How the California gas options differ
SoCalGas distinguishes core aggregation from noncore supply arrangements. Its CAT program separates the aggregator’s commodity charges from utility transportation charges and explicitly says savings are uncertain.
Identify core or noncore classification before requesting bids. A SoCalGas program description does not establish eligibility on PG&E, SDG&E or a municipal system.
Utility and commercial service map
This map covers the utility routes represented by our California city guides. It is not an exhaustive statewide utility or supplier roster. A community or county listing does not confirm an individual service address.
| Gas service company | Review route | Classification to establish |
|---|---|---|
| SoCalGas | SoCalGas core aggregation | Core or noncore classification; CAT participation and the accepted agent |
| San Diego Gas & Electric | SDG&E Core Aggregation Transportation | Core or noncore service and the applicable CAT eligibility category |
| PG&E | Core Gas Aggregation Service | Commercial core schedule, including G-NR1 or G-NR2 where applicable |
| Long Beach Utilities | Long Beach Utilities commercial service | Long Beach municipal commercial gas class |
SoCalGas: SoCalGas core aggregation
SoCalGas separates an aggregator’s commodity service from utility transportation. Its CAT guidance expressly says that switching does not assure savings. Establish core or noncore status before using an aggregator proposal as the benchmark.
Cost scope: Aggregator commodity and customer fees versus utility procurement, with delivery retained. Operating question: Who supplies, balances and bills the account; conditions for returning to utility procurement.
Socal Cat. SoCalGas: region map and community engagement municipalities.
San Diego Gas & Electric: SDG&E Core Aggregation Transportation
SDG&E’s CAT FAQ lists commercial schedule GN-3 and explains that the 120,000-therm annual requirement applies to a group of participating core customers. It describes a minimum one-year commitment. A chosen Gas Service Provider submits the direct-access request; SDG&E confirms the enrollment date and continues delivery service.
Cost scope: Provider supply scope versus SDG&E non-procurement charges. Operating question: GSP acceptance and the utility direct-access service request.
SDG&E: commercial CAT schedules, group requirements and billing. Sdge Area.
PG&E: Core Gas Aggregation Service
PG&E calls its optional third-party supply arrangement Core Gas Aggregation Service. The minimum 120,000-therm annual pool requirement applies to the Core Transport Agent’s combined pool; it is not an individual small-business usage threshold. Its guidance also describes a minimum 12-month customer commitment.
Cost scope: CTA supply price and fees; PG&E transportation and other charges remain. Operating question: Minimum program commitment, supplier agreement and utility meter-read timing.
Long Beach Utilities: Long Beach Utilities commercial service
Long Beach operates municipal gas service in Long Beach and Signal Hill. Its utility publishes local natural-gas rates. SoCalGas’s CAT guidance is not the enrollment rule for this municipal meter, and this California guide must not be confused with National Grid gas service in Long Beach, New York.
Cost scope: Municipal customer and usage/supply rate components. Operating question: Local commercial gas service rules and any separately qualified transportation.
Territory and program exceptions to keep visible
Long Beach Utilities is the municipal gas service route. Keep it separate from SoCalGas CAT and from the National Grid gas territory in Long Beach, New York; the shared city name does not imply a shared program. Long Beach source notes.
A practical California account decision
Ask who holds transportation capacity, balances daily volumes and issues each bill. Compare the utility procurement alternative with the same delivery and billing assumptions.
Record the utility’s legal service company, commercial rate code, billed unit and supply arrangement in one account row. Keep a separate row for each meter even where a supplier offers one master agreement. Normalize gas units before entering rates; compare constant supply prices and fees only after the available service and cost scope are clear.
