  • Utility Website Updates: Adapted to portal, MFA, and bill-format changes across more than a dozen utilities.
  • New Utility Support: Implemented support for United Power, adding 114k more electric meters in Colorado.
  • General Improvements: Improved the bill uploads feature, increased webhook URL length, and assorted reliability fixes for several utilities.

More info on these below, and check out our utility support page for detailed info on our coverage and reliability.

Structured Bill Details (Public Preview)

In addition to the top-line numbers like consumption and billed amounts, API users can now see individual charges, credits, and adjustments as discrete entries. This is useful for detailed breakdowns, anomaly detection, and deriving signals such as low-income indicators from utility-specific line items (e.g. LIHEAP grants).

The parsed line items are exposed via a new bill_details structure on the bill data model, which sits parallel to the existing data fields so it's a non-breaking change.

This is a public preview, gated per-company and live first for Ameren Illinois, ComEd, PNM, and Xcel Energy. If line item parsing or other bill details would be useful for your company, please reach out to [email protected].

Utility Website Updates

We continue to adapt as utilities update their portals, interfaces, and bill formats. Here are some of the changes that we updated for this month:

  • Portal login structure changes at Duke Energy, Avangrid Utilities (Central Maine Power, NYSEG, RG&E, United Illuminating, Berkshire Gas), Unitil, PSEG NJ, AEP Ohio, and FirstEnergy utilities.
  • New MFA support at Florida Power and Light
  • New adaptive MFA support at Consumers Energy
  • New bill format at Pepco
  • Handled new response codes for Exelon utilities (ComEd, PECO, BGE, Pepco, Atlantic City Electric, Delmarva)

New Utility Coverage

  • United Power (Colorado electric cooperative) — full support for authentication, bills, and intervals; adds ~114,000 meters in Coloroado

General Improvements

  • Improved bill upload attribution — when customers upload bill PDFs, Bayou now extracts the account number from the bill itself (PECO, PPL Electric, PNM).
  • Longer webhook URLs — max length raised from 200 to 2048 characters.
  • Added community-solar (CDG Credit) parsing for National Grid NY. This is returned in the community_solar_bill_credit field within the bill data model.
  • Bill and interval fetch reliability improved for PPL Electric, Rhode Island Energy, Eversource, FirstEnergy, Duquesne Light, Central Hudson, Xcel Energy, PNM, and SCE.
  • Bill parsing improved for FirstEnergy utilities, Rhode Island Energy, ComEd, Central Maine Power, Southern Company, Atlantic City Electric, and AES Ohio/Indiana.
