PG&E is one of six investor-owned electric utilities in California
The Pacific Gas and Electric Company (PG&E) is one of six investor-owned electric utilities in California. It is an American investor-owned utility (IOU) and is headquartered in Oakland, 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.
PG&E is the leading subsidiary of the holding company PG&E Corporation, which has a market capitalization of $34.9 billion as of March 10, 2025. PG&E was established in 1905, from the merger and consolidation of predecessor utility companies, and by 1984 was the United States' "largest electric utility business".
The other five investor-owned electric utilities in California are PacifiCorp, Southern California Edison, San Diego Gas & Electric, Bear Valley Electric, and Liberty Utilities. These companies are also regulated by the California Public Utilities Commission (CPUC), which was created by the state Legislature in 1911.
Despite being one of six investor-owned electric utilities in California, PG&E is the largest utility in the state and covers the vast majority of Northern California. For this reason, it is often considered a monopoly, though this is not an illegal one. PG&E is also unique in that it is the only operating nuclear asset owned by an investor-owned utility in California. The Diablo Canyon Power Plant, located in Avila Beach, California, is the company's only nuclear asset and has a maximum output of 2,240 MWe.

PG&E is the leading subsidiary of PG&E Corporation
The Pacific Gas and Electric Company (PG&E) is the leading subsidiary of the holding company PG&E Corporation. PG&E Corporation has a market capitalization of $34.9 billion as of March 10, 2025. PG&E is headquartered in Oakland, California, and is one of the largest utility companies in the United States. It provides natural gas and electricity services to approximately 5.2 million households in the northern two-thirds of California, covering an area of 70,000 square miles. This area stretches from Eureka in the north to Bakersfield in the south and from the Pacific Ocean in the west to the Sierra Nevada in the east.
PG&E is regulated by the California Public Utilities Commission (CPUC), which was created by the state legislature in 1911. As of 2019, PG&E had 107,000 miles of distribution lines, with 81,000 miles of those being overhead. The company has been facing financial challenges due to its potential liabilities from multiple wildfires between 2015 and 2018, leading to bankruptcy filings in 2019. However, despite these issues, PG&E remains a significant provider of energy in California, with a long history dating back to its establishment in 1905 through the merger and consolidation of predecessor utility companies.
PG&E is not the only electric company in California, as there are other investor-owned electric utilities (IOUs) in the state. These include PacifiCorp, Southern California Edison, San Diego Gas & Electric, Bear Valley Electric, and Liberty Utilities. However, PG&E is the largest utility in the state and covers a vast majority of Northern California, making it the only choice for many residents in that region. The high cost of creating and maintaining infrastructure in the utility industry often leads to monopolies, and PG&E is considered a monopoly in Northern California.
Despite its monopoly status, PG&E is regulated and not illegal or unregulated. The company has faced scrutiny and criticism for its role in recent wildfires and other safety issues, leading to discussions of a potential state or public takeover. PG&E has pledged to make changes, including bringing in new board members and a safety monitor, to address these concerns and improve its operations in California.

PG&E's history with Californians has been bitter
The Pacific Gas and Electric Company (PG&E) is not the only electric company in California. It is one of six regulated, investor-owned electric utilities (IOUs) in the state. The other five are PacifiCorp, Southern California Edison, San Diego Gas & Electric, Bear Valley Electric, and Liberty Utilities. 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.
Additionally, PG&E has been implicated in the recent California wildfires, with investigations finding that its infrastructure was primarily responsible for causing two separate devastating wildfires in 2018 and 2018, including the Camp Fire, the deadliest wildfire in California history. The company faced potential liabilities of $30 billion from multiple wildfires between 2015 and 2018 and filed for bankruptcy protection in 2019.
The public's dissatisfaction with PG&E has led to calls for change and improved safety measures. California Governor Gavin Newsom has threatened a public takeover of the company unless it transforms into a provider of affordable, reliable, and safe energy. PG&E has pledged to make some changes, including bringing in new board members and a safety monitor. However, the company has also faced criticism for its slow progress in mitigating future risks, such as backlogged tree-trimming work.

PG&E is not the only choice for electricity in California
PG&E (Pacific Gas and Electric Company) is one of the largest utility companies in the United States. It is headquartered in Oakland, California, and provides natural gas and electricity to 5.2 million households in the northern two-thirds of California. This amounts to approximately 16 million people.
While PG&E is the state's largest utility company, it is not the only choice for electricity in California. PG&E is one of six regulated, investor-owned electric utilities (IOUs) in California. The other five are PacifiCorp, Southern California Edison, San Diego Gas & Electric, Bear Valley Electric, and Liberty Utilities.
In addition to these investor-owned utilities, some cities in California, like Alameda and Sacramento, are served by publicly-owned utilities. Community choice aggregation (CCA) programs allow customers to choose their electricity provider, with some people opting for lower costs and others seeking out green energy sources. However, even in these cases, PG&E still owns the power lines and handles the billing.
The issue of utilities regulation is complex, and utilities are often monopolies in the United States due to the high cost of creating and maintaining the necessary infrastructure. PG&E has been criticised for its role in recent wildfires and faces competition from other energy companies in the state, which are regulated by the California Public Utilities Commission (CPUC).
