Rate Schedules & Tariff Analysis
C&I customers are assigned to a G-class based on annual consumption and winter (heating) intensity. High Winter Use classes (G-41/42/43) suit heating-dominated buildings; Low Winter Use classes (G-51 through G-58) suit flatter, process-driven or higher-load-factor loads. The Cost of Gas is computed semiannually (summer May-Oct, winter Nov-Apr) separately for the High Winter and Low Winter C&I groups, with monthly adjustments capped at a cumulative 25% above the NHPUC-approved level. A revenue decoupling mechanism (Normal Weather Adjustment) was approved, separating distribution revenue from sales volume.
Liberty Utilities (EnergyNorth Natural Gas) Rate Schedule List
| Schedule | Applicability |
|---|---|
| G-41 / G-42 / G-43 — High Winter Use C&I | Heating-dominated commercial/industrial, by low/medium/high annual use. |
| G-51 / G-52 — Low Winter Use C&I (low/medium annual use) | Flatter commercial loads with lower annual consumption. |
| G-53 / G-54 — Low Winter Use C&I (high annual use) | High-annual-use industrial; G-54 for load factor >90%. |

- ⚠No Green Button Download/Connect My Data or customer-facing utility API yet (in development via statewide platform) — Nectar provides API access to billing data (docs.nectarclimate.com).
- ⚠No formal Share My Data / third-party authorization portal; direct utility third-party access is manual.
- ⚠Per-class dollar charges are set by NHPUC order in the rate sheets; specific $/therm figures should be confirmed against the current NHPUC No. 11 rate sheets.
Liberty Utilities (EnergyNorth Natural Gas) Data Access FAQ
Can my business get interval (hourly) gas data from Liberty EnergyNorth?▾
No. NH gas meters use AMR with monthly reads, so only monthly therm usage is available. There is no 15-minute or hourly gas interval data. Interval/AMI data may become available through the NH statewide energy data platform (NHPUC Docket DE 19-197).
Does Liberty offer Green Button or an API for C&I data?▾
Not yet. Green Button Connect My Data (ESPI) and a customer-facing API are in development via the statewide platform Liberty is helping govern. Today, the only options are CSV/Excel export from My Account or a customer-authorized manual export through Customer Care.
Which rate class applies to my commercial building?▾
C&I customers are assigned to a G-class based on annual consumption and winter-use intensity: High Winter Use (G-41/G-42/G-43) for heating-dominated loads and Low Winter Use (G-51 through G-58) for flatter loads. The exact class appears on the first page of your bill; confirm it with Customer Care.
Can a commercial customer buy gas from a competitive supplier?▾
Yes. New Hampshire allows energy choice for the gas commodity. A C&I customer can contract with a competitive supplier while Liberty continues to deliver and bill the regulated distribution charges. Default customers receive the semiannual Cost of Gas.
How do third parties access a customer's gas data?▾
There is no automated third-party portal today. With written customer authorization, a consultant can request bills/usage summaries from Customer Care (1-800-833-4200), typically delivered in 5-10 business days. Energy suppliers use EDI. Standardized API access is planned through the statewide platform.
