Ask the Grid's computed daily scheduled feedgas for US LNG export terminals: the latest posted schedule at each interstate delivery point that feeds a terminal, summed per terminal and gas day, in Dth/day (one Dth is one MMBtu).

Overview
Terminals: Plaquemines, Sabine Pass, Cameron, Calcasieu Pass, Freeport, Cove Point and Golden Pass. Coverage is partial: laterals with no collected bulletin board (Creole Trail, Cameron Interstate, Gator Express) are seen through the deliveries into them, Texas intrastate supply to Freeport and Corpus Christi is not posted, and Elba Island is excluded. posted_points against mapped_points says how complete a day is; the newest gas day often holds only next-day nominations. feeds lists each point, its route and the cycle its latest posting came from. These are nominations, not metered feedgas or a terminal's own figures, and they must be labelled as Ask the Grid's computed series.
Query contract
Preserve one canonical row per (gas_day, terminal) before aggregating.
Analysis rules
One row per terminal per gas day; sum terminals for a national total of the covered terminals only.Compare days only where posted_points equals mapped_points, or say how many points are missing.
Interpretation
A computed sum of pipeline nominations, not metered feedgas; call it Ask the Grid's computed scheduled feedgas.Partial coverage: Creole Trail, Cameron Interstate and Gator Express are seen only through deliveries into them, Texas intrastate supply is absent and Elba Island is excluded.

Rule-versioned candidate links between EIA plant gas declarations and native delivery contract points, preserving plant, pipeline, point and contract IDs and the evidence behind each candidate. The current rule requires a matching declared pipeline, proprietary point qualifier, delivery role, END/EGN native location type, geography and distinctive plant name. Read the latest whole event_time snapshot: earlier rule versions include superseded town, station and city-gate matches. A candidate does not prove a dedicated lateral, physical interconnection, available capacity, pipeline pressure, firm deliverability or actual fuel burn.
Provenance and content hashes for original public shipper-contract, firm, interruptible, capacity-release and offer reports, including advertised historical Algonquin and Texas Eastern archives and each individual archive member. The SQL table holds document metadata and original blob pointers, not extracted award economics or PDF text. Individual reports are separately indexed for document search. ZIP containers, overlapping monthly/full-year archives and repeated observations must not be counted as separate commercial transactions. observed_at is capture time; historical publication labels remain native text in titles and source records.
Native Index of Customers records from Algonquin, Tennessee, Texas Eastern and Transco, retaining H/D/A/P/F record types, shipper and contract identifiers, effective and expiration text, raw MDQ values and units, point qualifiers and parent row relationships. D records describe contracts; P records describe their points and are not additional contracts. These are contractual rights declarations, not metered gas flow or capacity-release awards. Use the latest snapshot separately for each pipeline and preserve native units before comparing quantities.
Pipeline-posted design, operating and operationally available capacity, with scheduled quantities in Dth/day (one Dth equals one MMBtu). Schedules are accepted nominations, not metered physical flow or plant fuel burn. Keep pipeline, native location ID, direction, gas day, source cycle and report vintage together. Explicit cycle/direction aliases are interpreted downstream; proprietary or historically guessed cycles remain unverified. Never infer a nomination cycle from a posting or effective clock. Available capacity is separately posted and can reflect commercial restrictions, netting or aggregation; zero availability with zero schedule does not establish full utilization. Central delivery points and named groups may overlap physical/member points. Do not sum these into system throughput or complete power-plant demand. Category tags are name-based classifications, not operator-confirmed facility links, and coverage is incomplete. Native evidence is retained in raw_record for source-preserving captures (capture_version 2); older Kinder Morgan and Enbridge captures lack reliable cycle evidence. Choose the latest whole report for one cycle and direction, preserving missing values rather than carrying cells or deleted locations forward. Check freshness and coverage separately for each pipeline.
