Segment Reporting [Abstract] |
Segment Information | SEGMENT INFORMATION We have seven separately managed reportable segments, as follows:
▪ | SDG&E provides electric service to San Diego and southern Orange counties and natural gas service to San Diego County.
▪ | SoCalGas is a natural gas distribution utility, serving customers throughout most of Southern California and part of central California.
▪ | Sempra Texas Utility holds our investment in Oncor Holdings, which owns an 80.25-percent interest in Oncor, a regulated electric transmission and distribution utility serving customers in the north-central, eastern and western parts of Texas. As we discuss in Note 5, we completed our acquisition of the investment in March 2018.
▪ | Sempra South American Utilities develops, owns and operates, or holds interests in, electric transmission, distribution and generation infrastructure in Chile and Peru. In January 2019, our board of directors approved a plan to sell our South American businesses. We expect to complete the sales process by the end of 2019.
▪ | Sempra Mexico develops, owns and operates, or holds interests in, natural gas, electric, LNG, LPG, ethane and liquid fuels infrastructure, and has marketing operations for the purchase of LNG and the purchase and sale of natural gas in Mexico.
▪ | Sempra Renewables develops, owns and operates, or holds interests in, wind and solar power generation facilities serving wholesale electricity markets in the U.S. As we discuss in Note 5, in June 2018, our board of directors approved a plan to market and sell all the segment’s wind assets and investments and solar assets and investments. In December 2018, Sempra Renewables completed the sale of all its operating solar assets, solar and battery storage development projects and one wind generation facility. In February 2019, Sempra Renewables entered into an agreement to sell its remaining wind assets and investments. We expect to complete the sale in the second quarter of 2019.
▪ | Sempra LNG & Midstream develops, owns and operates, or holds interests in, terminals for the import and export of LNG and sale of natural gas, and natural gas pipelines, storage facilities and marketing operations, all within the U.S. As we discuss in Note 5, in June 2018, our board of directors approved a plan to market and sell our natural gas storage assets at Mississippi Hub and our 90.9-percent ownership interest in Bay Gas. In February 2019, Sempra LNG & Midstream completed the sale of these assets.
We evaluate each segment’s performance based on its contribution to Sempra Energy’s reported earnings and cash flows. The California Utilities operate in essentially separate service territories, under separate regulatory frameworks and rate structures set by the CPUC. The California Utilities’ operations are based on rates set by the CPUC and the FERC. We describe the accounting policies of all of our segments in Note 1. The cost of common services shared by the business segments is assigned directly or allocated based on various cost factors, depending on the nature of the service provided. Interest income and expense is recorded on intercompany loans. The loan balances and related interest are eliminated in consolidation. The following tables show selected information by segment from our Consolidated Statements of Operations and Consolidated Balance Sheets. We provide information about our equity method investments by segment in Note 6. Amounts labeled as “All other” in the following tables consist primarily of activities of parent organizations.
