Facts About Natural Gas Supply

As part of our ongoing effort to provide reliable service at reasonable prices for customers, SDG&E supports a diversity of natural gas supplies.

Natural gas is the cleanest-burning fossil fuel and a preferred choice for the production of electricity that SDG&E provides. It also is used for cooking, home heating and industrial processes. To keep up with increases in demand, we support the development of new emerging natural gas resources, including supplies from the Rocky Mountains and liquefied natural gas (LNG.)

Deliveries of natural gas derived from LNG may be available locally as early as the second quarter of this year, when a new West Coast LNG terminal is scheduled to begin operations.

Research on Liquefied Natural Gas

SDG&E’s affiliated company, Southern California Gas Company, conducted a research study that was designed to assess how residential and small commercial end-use equipment responded to changes in gas quality.

During this study, laboratory tests on a variety of natural gas-fired residential and commercial equipment were conducted to evaluate safety and performance and to gather emissions data. The evaluation focused on how equipment operating characteristics changed as a function of changes in natural gas composition.
