The electricity market is a system that enables the exchange of electrical energy through an electrical grid. Historically, electricity has been sold by companies that operate electric generators and purchased by consumers or electricity retailers. Today, the market has evolved to include retail electricity markets, where end-use customers can choose their supplier from competing electricity retailers. This has introduced competition for retail electricity prices, with electric retailers offering competitive prices to acquire customers. In deregulated markets, customers have the option to select an electric supplier, while in regulated markets, customers are limited to buying power from their local utility company. The type of market and the availability of customer choice vary across regions and countries.

What You'll Learn
Deregulated markets
In the United States, the shift towards deregulation began in the 1990s when many states abandoned the traditional, vertically integrated utility markets. This change was prompted by the high cost of electricity, which was passed on to consumers by utility companies. The Federal Energy Regulatory Commission (FERC) took steps to deregulate the energy industry, leaving it to individual states to decide how to supply energy to its users.
As of 2024, more than 30 states in the US have some variation of a deregulated energy market. For example, Oregon is the only state with a solely deregulated electricity market, while 15 states have deregulated their natural gas market. It is important to note that the market is not clearly split between regulated and deregulated states, as some states, like California, have partial regulation due to the nature of the grid, historic reasons, and geographic boundaries.
In deregulated markets, the local utility company still delivers energy and maintains the infrastructure, such as power lines and gas pipelines. However, they are prohibited from generation and transmission ownership and are only responsible for distribution, operations, and maintenance. On the other hand, retail energy suppliers purchase electricity from the wholesale market and sell it to consumers, setting the prices for the "supply" portion of the electricity bill. These suppliers can offer various small business electricity options, allowing companies to choose the right type of contract and duration to fit their operations.

Wholesale electricity markets
In the past, the electricity industry was dominated by vertically integrated utilities that owned electricity generators and power lines, including distribution and transmission lines. However, many regions have moved towards deregulation, allowing for greater competition and customer choice. This transition has led to the emergence of independent energy suppliers and wholesale markets.
The structure and regulation of wholesale markets vary across regions. For example, in the United States, some states have deregulated their wholesale markets, while others have not. Regional Transmission Organizations (RTOs) and Independent System Operators (ISOs) play a crucial role in operating wholesale markets, fostering competition, and ensuring open access to transmission. RTOs and ISOs use bid-based markets to determine economic dispatch, with energy markets, capacity markets, and ancillary services markets influencing wholesale prices.
The impact of deregulation and the introduction of wholesale markets have had both positive and negative effects on electricity pricing and supply chain dynamics. On the one hand, deregulation has introduced competition, providing customers with a choice of suppliers and potentially lowering electricity bills. On the other hand, it has also led to the need for independent companies to lock customers into fixed-rate contracts, which may negatively impact customers if the agreed-upon rate becomes higher than the local utility rate. Additionally, the design of transmission networks can limit the amount of electricity that can be transmitted between areas, creating "load pockets" that need to be served with local generation.

Retail electricity markets
A retail electric market consists of utility companies, local power lines, retail energy suppliers, retail energy brokers, energy consultants, energy traders, and ultimately, energy consumers. In regulated states, utility companies are in total control of the market and dictate energy rate tariffs and consumer electricity rates. However, in deregulated energy states, markets are open to supplier competition, and consumers have the option to purchase electricity from a third-party provider, enroll in demand response programs, and even sell electricity back to the grid.
The benefits of retail electricity markets include increased competition, which can help lower consumer electric bills and allow them to tailor their energy use to their preferences, such as selecting a clean energy supplier. Additionally, consumers can fix electricity rates when prices are low or choose to float certain price components on the energy index market. Retail energy market expansion has also benefited energy companies, with many new retail electricity suppliers generating significant revenue in these markets.

Customer choice
The concept of "customer choice" in the context of electric companies refers to the ability of consumers to choose their electricity supplier, rather than being limited to purchasing from their local electric utility company. This practice is also known as "energy choice" or "retail choice".
In the United States, the electricity market has undergone significant changes over the years, with many states moving towards deregulation and allowing customer choice. As of 2022, retail choice was available in the District of Columbia and 13 states, including California, Texas, Illinois, and New York. In these deregulated areas, customers can shop for their electricity supplier, creating competition and driving down prices.
The introduction of customer choice has provided consumers with several benefits. Firstly, it enables customers to lower their electric bills by choosing suppliers with competitive pricing. Secondly, it allows customers to align their energy use with their preferences, such as selecting a clean or renewable energy supplier. Additionally, customers can choose between different types of plans, such as fixed-rate plans, variable-rate plans, or prepaid plans, depending on their needs and financial situation.
However, customer choice also presents certain challenges and considerations. For instance, independent companies often require customers to sign contracts with fixed electricity prices for multiple years, which could benefit some customers but negatively impact others if the rates end up being higher than those set by the local utility company. Additionally, customer choice typically only applies to the generation portion of a customer's utility bill, as transmission and distribution services are usually still provided by the local utility company due to their natural monopoly in those areas.

Energy trading
In the wholesale market, generating companies, electricity export/import operators, sales organizations, grid companies, and major consumers are involved in the buying and selling of electric power and capacity. Wholesale markets are subject to government policies and regulations to ensure competitiveness and protect consumers.
Spot markets, on the other hand, involve the immediate purchase and sale of electricity, allowing for real-time adjustments to meet grid demands. Within the spot market is intraday trading, which focuses on transactions within the same day. This is crucial for responding to real-time conditions and ensuring grid stability. Renewable energy producers, such as wind farms, solar farms, and hydroelectric plants, have to predict their energy production and align it with grid demands.
Energy traders play a vital role in the energy market by buying electricity from producers and selling it to energy suppliers or directly to end consumers. They analyse live generation data, news reports, and other factors like weather conditions and events to predict electricity needs during high-demand periods and determine a price.
The energy market also includes over-the-counter (OTC) trading, where power is traded directly between two parties with agreed-upon prices and volumes. Power purchase agreements (PPAs) are long-term electricity supply agreements between a power producer and a customer, providing long-term income and power provision.
