Commitments and Contingencies Disclosure [Abstract]

Schedule of Environmental Remediation Liability

The Utility’s environmental remediation liability is primarily included in Noncurrent liabilities on the Consolidated Balance Sheets and is comprised of the following:

	Balance at
(in millions)	December 31, 2025		December 31, 2024
Topock natural gas compressor station	$	315	$	294
Hinkley natural gas compressor station	99		97
Former MGP sites owned by the Utility or third parties (1)	715		782
Utility-owned generation facilities (other than fossil fuel-fired), other facilities, and third-party disposal sites (2)	71		76
Fossil fuel-fired generation facilities and sites (3)	17		18
Total environmental remediation liability	$	1,217	$	1,267

(1) Primarily driven by the following sites: San Francisco Beach Street, San Francisco Outside East Harbor, San Francisco East Harbor, San Francisco North Beach and San Francisco Fillmore Street.

(2) Primarily driven by Geothermal Landfill and Shell Pond site.

(3) Primarily driven by the San Francisco Potrero Power Plant.

The table below presents the high end of the range for the Utility's potential losses and whether HSMA recovery is available.

	Balance at December 31, 2025
(in millions)	Low end of the range		High end of the range		HSMA Recovery (1)
Topock natural gas compressor station (2)	$	315	$	518	Available
Hinkley natural gas compressor station (2)	99		221		Unavailable
Former MGP sites owned by the Utility or third parties (3)	715		1,292		Available
Utility-owned generation facilities (other than fossil fuel-fired), other facilities, and third-party disposal sites (4)	71		146		Available
Fossil fuel-fired generation facilities and sites (5)	17		32		Unavailable

(1) For sites where HSMA recovery is available, the Utility expects to recover 90% of the costs associated with environmental remediation through rates.

(2) The Utility is legally responsible for remediating groundwater contamination caused by hexavalent chromium used in the past at the Utility’s natural gas compressor stations. The Utility is also required to take measures to abate the effects of the contamination on the environment. At the Topock site, the Utility completed the initial phase of construction on an in-situ groundwater treatment system in 2021, and additional construction will continue for several years.

(3) Former MGPs used coal and oil to produce gas for use by the Utility’s customers before natural gas became available. The by-products and residues of this process were often disposed of at the MGPs themselves. The Utility has a program to manage the residues left behind as a result of the manufacturing process; many of the sites in the program have been addressed.

(4) Utility-owned generation facilities and third-party disposal sites often involve long-term remediation.

(5) The Utility sold its fossil-fueled generation power plants in 1998 but retains the environmental remediation liability associated with each site.
