Pennsylvania Cannabis Energy: Electricity Choice, Rates, and Utilities for Licensed Operators

How the Pennsylvania cannabis market is built

Pennsylvania runs a medical-only program under the Medical Marijuana Act, Act 16 of 2016, with product sales beginning in early 2018 [pa-doh-growers-processors]. The Pennsylvania Department of Health, Office of Medical Marijuana, regulates both grower/processors and dispensaries [pa-doh-growers-processors] [pa-doh-dispensaries].

The supply side is small in license count but concentrated in load. Act 16 caps the program at 25 grower/processor permits, with no more than five of those also holding a dispensary permit, and an initial 50 dispensary permits each allowing up to three locations [pa-doh-growers-processors]. Pennsylvania grower/processors are vertically combined cultivation plus processing under one permit, so the cultivator and processor counts are the same population [pa-doh-growers-processors]. The Department of Health publishes lists of approved grower/processors and operational dispensaries as downloadable files rather than a headline count, so no verified current totals of active permits or open locations are stated here [pa-doh-growers-processors].

Two features of this market shape energy buying:

• Grower/processor permits are capped and combined. A single permit holder may run sealed indoor flowering rooms, extraction, and packaging under one roof, which produces one large meter with a lighting-dominated load profile rather than separate cultivation and processing accounts.
• Dispensary permits allow up to three locations each, spread across PECO's southeastern territory, PPL's central and eastern counties, Duquesne Light's Pittsburgh footprint, and the four FirstEnergy legacy districts that cover roughly two-thirds of the state's land area [pa-papowerswitch]. Retail load is small per store but adds up across a multi-location permit holder.

Adult-use legalization remains stalled, not dead. HB 1200 passed the House 102-101 in May 2025 and was tabled by the Senate Law and Justice Committee; the bipartisan SB 120 cleared that committee in October 2025 and has sat there since, with a Senate discharge resolution presented June 29, 2026 [pa-legis-sb120]. Plan facility sizing on medical-only demand until a bill actually reaches the governor.

How electricity choice works in Pennsylvania

Pennsylvania opened retail electric choice under the Electricity Generation Customer Choice and Competition Act, 66 Pa.C.S. Sections 2801-2812, implemented under 52 Pa. Code Chapter 54, with commercial choice effective in 1999 [pa-puc-retail-markets]. Act 129 of 2008 amended default-service procurement rules to require a prudent mix of spot, short-term, and long-term supply [pa-puc-electricity].

All customers of Pennsylvania's investor-owned electric distribution companies, including every commercial and industrial class, may buy generation from a PUC-licensed Electric Generation Supplier [pa-puc-retail-markets]. The EDC continues to own the wires, deliver the power, and provide default service to customers who do not shop [pa-puc-retail-markets]. Eligible territories include PECO, PPL Electric, Duquesne Light, Met-Ed, Penelec, Penn Power, West Penn Power, UGI Utilities, Citizens' Electric, Wellsboro Electric, and Pike County Light and Power [pa-papowerswitch]. Rural electric cooperatives and municipal systems are outside the PUC choice framework [pa-puc-retail-markets].

The benchmark is the EDC's Price to Compare, the default-service generation plus transmission price for each rate class [pa-puc-retail-markets]. Under Act 129 default service is procured as a prudent mix of spot, short-term, and long-term supply and resets on a schedule: Duquesne's Default Service Supply rider can adjust up to four times a year, and PECO's Generation Supply Adjustment resets June 1 and December 1 [pa-puc-retail-markets]. Commercial PTCs differ by rate class, so a cultivation facility on a demand-metered class has a different benchmark than a small storefront dispensary [pa-puc-retail-markets].

Large commercial and industrial default service in most EDC territories is priced hourly off PJM rather than at a fixed PTC, which is the main reason facilities above the EDC's small-C and I demand threshold, commonly 100 kW to 500 kW depending on the EDC, shop for a fixed-price EGS contract [pa-puc-retail-markets]. All Pennsylvania EDCs sit in PJM, and capacity and network transmission costs pass through to EGS customers based on the customer's peak load contribution and network service peak load tags set by the EDC [pa-puc-retail-markets]. A grow room's summer coincident peak sets a full year of capacity cost regardless of which supplier it uses [pa-puc-retail-markets].

The PUC publishes supplier lists and shopping tools through PAPowerSwitch, the official electric shopping website [pa-papowerswitch]. A fixed, index, or block-and-index contract must be read with PJM capacity pass-through in mind, because the supplier quote and the delivery bill both respond to the same summer peak half-hours.

What commercial power costs in Pennsylvania vs. the U.S.

Sector	Pennsylvania, June 2026	U.S. average, June 2026
Commercial	13.33 cents/kWh	14.19 cents/kWh
Industrial	10.10 cents/kWh	not shown in state file

Source: EIA Electric Power Monthly, Table 5.6.A [eia-epm-5-6-a].

Pennsylvania commercial power runs about 6 percent below the national average. The bigger number for a grower/processor is the 3.23 cent gap between the commercial and industrial averages. That gap is mostly delivery structure and load factor, not fuel. A facility that runs lights on a fixed schedule with a managed peak looks more like an industrial customer to suppliers and pays closer to the industrial figure. A facility with spiky demand pays commercial-class delivery on a high peak. Understanding how rate classes are assigned is the first lever; the EGS contract is the second.

The utilities and where they serve

Utility	Territory	Grid operator	Notes for cannabis operators
PECO	Philadelphia and five-county southeastern PA	PJM	Largest EDC; Rate GS, PD, HT with per-kW demand on larger GS loads [peco-rates-tariffs]
PPL Electric	29 counties central and eastern PA	PJM	GS-1 through LP-5 classes; hourly default for large C and I [pa-papowerswitch]
Duquesne Light	Pittsburgh, Allegheny County, part of Beaver County	PJM	GS through HVPS; DSS rider adjusts up to four times a year [duquesne-business-rates]
FirstEnergy PA (Met-Ed, Penelec, Penn Power, West Penn)	Roughly two-thirds of PA land area	PJM	Legacy rate districts; large C and I default is hourly priced [pa-papowerswitch]
UGI Utilities	Parts of Luzerne and Wyoming counties	PJM	Small EDC; customers may shop with an EGS [pa-papowerswitch]

The Duquesne Light page covers the Pittsburgh urban footprint. The Pennsylvania commercial rate page puts the major classes side by side with the EIA figures.

What the climate does to a grow's bill here

Pennsylvania is humid continental: cold, snowy winters in the north and west and warm, humid summers in the southeast. Statewide normals run to 5,701 heating degree days and 706 cooling degree days per year, so indoor cultivation is heating-heavy for most of the year with a concentrated summer dehumidification season [noaa-cag-pennsylvania]. Philadelphia and the lower Susquehanna valley see summer dew points in the upper 60s and low 70s F from June through August; the Allegheny Plateau is cooler but still humid, so latent load dominates summer HVAC sizing in sealed rooms [noaa-cag-pennsylvania].

For a sealed grower/processor that means winter envelope heat loss lets you use less mechanical cooling for much of the year, but June through August brings dehumidification peaks that often set the meter's highest half-hour. The cultivation page works through what that does to peak demand and PLC tags.

Incentives worth knowing

• PECO Ways to Save for Your Business (Act 129 Phase V). Prescriptive and custom incentives for non-residential customers under Act 129 Phase V, June 1, 2026 through May 31, 2031, covering LED lighting and controls, HVAC, variable-frequency drives, motors, and custom projects, with a small-business direct-install track [peco-biz-savings].
• PPL Electric Business Energy Efficiency Program (Act 129). Performance-based rebates for lighting, HVAC, refrigeration, VFDs, controls, CHP, and agricultural equipment, plus direct-discount offers for small businesses. Phase IV ran June 2021 through May 2026; confirm the Phase V measure list before designing a lighting retrofit around it [ppl-biz-savings].
• Duquesne Light Business Energy Efficiency (Act 129). Commercial and industrial rebates for lighting, HVAC, motors, and custom measures in the Pittsburgh service territory [duquesne-business-rates].
• Act 129 Demand Response programs. EDC-run peak demand reduction programs under Act 129 pay commercial customers to curtail load on called event days; a cultivation facility with flexible lighting schedules can enroll through a curtailment service provider such as the PECO program administered by CPower [cpower-peco-dr].

Incentive measure lists and budgets change on five-year Act 129 phases. Confirm current eligibility with the utility program before ordering fixtures.

Pennsylvania quirks that change the advice

Act 16 vertical grower/processor permits with a hard cap. Pennsylvania issues combined grower/processor permits capped at 25 statewide, with no more than five also holding dispensary permits [pa-doh-growers-processors]. A small number of large, sealed indoor facilities carry most of the state's cultivation load, and new capacity comes from expansions of existing permit holders rather than new entrants.

Act 129 funds both efficiency rebates and default-service rules. Act 129 of 2008 is the reason every Pennsylvania EDC runs a business efficiency program on five-year phases, Phase V began June 1, 2026, and it also rewrote Section 2807(e) of the Competition Act to require default service to be a prudent mix of spot, short-term, and long-term supply, which is why PTCs reset on a fixed calendar rather than tracking the market month to month [pa-puc-electricity].

One ISO, many EDC territories. Every Pennsylvania EDC is in PJM, which simplifies capacity math compared with states split across two ISOs, but Met-Ed, Penelec, Penn Power, West Penn, PECO, PPL, and Duquesne each bill delivery on its own tariff with different class thresholds [pa-papowerswitch]. A multi-site operator with stores in Philadelphia and a grow in Lancaster County is still in PJM but crosses two EDC footprints.
