Taunton Municipal Lighting Plant (TMLP) Data Access Guide
Taunton Municipal Lighting Plant (TMLP) is a Massachusetts municipal light plant founded in 1897 serving roughly 40,700 customers across six southeastern Massachusetts communities. C&I customers access bills and usage analysis through portal.tmlp.com, and an AMI deployment (completed ~2022) puts interval data within reach — but Green Button, third-party programs, and APIs are not documented, so data access beyond the portal runs through direct requests to customer service.

Taunton Municipal Lighting Plant (TMLP) Data Access FAQ
How do commercial customers access TMLP billing and usage data?▾
Register at portal.tmlp.com using your most recent bill. The portal provides current and historical bills (PDF), payment history, unbundled rate components, and an analyze-and-download electricity usage function. CSV export is unconfirmed — call 508-824-6976 to verify download formats for your account.
Does TMLP provide interval meter data?▾
Likely yes for newer meters: TMLP completed an AMR/AMI deployment around 2022, and Massachusetts standards point to 15- or 30-minute granularity. The exact granularity and download format are not published — ask customer service specifically about interval meter data download options before designing an analytics workflow around it.
Can a consultant or aggregator access TMLP data for a customer?▾
Only through a manual process. There is no Share My Data portal, API, or aggregator integration. The customer signs a written authorization specifying the third party, data types, and duration; the third party submits it to Customer Service (508-824-6976) with the account number. Data arrives as PDF bills by email or via portal downloads the customer shares.
Does TMLP support Green Button or EDI?▾
Green Button: no — neither Download My Data nor Connect My Data is documented, and TMLP is not a Green Button Alliance member. EDI: possibly for suppliers under Massachusetts EBT standards (EDI 4010), but no enrollment process is published; contact the Administrative Offices at 508-824-5844 for trading partner information.
What does Nectar's roadmap support level mean for TMLP accounts?▾
TMLP is on Nectar's roadmap: automated ingestion is planned but not yet productized. Today, Nectar works with TMLP data via customer-downloaded portal PDFs and usage exports or authorization-based manual requests while native support is built.
