Delaware Adult-Use Sales Launched August 2025: First-Year Utility and Supply Decisions for New DE Grows

What launched in August 2025

Delaware opened adult-use cannabis sales on August 1, 2025 under the Marijuana Control Act [de-adult-use-launch]. The Office of the Marijuana Commissioner awarded 125 licenses through a December 2024 lottery, including cultivation, manufacturing, retail, and testing categories. Existing medical compassion centers converted first; lottery winners hold conditional licenses until they secure sites, complete buildout, and pass inspection.

For energy planners, the launch created a wave of first-time cultivation meters in a small state served mainly by Delmarva Power in PJM. Facilities energizing in 2025 and 2026 hit a supply market already stressed by PJM capacity prices and Delmarva Standard Offer Service (SOS) increases [de-sos-increase-2026].

Delaware's June 2026 average commercial rate was 14.40 cents/kWh [eia-epm-5-6-a], close to the national commercial average. Indoor grows on demand-billed schedules see higher effective rates once kW charges are allocated over cultivation load factor.

Delmarva choice: SOS benchmark vs supplier contract

All Delmarva Power Delaware customers may buy generation from PSC-certified competitive electric suppliers [de-psc-electric-choice]. Delmarva continues to deliver power and bill for distribution.

Customers who do not shop receive Standard Offer Service. Small and medium commercial classes get fixed-price full-requirements SOS from PSC-supervised reverse auctions. Larger non-residential accounts default to Hourly Priced Service (HPS), which tracks PJM hourly energy, capacity, and ancillaries [de-psc-electric-choice].

For a multi-room indoor grow likely to exceed medium general service demand thresholds, HPS default is volatile. Real-time prices spike on hot afternoons when HVAC and lighting coincide. Most operators shop a fixed or block-and-index supplier contract before energization. See how to switch in Delaware.

The PSC allows a three-business-day switch and a three-business-day rescission window on new supply contracts [de-psc-electric-choice]. Plan enrollment so supply starts the same billing cycle the meter goes live, avoiding a gap on utility default.

June 2026 SOS increase and what it signals

Delaware state news reported upcoming Delmarva electricity increases of roughly 18 to 20 percent for customers on default supply effective June 1, 2026 [de-sos-increase-2026]. SOS is not a subsidy; it reflects procured wholesale power plus administrative adders. When PJM capacity clears at elevated levels, SOS auctions embed those costs.

PJM's 2026/2027 capacity auction cleared at $329.17 per MW-day for much of the footprint, with costs flowing to bills starting June 1, 2026 [enel-pjm-capacity-2026]. Supplier contracts also pass capacity through based on your peak load contribution (PLC).

Customer path	Price behavior	Typical grow fit
Small/medium SOS fixed	Changes at auction reset	Small veg/processing only
Large HPS default	Hourly float	Rarely ideal for flower rooms
Competitive supplier fixed	Locked energy component	Most indoor cultivators

Even with a fixed supply contract, transmission and distribution riders on the Delmarva bill still move. The July 9, 2026 interim rates in Delmarva's base rate case (Docket 25-1555) adjusted delivery charges on medium and large general service [de-delmarva-rate-case].

First-year decisions for new cultivation buildouts

Size the service for peak, not nameplate fixture wattage. Delmarva medium and large general service schedules bill distribution demand per kW [de-psc-electric-choice]. Request interval data from similar facilities if your engineer lacks a load model.

Shop supply before conditional license conversion finishes. Conditional licensees often underestimate lead time for line extensions. Parallel-path utility engineering and supplier credit review.

Model PJM PLC. Your supplier assigns capacity charges from your PLC tag. Stagger flower rooms to avoid setting PLC during a single August afternoon. Details in demand charges explained.

Split delivery vs supply in pro formas. Investors comparing Delaware to Pennsylvania or Maryland should note Delaware's full choice but rising SOS. A 15 percent supplier discount vs SOS can disappear if delivery demand charges jump in the rate case.

Track June 1 and December 1 SOS periods. Even if you shop, SOS resets anchor supplier pricing and customer expectations [de-psc-electric-choice].

Worked example: 12,000 sq ft indoor on MGS-S

Assume 12,000 sq ft flowering canopy, LED at 32 W/sq ft, staggered rooms:

• Connected lighting load: ~384 kW nameplate
• Coincident peak with HVAC: ~140 kW if three rooms offset; ~280 kW if synchronized

Energy (rough): 280 kW × 12 h × 30 d × 0.55 load factor ≈ 166,000 kWh/month (modeling input).

At 14.40 cents/kWh average commercial [eia-epm-5-6-a], energy alone ≈ $23,900/month. Add $8 to $12 per kW-month distribution demand on 140 kW (verify current tariff) plus capacity pass-through at $329.17/MW-day on PLC [enel-pjm-capacity-2026].

Effective rate often lands 19 to 26 cents/kWh for indoor cultivation.

Municipal and cooperative exceptions

Newark, Dover, Milford, and other municipal electric departments, plus Delaware Electric Cooperative territory, are outside PSC retail choice [de-psc-electric-choice]. Lottery cultivators in those towns cannot shop suppliers. Confirm service territory before signing a lease.

Checklist for OMC license holders energizing in 2026

1. Confirm Delmarva rate class with expected peak kW
2. Request supplier quotes 90 days before target energization
3. Compare fixed offers to current SOS for your class [de-sos-increase-2026]
4. File switch paperwork with aligned start date
5. Install interval monitoring before first harvest
6. Calendar June 1 PJM capacity year and SOS resets
7. Revisit contract before auto-renewal if footprint changes

Hourly Priced Service vs fixed supplier for large grows

Delmarva large non-residential customers default to Hourly Priced Service passing through PJM hourly prices [de-psc-electric-choice]. A 200,000 kWh/month indoor facility on HPS default during an August heat wave can see effective supply costs spike without warning.

Fixed supplier contracts cap energy component; still read capacity pass-through [enel-pjm-capacity-2026].

Delmarva base rate case and delivery

Docket 25-1555 interim rates effective July 9, 2026 adjust delivery on medium and large general service [de-delmarva-rate-case]. New cultivators sizing service should use post-interim tariff sheets for demand charge budgeting.

Lottery license conversion timeline vs utility lead time

OMC conditional licenses require buildout before active status [de-adult-use-launch]. Utility line extension may exceed 12 months in constrained feeders. Submit service application when site control is signed, not when OMC approves final inspection.

Municipal utility exceptions revisited

Newark Electric Department and other municipal utilities sit outside PSC choice [de-psc-electric-choice]. Site selectors comparing Wilmington Delmarva vs Newark municipal must model total cost, not only lease rate.

PJM PLC for new meters

First summer operating sets initial PLC with limited history [enel-pjm-capacity-2026]. Stagger rooms from day one before bad habits lock high PLC for twelve months.

Co-op territory note

Delaware Electric Cooperative members cannot shop PSC-certified suppliers [de-psc-electric-choice]. Confirm co-op territory maps before lease signing.

Expanded checklist for 2026 energizations

1. Confirm Delmarva rate class with engineer letter
2. Shop supply 90 days before meter activation
3. Avoid HPS default on large accounts [de-psc-electric-choice]
4. Calendar June 1 SOS and capacity year [de-sos-increase-2026]
5. Track Docket 25-1555 delivery outcomes [de-delmarva-rate-case]
6. Use Delaware switching guide

Adult-use demand is new; default supply pricing already reflects a tight PJM capacity market. Treat supplier choice as part of license conversion, not an afterthought once the first harvest hits the meter.

Why Hourly Priced Service punishes flower rooms in August

Delmarva assigns large non-residential customers who do not shop to Hourly Priced Service, which passes through PJM real-time energy, capacity, and ancillary charges [de-psc-electric-choice]. A fixed supplier contract caps the energy component; HPS default does not.

Assume a 12,000 sq ft indoor facility with 166,000 kWh in August and a load factor near 0.55 (model inputs). On a day when PJM real-time prices spike during afternoon heat, hourly default customers pay those intervals directly. Fixed supplier customers pay their contract energy rate plus any capacity pass-through tied to PLC [enel-pjm-capacity-2026].

Supply path	August energy risk	Capacity risk	Best for
Small/medium SOS fixed	Reset at auction	Embedded in SOS	Veg, processing only
Large HPS default	Hourly float	Hourly float	Rarely cultivation
Competitive fixed	Locked energy	PLC pass-through	Most indoor flower

Delaware state news reported Delmarva Standard Offer Service increases near 18 to 20 percent effective June 1, 2026 [de-sos-increase-2026]. Even shoppers should note that benchmark: suppliers price against SOS when they quote fixed offers. PJM's 2026/2027 capacity auction cleared at $329.17 per MW-day for much of the footprint, flowing to bills starting June 1, 2026 [enel-pjm-capacity-2026].

Delivery charges move independently. Delmarva's base rate case Docket 25-1555 set interim rates effective July 9, 2026 on medium and large general service [de-delmarva-rate-case]. A 15 percent supplier discount versus SOS disappears quickly if distribution demand charges rise on your peak month. Stagger flower rooms before the first summer on meter so your initial PLC is not set during a single synchronized August afternoon [de-psc-electric-choice].

Lottery cultivators converting conditional licenses should submit Delmarva service applications when site control is signed, not when OMC approves final inspection [de-adult-use-launch]. Line extension lead times in constrained feeders can exceed twelve months. Parallel-path supplier credit review so enrollment aligns with meter activation using the Delaware switching guide three-business-day switch rules [de-psc-electric-choice].
