California: Trace a change from filing to the affected account
Start with FERC: interstate and intrastate pipeline responsibilities. The table below links this decision to the represented gas companies in California. It does not establish service or supplier availability for every account.
Keep a tariff change record
Record issuing utility, docket or filing reference, affected schedule, approval status, effective date and the first service period affected. Compare the approved sheet with the account’s actual classification.
Treat branding and enrollment separately
A company acquisition or a renamed program does not by itself establish a new price, automatic contract cancellation or eligibility at another utility. Retain customer notices and confirm the legal company and effective service rules.
California utility application
| Gas service company | Schedule and implementation evidence | Primary reference |
|---|---|---|
| SoCalGas | Core or noncore classification; CAT participation and the accepted agent | Official program / tariff |
| San Diego Gas & Electric | Core or noncore service and the applicable CAT eligibility category | Official program / tariff |
| PG&E | Commercial core schedule, including G-NR1 or G-NR2 where applicable | Official program / tariff |
| Long Beach Utilities | Long Beach municipal commercial gas class | Official program / tariff |
SoCalGas: the program detail behind this decision
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. Socal Cat.
Apply the evidence to an account file
Match a proposed or approved change to Core or noncore classification; CAT participation and the accepted agent. Reopen the effective company reference and confirm Who supplies, balances and bills the account; conditions for returning to utility procurement instead of importing a rule from another service company.
A change log with an explicit implementation gate
Use a row for the company, source URL, document type, schedule, status, approval date, effective date, affected accounts and action owner. A proposed sheet can inform a sensitivity scenario while remaining outside the effective budget. After approval, verify the final sheet rather than assuming the requested amount survived. For an ownership change, attach the service notice and identify any separate legacy rate areas. Retain the prior reference for earlier billing periods so corrections can be checked against the right rules.
Turn the review into a calculation
Plan notice and enrollment milestones. The planner uses your calendar-day inputs and does not send notices or confirm a utility enrollment date.
Read the California utility guide for the wider service-company distinctions. Convert billed gas units using the bill’s heat-content factor when moving from volume to energy.
