The 2019 California power shutoffs, known as public safety power shutoff (PSPS) events, were massive preemptive power shutoffs that occurred in approximately 30 counties in Northern California and several areas in Southern California from October 9 to November 1, 2019, and on November 20, 2019, by Pacific Gas and Electric Company (PG&E), Southern California Edison (SCE), and San Diego Gas & Electric (SDG&E). The power shutoffs were an attempt to prevent wildfires from being started by electrical equipment during strong and dry winds. The shutoffs initially affected around 800,000 customer accounts, or about 2.5 million people, [4] [5] [6] [ needs update ] but expanded to cause over 3 million people to lose utility-provided electrical power by late October as more utility companies from around the state also did preemptive power shutoffs.
The shutdowns have drawn widespread fierce backlash and criticism from residents as well as government officials as PG&E, SCE, SDG&E and the California Public Utilities Commission issued an apology.[ citation needed ] Many residents complained of either being misinformed or not informed when shutdowns would occur, while officials such as California governor Gavin Newsom blamed the shutdowns on PG&E's "greed and mismanagement." [7] Some people expressed their frustrations through vandalism and violence, including the egging of a PG&E office's front doors and someone shooting at a PG&E vehicle. [8]
For the state's largest utility, PG&E, to bury all of its distribution lines (relatively low voltage lines which bring power to homes, not the higher voltage transmission lines) would cost US$15,000 per customer. [9]

The "Public Safety Power Shutoff" (PSPS) has been standard practice in California for many years, though in the past, the preemptive shutoffs occurred predominantly in rural areas. PG&E warned the state for months of its impending action, set to commence when the combination of high autumn winds and dry conditions made the fires more likely to happen. [10] PG&E began its series of power blackouts in the San Francisco Bay Area on Wednesday, October 9, at around 12 AM PDT in order to reduce the risks of devastating wildfires caused by PG&E's power lines or equipment, like the October 2017 Northern California wildfires and the 2018 Camp Fire, responsible for a combined total of 95 deaths. [5] [11]
As California's population has continued to grow in suburban and exurban areas that were formerly wilderness, the risk and size of fires has escalated. More than a third of California's housing is now located in areas known as wildland–urban interface. [10] When wildfires happen upon these communities, they become more dangerous and leap from structure to structure in what is called "fast-moving urban conflagrations" that firefighters find difficult to stop. [12]
Besides safety, one of the reasons behind PG&E's (now moving into bankruptcy) imposition of the blackouts is a legal doctrine known as inverse condemnation, which makes California utilities responsible for wildfire destruction regardless of whether the utility acted negligently or not. California's interpretation of inverse condemnation is unique. The tenet is applied in other states, usually to government entities that damage private property when engaged in a public service. California's courts have ruled the principle can be applied to utilities. So the utilities are held liable for damage, even if they comply with all of California's strict energy-related rules. [13]
This policy resulted in $30B of liability for PG&E from the 2017 & 2018 fires and drove it to bankruptcy proceedings. [14] : 1 [15] : 1 In July 2019, a new $21 billion wildfire trust fund was created to pay for damages from future wildfires, started with a 50-50 balance of utility and customer monies and also reduced the liability threshold for utilities to where customers must prove negligence before companies are held liable. [15] : 1
Critics of inverse condemnation point out that it can lead to utility bankruptcies which can threaten the integrity of the California power grid as well as hurt financing the states' efforts for renewable energy and against climate change, one of the causes of the intensified fire threat. [16]
In addition to court cases in recent years and the evolution of case law which have made new standards of legal liability, the California State legislature and the Governor also enacted new statutory laws to modify the legal regime under which electrical utilities operate in California. Over 20 new wildfire-related laws were enacted in the 2019 legislative session, several of them affecting the electrical service providing utility companies. [17]
The fire risk from the electricity supply is principally from the large amount of energy carried in above-ground power lines, which under fault conditions can become a factor in the ignition of wildfires. Public utilities in the state of California have a total of 26,000 miles (42,000 km) of high voltage transmission lines, and 240,000 miles (390,000 km) of distribution lines. Distribution lines bring electricity directly to homes; two thirds of them statewide are above ground. [9] : 1 For transmission lines, the cost of constructing these underground is approximately US$80 million per mile [18] : 1 while for distribution lines, the construction cost of new underground lines is about US$3 million per mile, compared to overhead lines at about $800,000 per mile. [9] : 1
The state's largest utility, PG&E, has 107,000 miles (172,000 km) of distribution lines, 81,000 miles (130,000 km) of which are overhead. The cost to convert all of PG&E's overhead distribution lines to underground lines would be approximately US$240 billion, or roughly US$15,000 per PG&E customer. (This cost estimate is only for distribution lines, not the higher voltage transmission lines.) [9] : 1

A man dependent on an oxygen supply died 12 minutes after the outage started in his area on October 11. An investigation has been initiated. His family said he could not reach his battery-powered tank in time. [3] Large numbers of other disabled people reported issues with poor communication by PG&E of when shutoffs would occur, and with the inability to power or charge electrical devices on which their wellbeing depended during shutoffs. Affected devices included ventilators, oxygen concentrators, nebulizers, dialysis machines, refrigerators for drugs such as insulin, and electrically powered beds, hoists and wheelchairs. PG&E had a list of over 30,000 customers registered on their Medical Baseline program as being vulnerable to shutoffs, but used it only as a contact list, leaving the affected disabled customers unsupported. Dependence on the Medical Baseline list meant PG&E inevitably missing many more disabled people not registered with the program. Others who were registered reported they were not contacted. PG&E also refused to give many local counties access to the Medical Baseline list, leaving them unable to check on vulnerable residents. [29] [30]
Under backup power on October 11, 2019 [UTC], the Mission Operations Center (MOC) at the Space Sciences Laboratory at University of California, Berkeley oversaw the deployment of a satellite launched from Cape Canaveral. Paula Milano, who helps run the Laboratory, did not want to postpone the launch saying "If a scrub of the mission happens because of Berkeley, that's a huge black eye for us, and it's a huge public black eye for NASA." After notification on October 7, the lab began extensive preparation for the power outage. [31]
By late October, water had been restricted for some[ clarification needed ] in areas which rely on pump stations. [32] [ needs update ]
Sonoma–Marin Area Rail Transit commuter rail services were cancelled on October 28 [33] and 29 [34] due to loss of power at crossings throughout the system. Partial service as far north as Downtown Santa Rosa was restored the following day. [35]
After the early October power shutoffs, the CEO of PG&E stated that they found more than 100 cases of "wind-related damage" to the 25,000 miles of power lines they had de-energized. [36] [37] : 1 [23] : 1 He also stated "More than half of PG&E's 70,000-square-mile service area in Northern and Central California is considered by state officials to be at high risk of wildfire. In 2012, that designation applied to just 15% of our service area." [36]
By the end of October, PG&E officials told a federal judge that the power shutoffs so far helped prevent up to 56 wildfires; 44 from contact with vegetation and 12 cases of wind-caused equipment damage. [38]
In March 2021, the CPUC presented the results of a risk analysis study conducted by Technosylva [39] to estimate potential fire impacts that could have occurred had electric infrastructure remained energized during the Public Safety Power Shutoffs (PSPS) events managed by SDG&E, PG&E, and SCE in October 2019. [40] The risk analysis study found the following:
On October 18, 2019, PG&E announced that shutoffs could continue for 10 years before they can start to reduce significantly, which was met with scorn by many California officials. [37] [23]
Since the 2019 shutoffs, PG&E has always been continuously trying to make improvements to its electrical utilities to minimize fire risk and reduce the number of shutoffs at the same time. However, on September 5, 2020, PG&E issued a PSPS Shutoff Watch for several regions in Northern California in anticipation of scorching temperatures and gusty winds at the end of the heat wave that could easily knock off power utilities. PG&E assured customers, though, that if shutoffs do happen, they will affect fewer customers and be shorter in duration than the 2019 shutoffs, i.e. they were aiming to restore power within 12 hours of shutting it off instead of several days. [46]
A power outage is the loss of the electrical power network supply to an end user.
The Pacific Gas and Electric Company (PG&E) is an American investor-owned utility (IOU) with publicly traded stock. The company is headquartered in the Pacific Gas & Electric Building, in San Francisco, California. PG&E provides natural gas and electricity to 5.2 million households in the northern two-thirds of California, from Bakersfield and northern Santa Barbara County, almost to the Oregon and Nevada state lines.
Southern California Edison, the largest subsidiary of Edison International, is the primary electricity supply company for much of Southern California. It provides 15 million people with electricity across a service territory of approximately 50,000 square miles. However, the Los Angeles Department of Water and Power, San Diego Gas & Electric (SDG&E), Imperial Irrigation District, and some smaller municipal utilities serve substantial portions of the southern California territory. The northern part of the state is generally served by the Pacific Gas & Electric Company of San Francisco. Other investor-owned utilities (IOUs) in California include SDG&E, PacifiCorp, Bear Valley Electric, and Liberty Utilities.
The San Onofre Nuclear Generating Station (SONGS) is a permanently closed nuclear power plant located south of San Clemente, California, on the Pacific coast, in Nuclear Regulatory Commission Region IV. The plant was shut down in 2013 after replacement steam generators failed; it is currently in the process of decommissioning. The 2.2 GW of electricity supply lost when the plant shut down was replaced with 1.8 GW of new natural-gas fired power plants and 250 MW of energy storage projects.
The California Public Utilities Commission is a regulatory agency that regulates privately owned public utilities in the state of California, including electric power, telecommunications, natural gas and water companies. In addition, the CPUC regulates common carriers, including household goods movers, passenger transportation companies such as limousine services, and rail crossing safety. The CPUC has headquarters in the Civic Center district of San Francisco, and field offices in Los Angeles and Sacramento.
San Diego Gas & Electric (SDG&E) provides natural gas and electricity to San Diego County and southern Orange County in southwestern California, United States. It is owned by Sempra Energy, a Fortune 500 energy services holding company based in San Diego. The company is known for having the highest rates in the country.
Path 46, also called West of Colorado River, Arizona-California West-of-the-River Path (WOR), is a set of fourteen high voltage alternating-current transmission lines that are located in southeast California and Nevada up to the Colorado River.
Sunrise Powerlink is a high-voltage power transmission line by San Diego Gas & Electric (SDG&E) in San Diego County, California and Imperial County, California. The project was approved by the United States Forest Service (USFS) in July 2010, the U.S. Bureau of Land Management (BLM) in January 2009 and the California Public Utilities Commission (CPUC) in December 2008. SDG&E states that the 117-mile (188 km) long 230/500 kilovolt power line will bring 1000 megawatts of renewable energy from the Imperial Valley to San Diego County. The cost of the project is estimated to be $1.9 billion for construction. SDG&E, which will receive a guaranteed profit of over $1.4 billion from the construction of the line, claims that the power line is necessary to support future growth of the San Diego region, and its economic benefits to the region will measure on the order of $100 million per year. However, the project has been called one of the most controversial projects ever proposed.
The Witch Creek Fire, also known as the Witch Fire and the Witch-Guejito–Poomacha Complex Fire, was the second-largest wildfire of the 2007 California wildfire season, and the largest one of the October 2007 California wildfires. Although the Witch Creek Fire was individually smaller than the Zaca Fire of 2007, burning 197,990 acres (801 km2) acres alone, after merging with the Poomacha and McCoy Fires, the Witch–Guejito–Poomacha Complex Fire had a total burn area of 247,800 acres (1,003 km2), surpassing the Zaca Fire to become the largest complex fire of 2007. Initially igniting in Witch Creek Canyon, near Santa Ysabel, the Witch Creek Fire rapidly spread westward, fanned by powerful Santa Ana winds, and consumed large portions of San Diego County. On October 25, the Witch Fire merged with the Poomacha Fire to the north, near Palomar Mountain, before also merging with the smaller McCoy Fire on the next day. The Witch–Poomacha Complex Fire was the second-to-last fire of the 2007 October wildfires to be extinguished, with the Poomacha Fire being contained on November 13. The last remaining fire, the Harris Fire, was fully extinguished on November 16. During its duration, 80–100 feet-high flames were reported by fire officials in the Witch Fire, and the Witch Fire exhibited the characteristics of a firestorm at its height.
The 2011 Southwest blackout, also known as the Great Blackout of 2011, was a widespread power outage that affected the San Diego–Tijuana area, southern Orange County, the Imperial Valley, Mexicali Valley, and Coachella Valley, and parts of Arizona. It occurred on Thursday, September 8, 2011, beginning at about 3:38 pm PDT. It was the largest power failure in California history.
The Tubbs Fire was a wildfire in Northern California during October 2017. At the time, the Tubbs Fire was the most destructive wildfire in California history, burning parts of Napa, Sonoma, and Lake counties, inflicting its greatest losses in the city of Santa Rosa. Its destructiveness was surpassed only a year later by the Camp Fire of 2018. The Tubbs Fire was one of more than a dozen large fires that broke out in early October 2017, which were simultaneously burning in eight Northern California counties, in what was called the "Northern California firestorm." By the time of its containment on October 31, the fire was estimated to have burned 36,810 acres (149 km2); at least 22 people were believed to have been killed in Sonoma County by the fire.
The October 2017 Northern California wildfires, also known as the Northern California firestorm, North Bay Fires, and the Wine Country Fires were a series of 250 wildfires that started burning across the state of California, United States, beginning in early October. Twenty-one became major fires that burned at least 245,000 acres (99,148 ha).
The Thomas Fire was a massive wildfire that affected Ventura and Santa Barbara Counties, and one of multiple wildfires that ignited in southern California in December 2017. It burned approximately 281,893 acres before being fully contained on January 12, 2018, making it the largest wildfire in modern California history at the time. It was surpassed by the Ranch Fire, part of the Mendocino Complex, in August 2018. The fire is currently the seventh-largest wildfire in modern California history, as of 2021. The fire was officially declared out on June 1, 2018, after more than two months in which no hotspots were detected. The Thomas Fire destroyed at least 1,063 structures, while damaging 280 others; and the fire caused over $2.2 billion in damages, including $230 million in suppression costs, becoming the seventh-most destructive wildfire in state history at the time. As of August 2020, the Thomas Fire is California's tenth-most destructive wildfire. Ventura's agriculture industry suffered at least $171 million in losses due to the Thomas Fire.
The Camp Fire was the deadliest and most destructive wildfire in California's history, and the most expensive natural disaster in the world in 2018 in terms of insured losses.
The Sand Fire was a wildfire that burned in the area of Rumsey northwest of Guinda in Yolo County, California in the United States. The fire started on Saturday, June 8, 2019 at County Road 41 and Highway 16 and burned 2,512 acres (1,017 ha) as well as seven structures. The fire was fully contained as of 7:27 am on June 15, 2019. The cause of the fire remains under investigation. The fire was the first major incident of the season, in what fire officials claimed to be an indicator of the fire season to come.
The 2019 wildfire season was a fire season in California, United States. As of December 22, 2019, over 7,860 fires have been recorded according to Cal Fire and the US Forest Service, totaling an estimated of 259,823 acres of burned land. Although the 2019 fire season had been relatively quiet in California through mid-September as compared to past years, October through December was still expected to have the greatest fire potential as the Diablo and Santa Ana winds pick up.
The Kincade Fire was a wildfire that burned in Sonoma County, California in the United States. The fire started northeast of Geyserville in The Geysers on 9:24 p.m. on October 23, 2019, and subsequently burned 77,758 acres (31,468 ha) until the fire was fully contained on November 6, 2019. The fire threatened over 90,000 structures and caused widespread evacuations throughout Sonoma County, including the communities of Geyserville, Healdsburg, Windsor, and Santa Rosa. The majority of Sonoma County and parts of Lake County were under evacuation warnings and orders. Lake county only had one evacuation order and that was the town of Middletown. The fire was the largest of the 2019 California wildfire season, and also the largest wildfire recorded in Sonoma County at the time before being surpassed by the LNU Lightning Complex fires in 2020.
The Getty Fire was a 2019 wildfire that burned 745 acres (301 ha) in Brentwood, Los Angeles, California. The fire was first reported on October 28, 2019 and was contained on November 5, 2019. Thousands of people were forced to flee, 10 homes were destroyed and 15 residences were damaged.
The Maria Fire was a wildfire that burned the south of the community of Santa Paula in the area of Somis, California on the top of South Mountain in Ventura County. The fire ignited in the evening hours of Thursday, October 31, 2019 and consumed well over 4,000 acres (16 km2) within its first several hours of burning. Despite the aggressive initial attack by first responders, the fire exploded rapidly due to a strong Santa Ana wind event that was occurring in the area during its ignition.
Southern California Edison has shut off power to about 12,900 customers Thursday, Oct. 10, while an area containing almost 174,000 SCE customers is under consideration for power shutoffs as a way to prevent wildfires from starting.
The predicted Santa Ana winds initially prompted San Diego Gas & Electric to notify roughly 24,000 customers of potential power shutoffs for safety reasons, but as of 7 a.m. Friday that number had increased to just over 47,500.
We did see damage to our system because of the wind. When we patrolled all 25,000 miles of lines that we turned off, we found more than 100 confirmed cases of wind-related damage — including trees into power lines and downed power lines. Had we not shut off power, this type of damage could have sparked a fire. In fact, vegetation contacting lines was the very cause of a number of fires in the North Bay two years ago.
In an accounting to U.S. Judge William Alsup, the company said it identified 44 cases where vegetation contacted its lines and would have likely caused arcing and sparks. PG&E also identified 12 cases of wind-related equipment damage that could have caused arcing and sparks. There were 62 additional cases where PG&E identified damage that it said would not result in arcing or sparks that can trigger wildfires. The numbers are limited to the Oct, 9 shutoffs, the company said and stressed that in some cases it was not able to say whether the damage could have sparked a fire.
