Interval Data & Smart Meters

Liberty has not deployed Advanced Metering Infrastructure for its Massachusetts gas system. Meters are read on monthly billing cycles (with automated meter reading rolled out for drive-by reads), so no 15-minute, hourly, or daily interval data is available to customers or third parties. Suppliers can request historical usage data manually, with fees for repeat requests.

Meter Technology
Traditional monthly-read gas meters with automated meter reading (AMR) for billing reads; no AMI interval recording
Gas Granularity
Monthly billed consumption only; no interval data

Rate Schedules & Tariff Analysis

Liberty's April 1, 2026 base rate reset (DPU 25-85) is the dominant driver of C&I gas costs in this territory — the first base distribution increase since 2015. Bill impacts skew heavily toward small C&I classes (up to ~49.7% as filed), while large C&I impacts are far smaller (as low as ~1.1%). Because the commodity portion (Cost of Gas Adjustment) is fully reconciled and Massachusetts allows supplier choice, large users can manage cost primarily through competitive supply procurement and load management, while delivery charges are fixed by tariff.

Liberty Utilities (New England Natural Gas) Data Access FAQ

How can my energy consultant get billing data from Liberty's Massachusetts gas utility?

Liberty has no API or third-party data portal. Your consultant needs a customer-signed Letter of Authorization, then contacts customer service at 1-800-544-4944 with the account number, service address, and specific data request. Liberty typically returns historical billing data within 1–2 business days. For recurring needs, customers can export 12 months of usage to a spreadsheet from My Account and share it.

Does Liberty New England Natural Gas offer interval or smart meter data?

No. Liberty has not deployed AMI on its Massachusetts gas system, so no 15-minute, hourly, or daily interval data exists. Consumption is captured at monthly billing reads. Competitive suppliers can buy historical usage data manually — the first request per account per year is free, then $55 per request or $309/year subscription per Liberty's supplier forms.

How much did C&I rates change in the 2026 Liberty rate case?

Under DPU 25-85 (filed June 2025, settlement approved March 27, 2026, rates effective April 1, 2026), the filing projected average bill impacts of +43.0% to +49.7% for small C&I in Fall River/North Attleboro, +43.0% to +46.7% for small C&I in Blackstone, +23.6% to +34.4% for medium C&I, and +1.1% to +19.2% for large C&I at class-average use. Final settled rates differ somewhat from the filing — check current tariff sheets for exact per-therm charges.

Can my business buy gas from a competitive supplier in Liberty's territory?

Yes. Massachusetts has retail gas choice. You can contract with a DPU-licensed competitive supplier for the commodity while Liberty continues delivery, billing delivery charges under its tariff. Suppliers enroll and exchange data with Liberty via its retail choice program using EDI 814/867/810/820 transactions and email-based nominations.

What data exchange does Liberty support for gas suppliers and brokers?

Registered competitive suppliers use ANSI X12 EDI (814 enrollment, 867 usage, 810 invoice, 820 payment) plus email-based nomination and trading forms (Liberty.Noms@libertyutilities.com). Brokers cannot access data directly — they must work through an appointed supplier. Onboarding includes a supplier service agreement, EDI pre-testing, training, and an initiation fee; expect roughly 4–6 weeks.

Does Liberty support Green Button for its Massachusetts gas customers?

No. There is no Green Button Download My Data or Connect My Data implementation, and Massachusetts does not currently require Green Button/ESPI for gas utilities. The closest equivalent is the My Account spreadsheet download covering about 12 months of usage.
