About Srp Energy

This is unofficial documentation for the SRP Energy Usage API, covering how to retrieve hourly electricity usage and cost data from Salt River Project (SRP), an Arizona utility. The documented process involves three steps: authenticating with account credentials, fetching an xsrf-token, and calling the usage endpoint with a billing account number and date range to retrieve hourly consumption, generation, and cost data.

The API response includes hourly usage broken down by on-peak, off-peak, shoulder, and super-off-peak kilowatt-hours and costs. The documentation notes that time-of-use customers do not receive total kWh or total cost directly from the API and that these values must be calculated using the SRP TOU price plan formula, while EZ-3 customers see usage and cost split across the four peak categories instead of totals.

This resource is intended for developers building tools or integrations that need programmatic access to SRP customer energy usage data, such as home energy monitoring or automation projects. It documents an unofficial reverse-engineered API rather than an official SRP-published service.
