Electricity retailing, or the final sale of electricity from generation to the end-use consumer, has evolved since its inception in the late 19th century. Initially, electricity was generated by companies for their own use, but they eventually began selling it to third parties. The basic principle of supply has largely remained the same, with electricity meters measuring consumption and determining charges. However, the electricity market has undergone significant changes, particularly with the deregulation that began in the 1990s, opening up competition among suppliers. Today, electricity retailers play a crucial role in managing risk and offering fixed or variable prices to their customers, while also providing options for green power sourced from renewable energy. The deregulated market has brought both benefits and challenges, with customers gaining more choices and control over costs, but also facing potential drawbacks, such as the California electricity crisis in 2001, which highlighted the importance of effective risk management and market regulation.

Retail electricity markets vary across locations, with some offering limited competition
Retail electricity markets have evolved since the onset of energy deregulation in the US, with many new retail electricity suppliers entering the market. The basic principle of electricity retailing has remained the same: the final sale of electricity from generation to the end-use consumer. However, the market structure has changed, with the introduction of competition and consumer choice.
The retail electricity market consists of utility companies, local power lines, retail energy suppliers, retail energy brokers, energy consultants, energy traders, and ultimately energy consumers. In some markets, retail competition is limited to certain segments, such as large commercial and industrial customers. In other markets, retail competition is open to all end-use consumers.
The benefits of retail competition and consumer choice are well-documented. Consumers can save money by choosing from competing suppliers, and they can also opt for "green" power, i.e. electricity sourced from renewable energy. Additionally, companies such as solar developers and distributed energy resource suppliers benefit from open market access and can easily interface with utilities to provide services to end users.
However, the transition to a competitive market has not been without challenges. In some markets, utilities still enjoy a monopoly or duopoly and use their political influence to block or delay initiatives that would introduce competition. Additionally, independent companies may require customers to sign long-term contracts, locking them into a set electricity price that may end up being more expensive than the regulated rate.

Retail electricity suppliers purchase and resell energy, offering fixed or variable prices
Retail electricity suppliers purchase energy from the wholesale market and resell it to consumers, offering fixed or variable prices. The wholesale electricity market is a system that enables purchases through bids to buy and sales through offers to sell, with prices set by supply and demand principles. Retail electricity suppliers then re-price the electricity and take it to market.
In the wholesale market, generators sell power to load-serving entities, which then sell it to consumers. This structure ensures that the investment risk falls on the electric suppliers rather than the customers. Retail electricity suppliers are required to support enough generating capacity to meet the forecasted load, and they manage the risk involved in purchasing electricity from spot markets or electricity pools.
The deregulation of electricity markets has introduced competition, allowing customers to choose their supplier and creating a market for retail electricity suppliers. Previously, utility monopolies controlled the power supply chain, and the local monopoly supplier managed the connection, disconnection, and billing of electricity consumers. Now, in restructured markets, customers can choose their supplier, and in some cases, their generation supplier directly.
Retail electricity markets vary from one location to another, and even within a state or province. In some places, retail competition is limited to certain segments, such as large commercial and industrial customers, while in other areas, all end-use consumers can choose their supplier. The introduction of supplier choice and variable pricing has been supported by larger consumers, who can employ consumption-shifting techniques to benefit from time-of-use pricing and hedge against high prices.
Fixed-rate contracts with generation suppliers can offer customers a set electricity price for multiple years, which may be beneficial for some but could negatively impact others if the rate becomes more expensive than the local utility's rate. Retail electricity suppliers offering fixed prices must manage the risk of purchasing electricity at high spot prices, as seen in the 2001 California electricity crisis, where suppliers had to buy at high spot prices and sell at low fixed rates.

Deregulation has allowed new suppliers to enter markets, generating billions in revenue
Deregulation has transformed electricity markets, allowing new suppliers to enter and generate substantial revenue. Prior to the 1990s, most electricity utilities were vertically integrated monopolies, controlling the entire supply chain. However, many countries, including the UK, and the US, deregulated their electricity markets, opening them up to competition. This move has had a significant impact on the industry.
In a deregulated market, participants have more freedom to trade with one another, and there are often more participants at each stage of the supply chain. This increased competition benefits consumers by giving them more control over their electricity bills and allowing them to choose a supplier that meets their needs. It also encourages innovation and efficiency as suppliers compete for customers. For example, a 2016 study found that consumers in deregulated markets saved an average of 12% on their electric bills.
Deregulation has particularly benefited energy companies, with many new suppliers entering the market and generating billions of dollars in revenue. These suppliers can now market themselves directly to homes and businesses, offering fixed or variable pricing options. The open market access also benefits other companies, such as solar developers and distributed energy resource suppliers, who can now interface more easily with utilities and provide services to end users.
However, deregulation has not been without its challenges. In a deregulated market, utilities remain responsible for the delivery and maintenance of electricity, and the basic structure of the power market remains the same. Additionally, independent companies may require customers to sign long-term contracts, which can lock them into set electricity prices. Poor risk management and market regulation can also lead to issues, as seen in the 2001 California energy crisis.
Overall, deregulation has allowed new suppliers to enter electricity markets and generate significant revenue, creating a more dynamic and competitive industry.

Customers can choose their supplier, with some states offering a default service provider
Electricity retailing is the final sale of electricity from generation to the end-use consumer. In the past, electricity retailing consisted of managing the connection, disconnection, and billing of electricity consumers by the local monopoly supplier. In many utilities, there was a marketing function that encouraged electricity usage when there was excess capacity and discouraged it when there was a shortage.
In 1990, the electricity market was deregulated in many countries, including the United Kingdom, opening up the supply of electricity to competition. This trend continued in other countries, and the role of electricity retailing changed from an administrative function to one that involves advising users about switching suppliers.
In the United States, the restructuring of the electricity market has allowed customers to choose their electricity supplier in some states. As of 2022, retail choice was available for all utility customers served by IOUs (investor-owned utilities) in the District of Columbia and 13 states, including California, Connecticut, Delaware, and Illinois. These states have implemented community choice aggregator (CCA) programs that utility customers can opt into or out of. In Texas, all customers connected to the electric grid managed by the Electric Reliability Council of Texas (ERCOT) must choose an electricity provider. Additionally, six states, including Michigan and Nevada, offer non-residential utility customer retail choice.
The availability of retail choice has empowered consumers to choose the source of their electricity and has led to the development of public benefit programs that promote renewable energy and energy efficiency. Customers can now select from various supply options, including standardized retail products and customized project-specific products, to meet their unique financial and environmental objectives. Retail Renewable Energy Certificates (RECs) are also available for purchase separately from electricity, allowing customers to support renewable energy projects.
The expansion of the retail energy market has benefited energy companies, with some top retailers generating billions of dollars in revenue. However, the lack of retail choice in some areas is due to the political influence of incumbent utilities, which enjoy a monopoly or duopoly and use their lobbying power to block initiatives that promote competition.

Retail electricity markets are shaping the US energy economy, with RTOs managing wholesale markets
Retail electricity markets are an integral part of the US energy economy, with RTOs (Regional Transmission Organizations) managing wholesale markets. The basic principle of electricity retailing has remained unchanged since its inception in the late 19th century, when electricity was first made available to the public for street lighting and trams. The public could purchase electricity once large-scale electric companies were established, and the provision of these services was the responsibility of electric companies or municipal authorities.
Electricity retailing is the final sale of electricity from generation to the end-use consumer and is the fourth major step in the electricity delivery process, which also includes generation, transmission, and distribution. Retail electricity markets can vary significantly from one location to another, even within a state or province. In some places, retail competition is limited to specific market segments, such as large commercial and industrial customers. In contrast, other locations have open competition for all end-use consumers.
The formation of retail and wholesale electric markets has shifted control away from utility monopolies. Customers in restructured markets can now choose their electricity suppliers, promoting competition and giving rise to retail energy suppliers. These suppliers purchase and resell energy, and energy brokers advise customers on selecting the best supplier rates. The introduction of supplier choice and variable pricing in the retail market has been well-received by larger consumers, who can employ consumption-shifting techniques to benefit from time-of-use pricing and hedge against high prices.
RTOs have replaced utilities as grid operators and are responsible for managing wholesale electricity markets and overseeing grid operations. Wholesale energy prices are set by the ISO (Independent System Operator) and RTO markets, with federal oversight. RTOs account for transmission congestion by allowing prices to differ by location, resulting in higher prices in areas with high demand and scarce electric resources. They also use ancillary services markets to reward attributes not covered in energy or capacity markets, such as functions that maintain grid frequency and provide short-term backup power.
