Bayou Energy April 2026 Utility API Update

Overview

• New Utility Support: Five new utilities adding over 4 million US electric meters, bringing Bayou's coverage to 70% of the US electric market. And BC Hydro — our first Canadian utility — adds another 1.9 million.
• API Improvements: The /utilities endpoint now supports filtering by utility ID, and the intervals API now includes account number data and filtering.
• Revamped user and environment management: A single Bayou partner (company) can now have multiple company accounts -- one primary account and additional accounts for testing. User sign-in accounts can be shared across these company accounts, by invitation.
• Utility Website Updates: Maintained reliable access through new MFA rollouts at three utilities and adapted to tighter bot detection at two more.

New Utility Support

We’ve added 5 new utilities added since November 2025 with instant support:

1. Consumers Energy
2. NV Energy
3. The United Illuminating Company
4. Green Mountain Power
5. BC Hydro

The four US additions represent approximately 4.1 million electric meters, bringing Bayou's US electric meter coverage to 70%. Consumers Energy and NV Energy also serve gas customers — 1.7 million and 145,000 meters respectively — and Bayou returns gas bill data for those meters as well.

BC Hydro serves approximately 1.9 million meters in British Columbia and is Bayou's first Canadian utility, marking the beginning of our international expansion.

We're targeting 78% of US electric meters (covering all the large utilities in the US) by June, including Smart Meter Texas, Salt River Project, PSEG Long Island, and Alabama Power.

Revamped user and environment management

Previously, a company could have up to 2 accounts: one test account in the Bayou staging environment and one production account in the Bayou production environment. Now, companies can simply create a primary account, and one or more additional company accounts to use for testing. All accounts exist in the Bayou production environment, improving stability for the test accounts.

Users can be invited to join company accounts via email as always, but a single user account is now be able to join multiple companies.

Companies and users who onboarded prior to this change can continue to use their existing accounts on both Bayou environments (production and staging), or create a new test account in production and retire their staging account. To access existing staging accounts, use https://staging.bayou.energy/users/sign_in.

API Improvements

Filter /utilities by Utility ID

The /utilities endpoint now accepts a utility_id parameter, making it easy to fetch support details and performance metrics for a specific utility without retrieving the full list. API reference.

Account Number in Intervals API

The intervals API now includes account_number in the response data and supports filtering by account number. This makes it easier to match interval data to specific accounts when a customer has multiple account numbers.

Utility Website Updates

Utility portals change constantly — new MFA requirements, tighter bot detection, full redesigns. Keeping up with these changes across dozens of utilities is core to what Bayou does.

• Ameren, Versant Power, and Public Service of New Mexico (PNM) all rolled out new MFA requirements. We added full support for each, with long-lived MFA sessions to preserve your ability to receive ongoing data.
• PSEG New Jersey and Avangrid utilities (including CMP and NYSEG) tightened their bot detection. We adapted our authentication flows to maintain reliable access.
• Duke Energy — Following the portal overhaul we flagged in November, we added business account support.

MFA remains one of the biggest factors affecting utility data access — if you're seeing MFA-related issues, check out our post on How MFA/2FA Impacts Utility API Access.
