CAISO: projects in the interconnection queue
255 solar, battery storage and wind projects that Groundtrace tracks in the California Independent System Operator’s queue are in development, 77,178 MW in all. Each one is joined to its permits, county records and satellite imagery, so the list below starts with the sites closest to breaking ground, not the newest requests.

About the CAISO queue
CAISO runs the grid for most of California. Its queue lists each request's size, fuel and point of interconnection, and whether its interconnection agreement is executed. It names no developer, so who is behind a California project comes from other records.

Questions
CAISO, in short.
How many projects in CAISO's queue are in development?
255 projects that Groundtrace tracks in CAISO's interconnection queue are in development, 77,178 MW in all, 35 of them under construction.
Which states do they sit in?
California and Arizona, most first.
Does a place in CAISO's queue mean a project will be built?
No. Most interconnection requests are withdrawn before construction. A signed interconnection agreement, a financing close, a construction permit or ground work seen from satellite says far more, and Groundtrace ranks projects by those signals, not by their queue date.
