Overview

report is daily_operations, system_outlook or ofo_outlook. label is the column ENVOY printed: Actual, Estimate or Forecast on daily_operations (forecasts reach three gas days ahead), cycle names on the outlooks. Daily operations measures, location then measure_key, in Dth unless the measure says otherwise: tsso = System sendout (demand, Dth/d); totaldeliveries = Total deliveries (demand, Dth/d); txnfueluse = Transmission fuel use (demand, Dth/d); totrecpts = Total receipts (supply, Dth/d); sepehr = El Paso, Ehrenberg (supply, Dth/d); septop = El Paso, Topock (supply, Dth/d); stwnnd = Transwestern, North Needles (supply, Dth/d); stwtop = Transwestern, Topock (supply, Dth/d); skmkj = Kern River/Mojave, Kramer Junction (supply, Dth/d); skmwr = Kern River/Mojave, Wheeler Ridge (supply, Dth/d); spge = PG&E, Wheeler Ridge (supply, Dth/d); snbpbly = North Baja, Blythe (supply, Dth/d); stgnotay = TGN, Otay Mesa (supply, Dth/d); soxyr = Elk Hills, Wheeler Ridge (supply, Dth/d); line85 = California producers, Line 85 (supply, Dth/d); coastal = California producers, North Coastal (supply, Dth/d); cpnorth = California producers, North Desert (supply, Dth/d); cpsouth = California producers, South Desert (supply, Dth/d); cpwr = California producers, Wheeler Ridge (supply, Dth/d); others = California producers, other (supply, Dth/d); totinjwd = Net storage injection (negative is withdrawal) (storage, Dth/d); ugsinv = Ending storage balance (storage, Mcf); maxnc = Injection capacity (capacity, Dth/d); maxwc = Withdrawal capacity (capacity, Dth/d); customerimbalance = Total daily customer imbalance (balancing, Dth); cumulativecustomerimbalance = Cumulative customer imbalance (balancing, Dth); strgwdrbal = Storage withdrawal for customer balancing (balancing, Dth); cwatemp = Composite weighted average temperature (weather, °F). Read the newest posted_at per (report, gas_day, label, location, measure_key). Published by SoCalGas.

Query contract: Preserve one canonical row per (report, gas_day, posted_at, label, location, measure_key) before aggregating.
Analysis rules: Select the newest posted_at per (report, gas_day, label, location, measure_key) before reading.Actual, Estimate and Forecast are different quantities; never mix labels in one series.
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.

Dataset	Description
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. Published by SoCalGas.
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. Published by SoCalGas.
SoCalGas Receipt Point CapacitySoCalGas · Per NAESB cycle	SoCalGas's receipt point and zone capacity by cycle: GrossOperatingCapacity, firm and interruptible nominations and scheduled quantities per receipt location (Blythe, Ehrenberg, Topock, North Needles, Kramer Junction, Wheeler Ridge, Otay Mesa, California producers) and per zone, in Dth. 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.
SoCalGas Storage Inventory by FieldSoCalGas · Daily (gas day)	SoCalGas's storage inventory by field from 2001, in Bcf: totalinventorybcf = Total storage inventory (storage, Bcf); alisocanyoninventorybcf = Aliso Canyon inventory (storage, Bcf); honorranchoinventorybcf = Honor Rancho inventory (storage, Bcf); lagoletainventorybcf = La Goleta inventory (storage, Bcf); playadelreyinventorybcf = Playa del Rey inventory (storage, Bcf). Aliso Canyon is the largest field and the one the CPUC caps. Rows with report = 'storage_inventory' hold the fields; the 70% / 90% / peak-day minimum quantities stopped in 2015. 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.
