DOCUMENTATION

CAISO (California) Hourly Wind and Solar Energy Generation

Overview

This data product provides hourly solar and wind actual and forecast generation in MW in California ISO.

The ISO is focused on the reliable integration of zero-emission resources such as solar and wind power in support of the state's renewables portfolio standard. With this product, you will see the hourly generation in the three main trade hubs in CAISO.
