Five practical checks before expecting gas savings in California

California: Find which cost can actually change

Start with EIA: natural gas volume, heat content and energy units. The table below links this decision to the represented gas companies in California. It does not establish service or supplier availability for every account.

Use five separate checks

Check the billed class; reconcile readings and corrections; identify supply versus delivery; count recurring account fees; and update the consumption forecast for operational changes. Keep each proposed action tied to the charge it can affect.

Avoid counting a reduction twice

Model an equipment project at the revised gas volume before comparing supplier offers. A fixed monthly charge remains even when therms fall. Keep equipment investment, supply cost and retained utility costs in separate budget lines.

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

For this account, investigate Aggregator commodity and customer fees versus utility procurement, with delivery retained. If the proposed action changes only the supply component, retain the other components when calculating the total bill effect.

Worked check: price and volume are different effects

Assume purely hypothetical comparable commodity use falls from 10,000 to 9,000 therms while its price rises from $0.80 to $0.85 per therm. Commodity cost changes from $8,000 to $7,650. At the original price, lower volume explains negative $800; the price change on actual use adds $450. The net difference is negative $350. Fixed charges, delivery, taxes and other costs are excluded. It would be incorrect to report that entire $350 as a supplier-price saving.

Turn the review into a calculation

Compare constant supply rates and fees. Enter documented assumptions in matching energy units. Keep any charge outside both supply offers separate; the result does not establish eligibility or an available quote.

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.
