What You'll Learn

California's three biggest utility companies: Pacific Gas and Electric Co., San Diego Gas & Electric Co., and Southern California Edison
California's three biggest utility companies are Pacific Gas and Electric Co. (PG&E), San Diego Gas & Electric Co. (SDG&E), and Southern California Edison (SCE). Each of these companies has played a significant role in shaping the energy landscape of California, particularly in the southern and central regions of the state.
Pacific Gas and Electric Co. (PG&E) is one of the largest combined natural gas and electric energy companies in the world, serving more than 16 million people across a 70,000-square-mile service area in Northern and Central California. PG&E has a long history in California, dating back to the late 19th and early 20th centuries, when it was involved in the development of gas-lit street lamps and the electrification of streetcar systems. Today, PG&E offers various programs to support its customers, such as the Family Electric Rate Assistance (FERA) program, which provides an 18% discount for eligible households.
San Diego Gas & Electric Co. (SDG&E) has been providing energy services to the San Diego region since the early 20th century. The company was formed in 1881 as the San Diego Gas Company, supplying gas for the city's street lamps. Over time, it expanded its services, and by 1920, it was providing gas and electric services to San Diego and the surrounding areas, including Orange County and towns near the Mexican border. SDG&E has been instrumental in the region's economic growth, with the construction of power plants like the South Bay power plant, which began operations in 1960.
Southern California Edison (SCE), based in Rosemead, California, serves a large portion of Southern California, excluding most of the city of Los Angeles and the desert regions. SCE has a diverse energy portfolio, including conventional and renewable sources, and is committed to providing safe, reliable, and affordable energy to its customers. The company has made significant investments in new equipment and distribution systems to meet the region's growing energy demands.
Together, these three utility companies have helped power California's economy and communities, providing essential energy infrastructure and services to millions of residents and businesses across the state. They continue to play a pivotal role in shaping California's energy future, adapting to new technologies, and addressing the challenges of a changing energy landscape.

Electric Load-Serving Entities (LSEs)
In California, there are several LSEs, including Investor-Owned Utilities (IOUs) and Publicly Owned LSEs, which include Publicly Owned Utilities (POUs). Examples of IOUs are Bear Valley Electric Service (BVES) and Liberty Utilities, while POUs include Alameda Municipal Power and Anaheim, City of Public Utilities Department.
LSEs in California also include municipal utility districts, such as the Sacramento Municipal Utility District (SMUD) and the Truckee Donner Public Utilities District. There are also electric utility departments within city governments, such as Redding Electric Utility and Riverside, City of Public Utilities Department.
Additionally, there are electric cooperatives, such as Anza Electric Cooperative, Inc., and Plumas-Sierra Rural Electric Cooperative. These cooperatives are owned and operated by their members, providing electricity to their communities.
The role of LSEs is crucial in ensuring a stable and reliable supply of electricity to customers in California. They are responsible for managing demand, procuring electricity, and maintaining the distribution system to guarantee reliable service to their customers.

Community Choice Aggregation (CCA) electricity providers
California has a diverse range of electric providers, including investor-owned utilities, municipal utilities, and community choice aggregators (CCAs). CCAs are locally controlled and give residents and businesses the ability to choose renewable sources of electricity, often at a lower cost than the state's three major utility companies: Pacific Gas and Electric Co., San Diego Gas & Electric Co., and Southern California Edison.
CCAs are local not-for-profit programs that empower communities to purchase electricity collectively on behalf of residents and businesses, instead of relying solely on investor-owned utilities. This model fosters competition in the electricity market and promotes renewable energy adoption. CCAs are particularly attractive due to their potential for lower electricity prices, resulting from the collective buying power of entire communities. Customers can also expect the same delivery and maintenance services from their local utility provider, ensuring convenience and reliability.
The California Community Choice Association (CalCCA) represents the interests of operational CCA providers at the California Legislature, advocating for their long-term sustainability. As of 2024, there are 25 operational CCA programs serving over 14 million customers across California, with more in development. This includes CCAs like Pioneer in Placer County, RCEA in Humboldt County, and San Jose Clean Energy, each working to increase renewable energy usage and community investment.
CCAs are authorized by local governments, and participation is voluntary, with opt-out or opt-in provisions depending on the specific CCA. Customers who do not opt out are automatically enrolled in the program, ensuring broad participation. CCAs also offer tiered structures, allowing customers to choose a "greener" option at a premium or a standard plan.
The success and growth of CCAs in California demonstrate the state's commitment to embracing a clean energy future, providing consumers with more choices, and driving economic development through locally controlled energy initiatives.

Public Power in California
California's electricity sector is a mix of publicly and privately owned companies. The state's three major private utility companies are Pacific Gas and Electric Co. (PG&E), San Diego Gas & Electric Co., and Southern California Edison. However, there is also a strong presence of public power entities in the state.
The SCPPA, on the other hand, is a joint powers authority comprising ten municipal utilities and one irrigation district in Southern California. SCPPA was formed in 1980 to help finance the acquisition of generation and transmission resources for its members. The SCPPA includes municipal utilities from cities such as Anaheim, Burbank, Los Angeles, and Riverside. In 2016, SCPPA was ranked as the 14th largest public power system in the United States by net generation.
In addition to these larger entities, California also has numerous local public power providers. These include the City of Palo Alto Utilities (CPAU), which operates a wide range of utility services, and Ukiah Public Utilities, which is Mendocino County's only customer-owned utility provider. Other public power entities in California include Gridley Electric Utility, Healdsburg Electric Utility Department, Lodi Electric Utility, and Redding Electric Utility, among others.
The state also has Community Choice Aggregators (CCAs) or Community Choice Energy programs, which are locally controlled and give residents and businesses the ability to choose greener, renewable sources of electricity at competitive rates. CCAs are nonprofit local agencies that can offer better deals by managing their portfolios efficiently and keeping operating costs low.
