EIA-860 Solar Generators

This is the utility-scale solar slice of the EIA-860 generator inventory, listing every operating solar generating unit along with its plant, location, owner, nameplate and net capacity, and in-service dates.

Overview

It adds solar-specific attributes such as panel tracking type (fixed, single-axis, or dual-axis) and tilt angle. Researchers and analysts can use it to map where solar capacity sits on the grid, gauge how design choices shape generation profiles, and track the buildout of utility-scale solar over time. The source is the EIA-860 annual survey, with the inventory refreshed monthly between full annual snapshots.
