Upper Michigan Energy Resources Corporation (UMERC) Data Access FAQ

How do C&I customers get billing data from UMERC programmatically?▾

Large C&I customers can enroll in EDI 810 electronic billing (ANSI X12 / UIG) through We Energies' EDI Implementation team at 800-242-9137 — bills transmit the day they are prepared. For bulk historical data, the Customer Data Privacy Tariff guarantees 12 months of usage data free of charge, delivered the next business day in PDF, Excel, or Word.

Does UMERC support Green Button data access?▾

Not yet. MPSC Case No. U-20959 directs UMERC to implement Green Button or Green Button-compatible exports (NAESB REQ.21 / ESPI), including Connect My Data for third-party authorization, but the Commission set no deadline and implementation is still in progress. Until then, interval data is requested through customer service.

How do third parties access UMERC meter data on a customer's behalf?▾

Two paths: (1) written customer authorization submitted to customer service at 800-242-9137, with data returned in accessible formats within one business day; or (2) for Alternative Electric Suppliers and qualified service providers, a Meter Data Management Services Agreement with letters of authorization, granting access via UMERC's MDMS.

Does UMERC have smart meters and interval data?▾

UMERC is in the final stages of an AMI meter replacement project launched in 2020 across its electric territory, enabling daily reads and historical consumption tracking. Interval data can be requested through customer service in Excel or CSV, though published granularity specifics are limited. Gas AMI deployment is not documented.

What does Nectar's roadmap support level mean for UMERC?▾

UMERC is on Nectar's roadmap — automated ingestion is planned but not yet productized.
