About this data

Each record is one project in CAISO's Public Queue Report at a monthly posting, with its proposed point of interconnection, technology, requested capacity, status and completion dates. Active, completed and withdrawn projects are all included. Requested queue MW is not operating capacity, transmission headroom or evidence that a project will be built, and because every posting is a full snapshot, current totals come from the latest one.

What people use it for

  • Count the storage and solar projects requesting to connect in California
  • Follow withdrawals and completions across queue postings
  • Compare requested capacity by technology
