About this data

Each record is one project in NYISO's interconnection queue at a posting, with developer, location, transmission owner, technology, requested capacity, status and proposed or actual completion dates. It spans active, cluster-study, withdrawn and in-service projects. Requested MW is not operating capacity or available transmission headroom, and because each posting is a full snapshot, current totals come from the latest one.
