Rate Schedules & Tariff Analysis
Versant C&I total cost = PUC-regulated delivery + market supply. The verified January 2026 Standard Offer increase for medium commercial (to 12.80 cents/kWh, +23.2%) means supply procurement is the most volatile and controllable cost lever; CEP shopping can beat or fix the Standard Offer. Delivery is set by rate class and district; large/transmission customers on Rate T-1 (500 kW+, subtransmission) can manage demand charges and consider standby service if self-generating.
Versant Power Rate Schedule List
| Schedule | Applicability |
|---|---|
| General Service (small commercial) | Small non-residential |
| Medium General Service | Demand-metered medium commercial |
| Rate T-1 (Large / Transmission) | 500 kW+ at subtransmission voltage |
| Standard Offer supply | Default energy supply |

Limitations & Considerations
- ⚠Automated Green Button Connect My Data is not deployed at scale; Versant is 'not resourced to export customer data on any kind of scale beyond infrequent individual requests.'
- ⚠Hourly interval data is only available where AMI meters have been deployed (rollout ongoing since 2022); opt-out meters give monthly reads only.
- ⚠My Account retains only 12 months of billing history; longer histories require special request.
- ⚠Third-party portal access (Supplier Marketplace) is limited to ESM opt-in customers and licensed CEPs.
- ⚠Exact EDI transaction sets and X12 version must be confirmed with Versant's EDI team.
Versant Power Data Access FAQ
How is a Versant C&I bill structured?▾
It has two parts: PUC-regulated Versant delivery charges (by rate class and district — e.g., Medium General Service or Rate T-1) and a separately priced energy supply charge, which is either the Standard Offer or a Competitive Electricity Provider (CEP) you choose. Versant always handles delivery, metering, and billing.
What is the current commercial supply rate?▾
For the Bangor Hydro District, the medium-commercial Standard Offer is 12.80 cents/kWh effective January 2026 — up 23.2% from 10.39 cents in 2025. Large-commercial supply is indexed monthly to wholesale prices. Shopping a CEP can fix or lower the supply component; delivery charges are set separately by the Maine PUC.
Can we get programmatic/API access to usage data?▾
Not via a fully automated public API. Versant supports manual Green Button (ESPI XML) exports from My Account, automated daily feeds to ENERGY STAR Portfolio Manager through the Avangrid Energy Manager portal (commercial), and EDI for licensed CEPs. Versant has stated it is not resourced for bulk automated exports; full Connect My Data may require a PUC directive.
What rate schedule applies to a large facility?▾
Commercial/industrial customers with 500 kW or more of demand taking service at no less than subtransmission voltage in the Bangor Hydro District fall under Rate T-1. Smaller demand-metered accounts use Medium General Service, and the smallest use General Service. Confirm demand and energy charges in the January 2026 tariff PDFs.
How does a third party access our data?▾
Add them as an authorized user in My Account (12-month history), or, for suppliers, opt into the Electricity Supplier Marketplace so licensed CEPs can view enrolled-customer usage via the Supplier Marketplace Portal. For benchmarking consultants, enroll the account in the Energy Manager portal and grant ENERGY STAR Portfolio Manager access.
