diesel generator, emergency-only tests | Documented test hours [ny-energy-use-plan-pdf] |
| On-site solar | 400 kW rooftop, no fossil primary claim | CLCPA alignment [ny-clcpa] |
CO2 enrichment from bottled or recovered CO2 should be described separately from space heat if your engineer distinguishes process gas in the plan narrative [ny-energy-use-plan-pdf]. Misclassification triggers plan rejection before cultivation starts [ny-ocm-sustainability].
After a 2025 LED retrofit, file an amendment with removed connected kW, updated one-line diagram, and resized rooftop units if HVAC changed [ny-energy-use-plan-pdf]. Submeter data proving kWh drop supports both plan accuracy and future supply RFPs on New York electric choice [ny-ocm-sustainability].
Equity tier timing and metering baselines
OCM allows smaller-scale licensees two licensing periods to meet some standards [ny-ocm-sustainability]. Equity operators sometimes delay metering to avoid upfront cost [ny-energy-use-plan-pdf]. That delay backfires: without twelve months of baseline data, you cannot prove efficiency gains in PowerScore or negotiate supply contracts with credible load shapes [ny-ocm-sustainability] [ny-clcpa].
Install master metering at certificate of occupancy, even if full DLC Hort QPL lighting arrives in phase two [ny-energy-use-plan-pdf]. Early baseline months with temporary construction loads should be flagged in internal notes so they are not compared to steady-state production years [ny-ocm-sustainability].
Refrigerant GWP limits on HVAC and dehumidification equipment appear alongside lighting rules in OCM's sustainability overview [ny-ocm-sustainability]. Selecting low-GWP chillers during buildout avoids plan amendments later when equipment is already on the roof [ny-energy-use-plan-pdf].
CLCPA alignment without conflating supply and compliance
The Climate Leadership and Community Protection Act sets statewide decarbonization goals [ny-clcpa]. A 100% renewable retail supply contract supports CLCPA narrative in your Energy Use Plan but does not replace metering, efficient fixtures, or the no-fossil-primary equipment rule [ny-ocm-sustainability] [ny-energy-use-plan-pdf]. Verify Green-e or REC retirement claims with your supplier in writing [ny-clcpa].
Choosing green supply also does not reduce Zone J ICAP pass-through for downstate sites [ny-ocm-sustainability]. Plan metering to separate compliance data from supplier settlement: PowerScore kWh, Con Edison delivery kW, and NYISO capacity assignment follow different rules [ny-energy-use-plan-pdf]. Interval data from AMI meters supports both OCM reporting and New York electric choice negotiations when load shape is documented [ny-clcpa].
Oversized DX units inflate both kWh and peak kW; undersized units fail humidity targets [ny-ocm-sustainability]. Energy Use Plans should reference design conditions for New York climate zones: humid summers and cold winters both drive load [ny-energy-use-plan-pdf] [ny-clcpa].
Document backup fuel use as emergency-only in plans and confirm with OCM if dual-fuel systems are proposed [ny-energy-use-plan-pdf]. Grid supply can include renewable retail products or RECs, but that does not replace equipment standards in the plan [ny-clcpa] [ny-ocm-sustainability]. Plans should match installed equipment when you file PowerScore; retrofits in 2025 or 2026 require plan updates before the next reporting cycle [ny-energy-use-plan-pdf] [ny-ocm-sustainability].
Frequently asked questions
