Utility Data Access Guides
Step-by-step instructions for accessing energy data from every major US utility. Portal downloads, Green Button, EDI feeds, API integrations, and 15-minute interval data — all in one place.
How to use these data access guides
Every utility has different portals, different data formats, and different processes for sharing energy data with third parties. Some offer Green Button Connect APIs, others require paper authorization forms. These guides document exactly how to access billing history, 15-minute interval data, and rate information from each utility — whether you're doing it yourself or authorizing a third-party platform like Nectar.
