Interconnection queue

The ordered list of generation and large-load projects seeking grid connection through an ISO, RTO, or utility. Queue position, status, and withdrawal history indicate development pipeline pressure.

EIA-860

Annual and monthly (860M) surveys of U.S. electric generators — the authoritative inventory of operating, planned, and retired power plants.

ISO / RTO

Independent System Operator or Regional Transmission Organization — entities that manage wholesale electricity markets and grid reliability in regions such as ERCOT, PJM, and CAISO.

LBNL Queued Up

Lawrence Berkeley National Laboratory's harmonized national interconnection queue dataset, aggregating ISO/RTO queue records into a consistent schema.

Large-load interconnection

Grid connection requests for high-demand facilities such as data centers, manufacturing plants, and industrial campuses — often tracked separately from utility-scale generation.

HIFLD

Homeland Infrastructure Foundation-Level Data — geospatial layers for transmission lines, substations, and other critical infrastructure in the United States.

Queue backlog

The volume of active interconnection requests awaiting study, agreement, or commercial operation — often measured in megawatts and project count by region.

Source attribution

Per-record metadata identifying the originating public dataset, ingest timestamp, and change history — required for auditable infrastructure research.

Physical economy intelligence

Structured data on tangible infrastructure assets — power, manufacturing, logistics, and development pipeline — as distinct from financial markets alone.

Interconnection study

Engineering and economic analysis required before a project can connect to the transmission or distribution grid. Study timelines drive queue wait times.
