Query the CAISO generator interconnection queue — California ISO's public Public Queue Report, the waiting line of projects that have REQUESTED to connect to the CAISO grid (California, plus the out-of-state edges it studies: NV, AZ).

Returns cited, project-level records with CAISO's full published structure: the net megawatts to grid (net_mw_to_grid, CAISO's own headline figure) and the per-component Type/Fuel/MW triplets for hybrids (type_1..3, fuel_1..3, mw_1..3, plus an is_hybrid flag), the as-reported application_status, the cluster study_process (C01..C14, plus serial/legacy tracks), the three-valued deliverability status (deliverability_status = Full Capacity / Partial Capacity / Energy Only) with tpd_allocation_percentage / tpd_allocation_group / offpeak_deliverability, location (state, county, derived county_fips, utility, pto_study_region), the per-phase study statuses, and lifecycle dates (ir_receive_date, queue_date, proposed_online_date, current_online_date, and — for completed projects — actual_online_date). Group or filter by application_status, state, county_fips, deliverability_status, study_process, fuel_1, type_1, utility, pto_study_region, offpeak_deliverability, tpd_allocation_group, suspension_status, ia_status, or (group only) is_hybrid; filter queue_date by the queue_date_from / queue_date_to range. Pass each parameter as a top-level key of params (flat — not nested). Example: {"application_status": "ACTIVE", "fuel_1": "Battery", "state": "CA"} for active battery requests in California; {"group_by": ["application_status"]} for net MW and project counts by status; {"application_status": "ACTIVE", "group_by": ["deliverability_status"]} for the active pipeline split by deliverability. Returns JSON aggregates with citations and optional row-level records when include_records is true; every value carries source, as_of, and a source_row verifiable with get_source_evidence_v1.

net_mw_to_grid is REQUESTED capacity, not built: historically the large majority of queued megawatts withdraw before they are built, so the report is withdrawn-dominated. NEVER read a queue-MW total as installed or operating capacity — it is additive across distinct projects but is a REQUESTED total only. Scope by application_status: ACTIVE is the live pipeline, COMPLETED is built and in service (and carries an actual_online_date), WITHDRAWN left the queue. CAISO publishes no separate built-MW column — net_mw_to_grid is served under CAISO's own name and never relabeled or duplicated as a built figure. For built/operating capacity use query_power_capacity_v1.

CAISO only — never summed, deduped, or compared across ISOs. For the MISO interconnection queue use query_power_interconnection_queue_v1; for PJM use query_power_interconnection_queue_pjm_v1 (or query_power_interconnection_queue_pjm_cycle_v1 for PJM's cluster/cycle grid); for the NYISO (New York) queue use query_power_interconnection_queue_nyiso_v1; for the ISO-NE (New England) queue use query_power_interconnection_queue_isone_v1; for the ERCOT (Texas) queue use query_power_interconnection_queue_ercot_v1; for the SPP (central US) queue use query_power_interconnection_queue_spp_v1. This tool serves CAISO's Public Queue Report (Cluster 14 and prior, plus the serial/legacy tracks); CAISO's separate current-cluster intake file is a distinct publication and is not served here. CAISO reports no data-center / load type, and this tool does not infer one — that interpretation is the analyst's, from cited rows.
