Understanding gas baseline allowance and rates
Natural gas charges are separate from electric use charges on your bill. And since natural gas is a commodity, the price can vary from month to month. Learn more about natural gas charges and how they are determined.

Natural gas charges are broken down into “Gas Service”, the charge for delivery, and “Gas Energy”, the cost of the commodity. When “Gas Service” and “Gas Energy” are added together, you see your total cost for natural gas.
“Gas Service” charges show your usage broken down into baseline and non-baseline levels. Usage within the baseline allowance amount is charged at the lowest rate.
Natural Gas Rates
Delivery charges and commodity price are the two main factors that affect your costs for natural gas. The delivery charge includes the pipes, distribution system, transmission system, construction and cost of building and operating natural gas compressor stations.
The commodity price is the actual cost for natural gas and this price fluctuates monthly in response to changes in production, imports, inventories and oil prices. The California Public Utilities Commission (CPUC) regulates all rates paid by SDG&E customers.
