Arcadia is a clean-energy access and energy-intelligence company that operates Arc, a utility data platform giving developers programmatic access to utility bills, statements, meters, interval (15-minute) usage data, tariff rates, and provider metadata across thousands of US and international utilities. Arc combines the Plug API for utility data, Arcadia Connect for hosted credential collection and MFA, Signal for tariff and rate calculations, and webhooks for asynchronous events. Arcadia powers solar and storage modeling, EV charging, energy management, property management, and carbon accounting for customers including Ford, EVgo, Enphase, Oracle, UPS, Conagra, Penske, and ~25% of the Fortune 500. In April 2026 Arcadia acquired ENGIE Impact, adding utility bill management, energy procurement advisory, and sustainability reporting capabilities.

The Arcadia Plug API is the flagship developer surface of the Arc data platform — programmatic access to utility bill, statement, meter, interval, site, and provider data sourced from thousands of US and international utilities. Plug powers solar/storage modeling, EV charging, energy management, property management, and carbon accounting use cases. OAuth 2.0 client-credentials authentication; versioned via the Arcadia-Version header (current default 2024-02-21).

Arcadia Connect is a hosted credential-collection web experience that handles utility account onboarding — credential capture, MFA flows, one-time passcodes, and credential refresh — without requiring partners to handle utility passwords directly. The accompanying Connect API generates encoded session URLs and exposes credential lifecycle endpoints (create, update, refresh, disable).

The legacy Utility Cloud REST API — predecessor to the Plug API — still documented for existing integrations. New integrations should use the Plug API; the Utility Cloud version remains available for backward compatibility.
