Interval Data & Smart Meters
Unitil is deploying AMI smart meters across its Massachusetts territory. Electric customers with smart meters can view and download daily usage in the MyUnitil Smart Meter tab with a 90-day lookback. Hourly interval access and three-part TOU data provision to suppliers are under development; gas customers remain on AMR with billing-level data only.

Green Button Connect My Data with OAuth 2.0 and ESPI XML is in development, and Unitil appears on the UtilityAPI platform for certain service areas pending CMD launch.

- 02Monitor Massachusetts DPU 26-22 for the Green Button implementation timeline
- 03Once CMD is live: register as a Green Button Connect provider with Unitil, receive OAuth 2.0 credentials, and request customer authorization

- ⚠Green Button Connect My Data is announced but not yet live (DPU 26-20/21/22 pending as of May 2026).
- ⚠No formal third-party portal authorization; third parties rely on manual CSV sharing or supplier EDI relationships.
Fitchburg Gas and Electric Light Company (Unitil) Data Access FAQ
How do C&I customers export usage and billing data from Unitil in Massachusetts?▾
Log into MyUnitil at https://myaccount.unitil.com, open Bills & Payments, and use the Download feature to export up to 24 months of billed usage, payment history, or billing history as CSV — including multiple linked accounts in a single file. Daily electric smart-meter usage (90-day lookback) is downloadable from the Smart Meter tab.
Does Fitchburg Gas and Electric (Unitil) support Green Button Connect My Data?▾
Not yet. Unitil is actively developing Green Button Connect My Data under the Massachusetts 2024 Climate Act, with DPU dockets 26-20/21/22 and a public hearing held May 14, 2026. When live, third parties will register for OAuth 2.0 credentials and receive customer-authorized interval and billing data in ESPI XML. Until then, the workaround is manual CSV sharing from MyUnitil.
Can a third-party energy manager pull interval data automatically today?▾
No. Unitil offers no public REST API and no formal third-party authorization portal. Today the paths are: customer-exported CSV files from MyUnitil (daily electric, 90-day lookback), or EDI 867 transactions if your organization is a Massachusetts-licensed competitive supplier with a signed Trading Partner Agreement.
What EDI transactions does Unitil support for competitive suppliers?▾
Unitil certifies ANSI X12 v4010 transactions under the Massachusetts EBT guidelines: 814 (enrollment/change/drop/historical request), 810 (invoice), 820 (payment), 867 (historical and monthly usage), and 997 (acknowledgement). Enrollment starts with an email to EL_SupplierServices@unitil.com, followed by a Trading Partner Agreement, testing, and certification. Hourly 867 interval data for ISO-NE settlement is in development.
What interval granularity is available for Unitil electric accounts?▾
Daily granularity only, with a 90-day lookback through the MyUnitil Smart Meter tab. Hourly interval access is planned as part of Unitil's AMI rollout and ISO-NE hourly load settlement work, but 15-minute and hourly downloads are not available as of May 2026. Gas accounts remain on AMR meters with monthly billing-level data.
