Time basis

Point-in-time records

UTC · snapshot_time

Overview

Includes ongoing and future postings; timestamp timezone is unstated in the CSV.

Query contract

Preserve one canonical row per (location_id, snapshot_time, mrid, start_label, stop_label, source_record) 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 Lake Operating NoticesTVA · 15-minute collection	LakeInfo messages, effective-since labels and the source display-generation flag. Empty messages are retained, including changes withdrawing a notice.
TVA Transmission Line Outage PostingsTVA · hourly collection	TVA OASIS line outages with named terminals, native status code, MRID, start/stop labels and miscellaneous notes. Includes ongoing and future postings; a posted interval is not proof of an outage happening. The CSV does not state the timestamp zone: preserve the labels and do not invent UTC instants.
AlertsISONE · ISO-NE source publication	ISO-NE's published Alerts source feed. This catalog page exposes the physical schema, coverage, and latest source rows without inventing a normalized grain for publisher-shaped snapshot fields. Use the documented key and event time when comparing revisions or vintages.
BPA Planned Transmission OutagesBPA · every 6 hours	BPA's posted transmission outage plans (rolling year, monthly initial and final), every revision kept, one row per outage request.
