Rate Schedules & Tariff Analysis
SoCalGas C&I rate selection turns on the core vs. noncore classification. Core customers (smaller firm loads) take bundled rates and SoCalGas procures their gas; noncore customers (large C&I, generally >250 Mcf/day) take transportation-only rates and buy their own gas, choosing between firm (GT-F) and interruptible (GT-I) service. All rates are volumetric per-therm with a CPUC-set transportation margin; there are no electric-style demand charges. The 2024 GRC sets the revenue requirement and a multi-year attrition path that raises the transportation margin each year through 2027.
Southern California Gas Company (SoCalGas) Rate Schedule List
| Schedule | Applicability |
|---|---|
| GN-10 / G-10 / GT-10 | Core (bundled) and transportation options for commercial and EG customers |
| GT-F / GT-I | Noncore firm and interruptible transportation for large C&I |
| GM (Multi-Family) | Master-metered multi-family and commercial bundled service |

Southern California Gas Company (SoCalGas) Data Access FAQ
Does SoCalGas offer a Green Button data export for my business?▾
Yes. Through the Analyze Usage tool in My Account, C&I customers can export hourly and daily gas usage in ESPI-compliant Atom+XML or CSV via the Green Button link below the usage graph. Note that automated Green Button Connect My Data (CMD) is limited; automated third-party sharing runs through Portfolio Manager or aggregators.
How can a consultant access our SoCalGas billing data programmatically?▾
SoCalGas has no native API. Consultants typically use a UtilityAPI-connected platform (Utility ID: SoCalGas) after the customer authorizes My Account access, providing daily-synced billing, usage, and tariff data.
How do we get building gas usage into ENERGY STAR Portfolio Manager?▾
Enroll in SoCalGas Portfolio Manager Web Services: create a Portfolio Manager property, connect to SoCalGas, and submit a request at eebenchmarking.socalgas.com/ab802/. SoCalGas then auto-uploads aggregated monthly usage, refreshed monthly. Initial data delivery takes 3-6 weeks.
Can our facility choose its natural gas supplier?▾
Eligible residential, small commercial (under 250,000 therms/year), and NGV customers can choose a registered Core Transport Agent (CTA) under the Core Aggregation Transportation (CAT) program, while SoCalGas continues to provide transportation. A consolidated single-bill option is expected to launch in 2026.
