An electricity company, or electric utility, is a company in the electric power industry that deals with the generation, transmission, distribution, and sale of electricity. Electric utilities include investor-owned, publicly owned, cooperatives, and nationalized entities, and they are regulated by local and national authorities. They are responsible for delivering electricity to homes and businesses, maintaining electrical equipment, and restoring power during outages. Electricity providers, on the other hand, are companies that purchase electricity from generators and sell it to consumers, offering various plans, rates, and customer services. In deregulated markets, consumers can choose their electricity provider, but not their utility company.

What You'll Learn
Electricity company types
Electricity companies are typically regulated by state or federal agencies, and they provide retail, wholesale, or both forms of electricity. They are responsible for the generation, transmission, and distribution of electricity, ensuring that it reaches homes and businesses.
There are several types of electricity companies, including:
- Electric Utilities: These companies manage the distribution of electricity to consumers. They are responsible for maintaining the wires, poles, and infrastructure that deliver electricity. Examples include Arab Electric Cooperative, Inc., Hawaiian Electric Light Company (HELCO), and St. Cloud Utilities.
- Water Utilities: These companies ensure a safe and reliable water supply and sewage treatment. They are similar to gas utilities, which distribute natural gas for heating and cooking.
- Transmission and Distribution Utility (TDU): This term is often used in areas with deregulated electricity markets, such as Texas. TDUs own and maintain the physical infrastructure, including power lines, poles, meters, and transformers, required to transmit and distribute electricity. They are responsible for the actual delivery of electricity and ensuring its safe and reliable transmission.
- Retail Energy Providers (REPs): REPs handle the sale and billing of electricity to consumers and provide customer service. They purchase electricity from power generators and sell it directly to customers, competing for business in deregulated markets.
- Co-ops: Co-ops provide at-cost electric services and are governed by an elected board of directors. There are two types: distribution cooperatives and generation and transmission (G&T) cooperatives. Distribution cooperatives deliver electricity to their member-owners, while G&Ts provide wholesale power to distribution co-ops. Co-ops are commonly found in rural areas without investor-owned or municipal utility options.
- Energy Services Companies (ESCOs): ESCOs focus on energy efficiency and cost reduction. They design, develop, and finance projects that save energy and reduce energy costs for their customers.
It is important to note that the specific types of electricity companies and the regulations they follow can vary depending on the geographic location and market structure.

How electricity is generated
The process of electricity generation involves converting primary sources of energy into electric power. This process occurs in power plants, which may be powered by a variety of energy sources.
Electricity is most commonly generated by power plants that use steam turbines to convert mechanical energy into electrical energy. These power plants burn fossil fuels such as coal, oil, or natural gas to heat water and produce steam. The steam then drives a turbine connected to an electric generator, which converts the mechanical energy into electricity.
Another method of electricity generation is through the use of wind turbines, which convert the kinetic energy of the wind into electrical energy. The wind turns the blades of the turbine, which spins a shaft connected to a generator, thus producing electricity.
Solar power plants use photovoltaic (PV) cells to convert sunlight directly into electricity. When sunlight hits the PV cells, electrons are knocked loose and flow through the cells, generating an electric current.
Nuclear power plants use nuclear reactions to release energy in the form of heat, which is then used to produce steam from water. The steam drives a turbine connected to an electric generator, converting the mechanical energy into electricity.
Other sources of electricity generation include hydroelectric power, which uses the force of moving water to spin turbine blades and power a generator; geothermal power, which harnesses heat from underground pools; and gas power plants, which use chemical energy to burn gas and hot air to turn turbines.

Buying and selling electricity
An electricity company, also known as an electric utility or power company, is a company in the electric power industry that deals with the generation, transmission, distribution, and sale of electricity.
The buying and selling of electricity are dependent on a range of factors, including the type of market, the role of different entities, and the impact of regulations.
Wholesale Electricity Market
Electricity markets tend to be fragmented and are managed by independent operators, including utilities companies, energy providers, and professional or institutional traders. The wholesale market involves companies that produce electricity to sell to other businesses, which then sell it to consumers. In this market, electricity cannot be stored, so demand and supply must be balanced in real-time, leading to a unique market design.
Retail Electricity Market
Retail electricity providers or energy providers buy electricity from power generators and sell it directly to consumers. They offer plans, rates, and customer service, and in some cases, handle billing and payment processing.
Impact of Regulations
The impact of regulations on buying and selling electricity is significant. In the United States, the Energy Policy Act of 1992 allowed for the deregulation of the electric utility industry in certain states. In deregulated markets, consumers have more choices, and providers compete for business by offering performance-based incentives to executives. However, regulated companies struggle to balance reasonable consumer costs with profitability to attract investors.
Power Marketers and Brokers
Companies like Enron act as power marketers, trading electricity as a commodity and managing the associated risks. They differ from brokers, who arrange transactions between buyers and sellers without taking on any risk themselves.
Technical and Financial Factors
Technical factors, such as the transmission grid and its components, influence the clearing price of electricity. Additionally, financial factors, including fuel prices, construction costs, and fixed costs, play a role in determining energy prices.
The process of buying and selling electricity involves a complex interplay between market dynamics, regulations, and the roles of various entities, all working towards meeting the energy demands of consumers.

The impact of deregulation
The deregulation of the electricity industry has had a significant impact on the way electricity companies operate and the choices available to consumers. Prior to deregulation, state-controlled utility companies were the sole energy suppliers within regional boundaries, and consumers had no choice but to pay the rates set by these companies. Deregulation has removed these restrictions, allowing for greater competition and consumer choice.
In the United States, the push for deregulation began in the 1970s in response to the energy crisis of that decade. President Jimmy Carter's five-part National Energy Act, signed into law in 1978, was a key step in this process. However, it was not until the 1980s and 1990s that states began to allow the deregulation of electricity markets. As of 2022, 17 states plus Washington, D.C., offer deregulated electricity and natural gas.
In deregulated markets, consumers can choose from a range of different providers, plans, rates, and specialized product offerings. This competition between suppliers has led to lower costs and improved services. For example, companies can develop small business energy options that respond to the unique needs of different industries. However, it is important to note that not all areas within deregulated states have energy choices, particularly in rural areas where population sparsity makes it difficult for multiple energy providers to compete.
Deregulation has also impacted the way electricity companies operate. In regulated markets, utility companies were responsible for generating, transmitting, and distributing electricity, as well as processing payments. In deregulated markets, utility companies still own and maintain the infrastructure, such as lines, wires, poles, and transformers, but they do not set the rates. Instead, they purchase electricity from power plants, either their own or from other wholesale sources, and sell it to providers at wholesale prices. These providers then sell electricity to consumers at retail prices.
Overall, deregulation has brought about significant changes in the electricity industry, providing consumers with more choices and lower costs. However, it has also introduced complexities in the market, and the full consequences of these changes are yet to be fully understood.
