Complete Upstream Data: Each project includes all 51 database columns from PJM’s interconnection queue at the top level. This provides complete transparency with both standardized fields (normalized across all ISOs) and PJM-specific raw fields like project_number, maximum_facility_output, and is_behind_meter.

Data Updates: PJM queue data is updated monthly based on PJM’s New Services Queue reports. The API reflects the most recent interconnection queue data available.
Study Process: PJM uses a detailed multi-phase study process including feasibility, system impact, and facilities studies. The study status fields track progress through each phase.
Missing Coordinates: PJM data does not include latitude/longitude coordinates. Use the county, state, and transmission_owner fields for geographic analysis.
