Last Resort Service supply

Customer group	Product	Apr-Sep 2026	Oct 2026-Mar 2027 (proposed)
Commercial fixed	Six-month price	10.485 cents/kWh	16.581 cents/kWh [ripuc-lrs]
Commercial variable	Monthly elective	Per monthly table [ripuc-lrs]	Per monthly table [ripuc-lrs]
Industrial	Monthly only	10.038 to 17.851 cents/kWh across 2026 [ripuc-lrs]	Monthly [ripuc-lrs]

Seasonality

563 cooling degree days and coastal humidity drive summer cultivation peaks [noaa-cag-rhode-island]. Winter LRS supply runs sharply higher than summer for Commercial Group accounts [ripuc-lrs].

B-32 backup service note

B-32 backup service sits in the Industrial Group for LRS with G-32 [ripuc-lrs]. Facilities with generator backup should confirm whether backup meters are classified separately [ripuc-lrs]. Misclassified backup can complicate supplier enrollment [ripuc-lrs].

Reading RIPUC LRS tables

RIPUC publishes Commercial and Industrial LRS history and proposed future periods on one page [ripuc-lrs]. Use proposed October 2026 through March 2027 Commercial fixed 16.581 cents per kWh as the winter planning benchmark [ripuc-lrs]. Industrial monthly rows show wider swings than Commercial fixed [ripuc-lrs].

G-02 and G-32 demand charges require the Summary of Rates tariff; this page intentionally does not quote dollar per kW figures without that filing [ripuc-lrs].

June 2026 rate context

Rhode Island commercial and industrial averages converged near 22.7 cents per kWh in June 2026 [eia-epm-5-6-a]. Cannabis facilities should budget from account bills because statewide averages blend retail and industrial load [eia-epm-5-6-a]. Supplier contracts hedge LRS; they do not replace delivery demand on G-02 or G-32 [ripuc-lrs].

ISO-NE and Rhode Island RES

Rhode Island Renewable Energy Standard compliance flows through Rhode Island Energy billing [ripuc-electric]. Supplier contracts may include REC content above minimum [ripuc-electric]. Delivery demand on G-32 remains on the utility bill [ripuc-lrs].

Use RIPUC Last Resort Service tables for supply benchmarks and tariff docket 26-05-EL for demand dollars [ripuc-lrs].

Commercial Group optional variable LRS

Commercial Group may elect monthly variable Last Resort Service instead of six-month fixed [ripuc-lrs]. Variable tracked ISO-NE moves from 10.485 cents summer fixed to monthly industrial swings [ripuc-lrs]. Most retail stores prefer fixed supplier contracts or fixed LRS [ripuc-lrs].

Rhode Island Energy acquired from National Grid in 2022; tariff book and LRS groups unchanged for choice customers [ripuc-lrs]. Block Island and Clear River exceptions remain [ripuc-lrs].

How to read a Rhode Island Energy commercial bill

A typical demand-metered cannabis account on G-02 shows five charge groups [ripuc-lrs]:

1. Customer charge. Fixed monthly fee by delivery class.
2. Delivery energy. Cents per kWh for distribution and transmission energy components.
3. Delivery demand. Dollars per kW for the billing-period peak on G-02 or G-32 [ripuc-lrs].
4. Last Resort Service supply. Default generation price for Commercial or Industrial Group unless a registered supplier is listed [ripuc-lrs].
5. System Benefits Charge and riders. Efficiency and renewable program funding on the delivery side [ripuc-electric].

Only the supply line changes when you enroll with a nonregulated power producer [ripuc-electric]. Delivery demand on G-32 stays on the Rhode Island Energy bill [ripuc-lrs]. See understanding your commercial utility bill for a generic walkthrough.

Worked example: G-32 industrial cultivator

Assume a Warwick cultivation facility on G-32 with 280 kW peak and 2.4 million kWh per year on Industrial Group monthly Last Resort Service (all inputs):

Line item	Calculation
Energy at RI commercial average	2,400,000 x $0.2270 = $544,800/year [eia-epm-5-6-a]
Supply at January 2026 Industrial LRS	2,400,000 x $0.17851 = $428,424/year [ripuc-lrs]
Supply at May 2026 Industrial LRS	2,400,000 x $0.10038 = $240,912/year [ripuc-lrs]

Industrial LRS swung from 17.851 cents/kWh in January 2026 to 10.038 cents/kWh in May 2026 [ripuc-lrs]. A fixed twelve-month supplier contract removes that monthly volatility on supply; delivery demand still bills per kW from the tariff docket [ripuc-lrs]. Pull per-kW distribution and transmission from Summary of Rates R.I.P.U.C. No. 2095 before quoting total delivered cost [ripuc-lrs].

Cannabis market and rate class migration

All 55 licensed cultivators sit on Rhode Island Energy in Warwick, West Warwick, Cranston, Pawtucket, and Central Falls industrial space [ri-ccc-cultivator-list]. Canopy expansion that raises peak demand can move an account from G-02 Commercial Group with six-month fixed LRS to G-32 Industrial Group with monthly LRS only [ripuc-lrs]. That migration changes both delivery demand structure and default supply product in the same billing cycle [ripuc-lrs]. Model peak before energizing additional flower rooms or extraction lines [ri-ccc-cultivator-list].

Nine hybrid retail shops and up to twenty-four new licenses from the 2026 application round add Commercial Group meters with October and April LRS resets [ripuc-lrs]. Cultivation-heavy portfolios should not assume one supply benchmark across all accounts [ripuc-lrs].

Reading RIPUC Last Resort Service tables

RIPUC publishes Commercial and Industrial Last Resort Service history and proposed future periods on one page [ripuc-lrs]. Proposed October 2026 through March 2027 Commercial fixed price is 16.581 cents/kWh versus 10.485 cents for April through September 2026 [ripuc-lrs]. Industrial monthly rows show wider swings than Commercial fixed [ripuc-lrs].

G-02 versus G-32 demand tariffs

Delivery classes G-02 and G-32 bill distribution and transmission demand per kW [ripuc-lrs]. Current per-kW figures require Rhode Island Energy Summary of Rates in docket 26-05-EL [ripuc-lrs]. This page intentionally avoids quoting kW dollars without that filing [ripuc-lrs].

June 2026 EIA convergence

Rhode Island commercial averaged 22.70 cents and industrial 22.91 cents per kWh in June 2026 [eia-epm-5-6-a]. Cannabis-heavy load pulls both sectors upward in the state average [eia-epm-5-6-a]. Budget from account bills, not EIA averages alone [eia-epm-5-6-a].

B-32 backup and G-32 industrial grouping

B-32 backup service sits in the Industrial Group for Last Resort Service with G-32 [ripuc-lrs]. Generator backup meters should be classified explicitly with Rhode Island Energy [ripuc-lrs]. Misclassification can block supplier enrollment [ripuc-lrs].

October and April LRS planning

Use proposed October 2026 through March 2027 Commercial fixed 16.581 cents/kWh as winter planning benchmark [ripuc-lrs]. Industrial monthly LRS exceeded Commercial fixed by wide margins in January 2026 [ripuc-lrs]. Pull G-02 and G-32 demand from docket 26-05-EL before quoting kW dollars [ripuc-lrs].

Commercial versus Industrial LRS spread

Commercial fixed LRS 10.485 cents/kWh summer 2026 versus proposed winter 16.581 cents/kWh [ripuc-lrs]. Industrial monthly ranged 10.038 to 17.851 cents/kWh across 2026 [ripuc-lrs]. G-32 accounts need monthly review or fixed supplier contracts [ripuc-lrs].

Supplemental tariff and procurement detail

Pull G-02 and G-32 demand dollars from docket 26-05-EL before investor pro formas [ripuc-lrs]. June 2026 commercial and industrial averages converged near 22.7 cents/kWh [eia-epm-5-6-a]. B-32 backup classification affects supplier enrollment [ripuc-lrs].

LRS winter planning table

Commercial fixed LRS proposed 16.581 cents/kWh October 2026 through March 2027 versus 10.485 cents/kWh summer 2026 [ripuc-lrs]. Industrial monthly LRS swung from 10.038 to 17.851 cents/kWh across 2026 [ripuc-lrs]. G-02 and G-32 demand dollars live in docket 26-05-EL tariff [ripuc-lrs]. June 2026 statewide averages near 22.7 cents/kWh blend retail and industrial load [eia-epm-5-6-a]. Supplier contracts hedge LRS; delivery demand stays on Rhode Island Energy [ripuc-lrs].

Tariff docket cross-reference

Cross-reference RIPUC Last Resort Service tables with docket 26-05-EL demand charges before quoting kW dollars [ripuc-lrs]. Supplier hedges LRS; G-02 and G-32 delivery demand remain on utility bill [ripuc-lrs]. Block Island and Clear River customers cannot shop [ripuc-lrs].

Industrial LRS January peak

January 2026 Industrial LRS 17.851 cents/kWh illustrates winter supplier hedge value [ripuc-lrs].

LRS groups and delivery demand persistence

Rhode Island Energy Last Resort Service splits Commercial Group accounts on six-month fixed pricing from Industrial Group accounts on monthly pricing only [ripuc-lrs]. January 2026 Industrial LRS hit 17.851 cents per kWh, illustrating winter supplier hedge value for G-32 cultivators [ripuc-lrs]. Supplier hedges LRS energy; G-02 and G-32 delivery demand charges remain on the utility bill [ripuc-lrs]. Block Island and Clear River customers cannot shop supply and should be excluded from portfolio RFP scope [ripuc-lrs]. Cross-reference RIPUC tables with docket 26-05-EL demand charges before quoting dollars per kW [ripuc-lrs].
