Overview

Includes USACE Cumberland projects and non-power dams; registry membership does not mean TVA ownership or power generation.

Query contract

Preserve one canonical row per (location_id, snapshot_time, source_location_id) before aggregating.

Analysis rules

For current state, select the latest complete snapshot_time per location_id from tva.feed_snapshots for this table. A row_count of zero means empty; never fall back to an older nonempty snapshot.

Interpretation

snapshot_time is collection time. Check the source day/time labels before describing data as current.
Raw strings preserve source units, missing-value sentinels and estimation marks; source_record retains all source fields.

Dataset	Description
TVA Generator Interconnection QueueTVA · periodic publication, checked daily	Every request in the current TVA queue PDF, including serial, cluster, transitional and surplus requests. Preserves wrapped identifiers and cells, summer/winter/spring-fall MW, service type, study phase, queue date, forecast in-service date, generator technology, county/state and connection point. publication_label is the document date; snapshot_time is collection. Requested seasonal MW is not operating capacity or transmission headroom; select one latest snapshot and one seasonal capacity measure.
TVA Precipitation Gauge RegistryTVA · 6-hour collection	The 244 gauge identifiers, names and states available from TVA daily precipitation queries. No coordinates are supplied by this endpoint.
TVA Publication Snapshot CoverageTVA · each collection	One completion record per table, requested location and collection, including row_count=0. An empty latest publication withdraws older schedules. Collection timestamps indicate retrieval, not source observation freshness.
Advanced MetersEIA · annual (report year)	EIA-861 advanced metering: AMR, AMI and other meter counts, AMI energy served and customer access, by utility and customer class. Advanced_Meters, one row per utility, state, balancing authority and customer class. customer_class is residential, commercial, industrial, transportation (direct_connected in the distributed generation tables) or EIA's own total, so summing classes without excluding total counts everything twice. event_time is 1 January of the report year. release is final or early_release: EIA posts an early release of a year in August and replaces it with the final file in the autumn, and the mirror keeps the newest row per key. A key cell EIA leaves blank is '' or 0, and duplicate_index numbers rows that still share a key, in workbook order.
