Rate Recommendations by Use Case
Small commercial office or retail (under 10 kW)
Take Rate C-06 delivery (no demand charge) and shop supply against Last Resort Service.
C-06 has no demand charge, so the bill is driven by the 13.318 cents/kWh delivery rate plus supply; the biggest lever is the supply price.
- Download monthly CSV usage to baseline.
- Compare competitive supply offers to the posted LRS rate.
- Watch for variable-rate spikes.
Mid-size facility with demand over 10 kW
Use Rate G-02 and manage peak demand with EPO interval data.
G-02 adds $6.29/kW (and $9.61/kW over 10 kW) demand charges, so shaving coincident peaks directly reduces the bill alongside supply procurement.
- Enroll in Energy Profiler Online to find peaks.
- Stagger equipment startup to cut coincident demand.
- Confirm G-02 vs C-06 fit based on load factor.
Large industrial / high-demand plant (over 200 kW)
Take Rate G-32, pursue high-voltage delivery discounts, and actively procure supply.
G-32 carries $7.57/kW (plus $8.08/kW over 200 kW) demand charges; HV delivery/metering discounts and second-feeder economics materially affect cost, and supply procurement is large enough to warrant a managed strategy.
- Take delivery at high voltage where feasible for discounts.
- Use interval data for demand-response and peak-shaving.
- Lock supply ahead of the semiannual LRS reset.
Multi-building portfolio / benchmarking
Enroll buildings in the Building Data Portal and sync to ENERGY STAR Portfolio Manager.
Whole-building aggregate data plus Portfolio Manager sync supports benchmarking, EUI tracking, and identifying the worst-performing sites to prioritize.
- Use the Tenant Authorization form for multi-tenant buildings.
- Authorize consultants via separate portal enrollment.
- Combine with EPO for interval-level diagnostics.

Cost Optimization Strategies
C&I customers can lower bills by separately optimizing supply procurement and demand (kW) on the regulated delivery side.
Shop competitive supply
For: All C&I rate classes (C-06, G-02, G-32)
Compare Last Resort Service against licensed competitive suppliers and consider fixing the supply price ahead of the semiannual LRS reset.
Manage peak demand (kW)
For: G-02 and G-32 demand-metered accounts
Use EPO interval data to identify and shave coincident peaks; demand charges of $6.29-$9.61/kW (G-02) or $7.57-$8.08/kW (G-32) make peak reduction valuable.
Verify rate-class fit
For: All C&I
Confirm the account is on the lowest-cost applicable class; small steady loads may fit C-06 (no demand charge) while high load factors may favor G-02/G-32.
Pursue high-voltage discounts
For: Large-demand HV customers
Customers taking delivery/metering at high voltage (incl. 69kV) qualify for delivery and metering discounts on G-32/B-32.

Frequently Asked Questions
How does a commercial customer get 15-minute interval data?▾
C&I customers request Energy Profiler Online (EPO) access by calling 1-855-743-1101. EPO provides retail interval load profiles by day, week, and month. The first two weeks per calendar year are free under the Optional Interval Data Service tariff; additional access incurs fees. As AMF meters are deployed, 15-minute data also becomes available through the customer portal.
Can a consultant or ESCO access my facility's data on my behalf?▾
Yes. The customer authorizes the third party (by phone at 1-855-743-1101 or via portal settings, and via the Tenant Authorization and Energy Usage Release Form for buildings). The third party then enrolls separately in EPO or the Building Data Portal, or receives a utility-provided CSV export limited to the authorized period and scope.
Should our business shop for a competitive supplier?▾
Rhode Island is a deregulated supply market, so C&I customers can buy generation from Last Resort Service (the default) or a licensed competitive supplier while delivery stays with Rhode Island Energy. Shopping can fix or lower the supply price (the largest variable bill component); compare against the posted Last Resort Service rate and watch contract terms and renewal/cancellation provisions.
Does Rhode Island Energy support Green Button or a public API?▾
Not currently. There is no Green Button DMD/CMD program and no public developer API at the utility. Data access is via portals (EPO, Building Data Portal, MyMeter), CSV/Excel downloads, ENERGY STAR Portfolio Manager sync, and (for suppliers) ANSI X12 EDI. Nectar provides API access to this utility's billing and interval data — see docs.nectarclimate.com.
Which delivery rate applies to my commercial account?▾
Small commercial/industrial accounts under ~10 kW take Rate C-06; general C&I with demand over 10 kW take Rate G-02 (which adds demand kW charges); large-demand accounts (generally over 200 kW) take Rate G-32. Each is a regulated delivery tariff on file with RIPUC; the supply portion is separate and can be shopped.
