Data Catalog
Overview
ERCOT's public large-generation interconnection queue, with project identity, developer, proposed point of interconnection, transmission owner, technology, requested MW, queue status, and proposed or actual completion dates. Each posting is a snapshot, so current project claims must use the latest snapshot rather than count every vintage. Queue inclusion and proposed dates do not establish available transmission headroom, study outcome, approval, construction probability, or an operating asset. The official source is ERCOT's NP4-198 GIS Report.
