Which companies have the most customers?
In the United States, several companies have emerged as leaders in providing electricity services to millions of consumers nationwide. The country's electric power sector is composed of investor-owned utilities, publicly run or managed utilities, and cooperatives. Investor-owned utilities, or IOUs, are large electric distributors that issue stock owned by shareholders. In 2017, almost three-quarters of utility customers in the United States got their electricity from these companies. IOUs are most prevalent in heavily populated areas on the East and West coasts.
The two largest IOUs are in California: Pacific Gas and Electric, with 5.48 million customers, and Southern California Edison Company, with 5.07 million customers. Southern California Edison Company was the second electric utility with the highest number of customers in the United States in 2023, serving 3.7 million customers. Florida Power & Light Company, a subsidiary of NextEra Energy, was first, with 5.8 million customers. NextEra Energy is the largest energy holding company in the country and is considered one of the new energy majors due to its significant investments in renewable energy. It also has one of the highest customer satisfaction scores of investor-owned utilities in the United States.
Exelon, one of the nation's largest utility companies, serves more than 10 million customers through six fully regulated utilities. The company operates across a large urban footprint, serving major metro areas in Delaware, the District of Columbia, Illinois, Maryland, New Jersey, and Pennsylvania. NRG Energy, an American energy company headquartered in Houston, Texas, serves over 7 million retail customers in 24 US states, including Texas, Connecticut, Delaware, Illinois, Maryland, Massachusetts, New Jersey, New York, Pennsylvania, Ohio, and the District of Columbia. Duke Energy's Electric Utilities and Infrastructure business unit serves approximately 7.5 million customers in six states in the Southeast and Midwest.

How do ownership types of electric companies differ?
In 2017, the U.S. Energy Information Administration (EIA) identified almost 3,000 electric distribution companies, or utilities, in operation across the United States. The EIA categorises these utilities into three ownership types: investor-owned utilities (IOUs), publicly-owned or managed utilities, and cooperatives.
IOUs are large electric distributors that issue stock owned by shareholders. In 2017, 168 IOUs served an average of 654,600 customers each, and they served 72% of US electricity customers overall. The two largest IOUs are in California: Pacific Gas and Electric, and the Southern California Edison Company. IOUs are most prevalent in heavily populated areas on the East and West coasts.
Publicly-owned utilities, or POUs, include federal, state, and municipal-run utilities. In addition, political subdivisions may run POUs, also called public utility districts, which are utilities that residents vote into existence and which operate independently of city or country government. The United States has 1,958 POUs with an average of 12,100 electricity customers each. The largest POUs are the state-run Puerto Rico Electric Power Authority, and the Los Angeles Department of Water and Power, a municipal utility.
Cooperatives, or co-ops, are not-for-profit member-owned utilities. Co-ops are located in 47 states but are most prevalent in rural, the Midwest, and Southeast areas. Farmer co-ops began forming in the mid-1930s to bring electricity to communities not covered by IOUs or municipal utilities, and today, co-ops still serve many rural areas.

How has the number of electric companies changed over time?
The number of electric companies in the United States has evolved over time, with a diverse range of providers emerging to meet the nation's electricity needs. As of 2017, the U.S. Energy Information Administration (EIA) reported that almost 3,000 electric distribution companies, known as utilities, were in operation. These utilities fall into three main ownership types: investor-owned utilities (IOUs), publicly-run or managed utilities, and cooperatives.
Historically, the landscape of electric companies in the United States differed significantly from what it is today. In the mid-1930s, rural America lagged significantly behind urban areas in terms of electrification, with only 10% of rural homes having access to electricity. This disparity led to the enactment of the Rural Electrification Act of 1936, a federal loan program aimed at bringing electricity to rural communities. As a result, farmer cooperatives began to form, working to electrify areas that were not served by IOUs or municipal utilities.
Over the years, the ownership structure of electric companies has undergone changes due to various factors such as mergers, evolving jurisdiction boundaries, and market conditions. IOUs, while fewer in number compared to other types of utilities, tend to be the largest and serve a significant portion of customers. In 2017, IOUs served 72% of U.S. electricity customers, with almost three-quarters of customers obtaining their electricity from these companies. The two largest IOUs are in California: Pacific Gas and Electric, serving 5.48 million customers, and Southern California Edison Company, with 5.07 million customers.
Publicly-owned utilities (POUs), on the other hand, include federal, state, and municipal-run operations. In 2023, Florida Power & Light, a subsidiary of NextEra Energy, was the electric utility with the highest number of customers, serving approximately 5.8 million. Southern California Edison Company followed closely with 3.7 million customers. Cooperatives, or co-ops, are non-profit, member-owned utilities that are prevalent in 47 states, particularly in the Midwest and Southeast. They account for around one-third of electricity providers in the United States.

What are the biggest electric companies' plans for renewable energy?
Some of the biggest electric companies in the United States include Duke Energy, Exelon, Southern Company, and NRG Energy. These companies have recognized the need to transition to renewable energy sources and have taken steps to incorporate more sustainable practices into their operations.
Duke Energy, for example, has come under criticism for its involvement in the third-largest coal ash spill in American history. However, the company has expressed its commitment to sustainability and has invested in renewable energy projects. Exelon, another leading electric company, has a diverse range of energy sources, including nuclear power plants, and serves more than 10 million customers across the country.
Southern Company, a gas and electric utility holding company based in the Southern United States, serves 9 million customers in 6 states. While natural gas is not considered a renewable energy source, the company has taken steps to reduce its environmental impact by offering services that are less harmful compared to other fossil fuels.
NRG Energy, headquartered in Houston, Texas, serves over 7 million customers in 24 US states. The company has a focus on renewable energy sources and offers a range of sustainable energy solutions.
One of the most prominent renewable energy companies in the US is NextEra Energy, which is one of the largest renewable resource energy companies in the world, focusing on wind and solar power. The company has a generating capacity of about 58 GW, with 24 GW coming from fossil fuel sources, and revenues of over $18 billion in 2020.
The US government is also playing a role in the transition to renewable energy by offering funding opportunities for research and development in this sector. Domestic solar energy generation is expected to grow by 75%, and wind power generation by 11% by 2025. This shift is driven by the increasing recognition of climate change challenges and the need to reduce carbon emissions.
Overall, the biggest electric companies in the United States are gradually incorporating more renewable energy sources into their operations, whether through wind, solar, hydropower, or geothermal power. This transition is crucial to addressing the environmental and societal demands for sustainable energy solutions.
