Rate Schedules & Tariff Analysis
Liberty C&I bills split into regulated delivery (customer charge + demand $/kW + per-kWh distribution/transmission) and a separate energy-supply charge (Default Energy Service ~$0.12420/kWh non-TOU, or a competitive supplier). For demand-metered classes G-1/G-2/G-3, demand charges dominate the delivery side, and G-2 adds a sizable $25.71/kW transmission demand charge. The supply component is where deregulated shopping creates savings.

Liberty Utilities (Granite State Electric) Data Access FAQ
How does a C&I customer or consultant get interval data from Liberty?▾
Submit the Interval Data Request (IDR) form with a customer Letter of Authorization. The first request per calendar year is free; subsequent single-account requests are $55, additional accounts $23 each, and an annual subscription is $309 for one account ($277 per additional account). Data is daily granularity, delivered in 5-10 business days as CSV/Excel.
Can a competitive supplier access Liberty customer usage via EDI?▾
Yes. Enrolled competitive energy suppliers receive usage via EDI 867 and exchange 814/810/820 transactions in ANSI X12 004010. Enrollment requires the NH Supplier Application, a signed service agreement, EDI pre-testing, a $500 business initiation fee, and ISO-NE registration.
Which delivery rate schedules apply to Liberty C&I customers?▾
General Service G-1 serves large commercial/industrial demand-metered customers (with a critical-peak TOU variant, G-1 CPT); G-2 is long-hour large service; G-3 serves smaller demand-metered commercial loads; and V/T serve small general-service accounts. These are delivery (poles-and-wires) rates under NHPUC tariff No. 23.
Does Liberty offer Green Button or a public API?▾
No. Liberty has not implemented Green Button Download/Connect My Data or any public customer-data API. The proposed statewide ESPI platform (RSA 378:51) is uncertain due to repeal efforts (HB 723). Manual CSV/Excel export and the IDR form are the available options.
Can NH businesses shop for a competitive electricity supplier?▾
Yes. New Hampshire is deregulated, so Liberty C&I customers can buy their energy supply from a competitive supplier (CEPS) while Liberty continues delivery, or remain on Liberty Default Energy Service. The delivery charge is unaffected by the supply choice.
