Time basis: Date-labelled records; UTC · event_time

Overview

Utilization is TotalScheduled over GrossOperatingCapacity for one location and cycle. cycle is ENVOY's NAESB cycle number: 1 timely, 2 evening, 3 intraday 1, 4 intraday 2, 5 intraday 3. Long format: one row per report, gas day (or hour), cycle, section, location and measure_key; measure is ENVOY's printed column name, and its trailing parenthetical is the unit. Published by SoCalGas.

Query contract: Preserve one canonical row per (report, event_time, cycle, section, location, measure_key) before aggregating.
Analysis rules: Read with FINAL.Compare one location within one cycle; later cycles restate earlier ones.
Interpretation: One utility's own system, not California-wide: PG&E and SoCalGas are separate systems, and neither includes the other's demand.Published by SoCalGas; attribute it to SoCalGas whenever it is reported.

SoCalGas Daily Operations ArchiveSoCalGas · Monthly archive of daily values	ENVOY's monthly Daily Operations archive from 1999: actual sendout, receipts by interconnect, storage and balancing per gas day. The current month is not archived until it ends; read socalgas_envoy.outlook_snapshots label = 'Actual' for it. Same measures and units as the live posting under older keys (systemsendout, elpasoehrenberg, endingstoragebalance in Mcf, …). Long format: one row per report, gas day (or hour), cycle, section, location and measure_key; measure is ENVOY's printed column name, and its trailing parenthetical is the unit.

SoCalGas Hourly Receipts and StorageSoCalGas · Hourly	SoCalGas's hourly flow by receipt point and storage field (Aliso Canyon, Honor Rancho, La Goleta, Playa del Rey injection and withdrawal), in Dth per hour; event_time is the hour. Sum an hour's rows over a gas day for a daily total. Long format: one row per report, gas day (or hour), cycle, section, location and measure_key; measure is ENVOY's printed column name, and its trailing parenthetical is the unit.
