The price of electricity is influenced by several factors, including fuel prices, power plant costs, weather conditions, and government regulations. In the United States, the Federal Energy Regulatory Commission (FERC) plays a crucial role in regulating electricity markets, particularly in wholesale electricity sales between power suppliers and utilities. FERC oversees organized markets and ensures fair practices through proceedings that address market rules and unjust rates. On the other hand, retail electricity prices, which are usually highest for residential and commercial consumers, are overseen by state and local regulators. The dynamic between regulated and deregulated markets varies across states, with some states adopting partial deregulation. Legislative initiatives and environmental regulations also impact electricity prices, with a shift towards cost-competitive renewable energy technologies.

What You'll Learn
Federal and state government initiatives
In the 1990s, many states opted to deregulate their electricity systems, intending to introduce competition and reduce costs. This restructuring led to the emergence of independent energy suppliers. However, some states, such as New York, have delayed or suspended these plans due to concerns about the potential negative impact on end-use consumers. The Federal Energy Regulatory Commission (FERC) oversees wholesale or bulk transactions, while retail sales are regulated by individual states. FERC's general policy has been to expand market roles and reduce direct regulation.
State regulators play a crucial role in ensuring reasonable electricity rates for customers. They oversee how electric utilities set prices, considering operating and investment costs, along with a "fair" rate of return. This revenue requirement must be approved by the state's public utilities commission to prevent overcharging. Additionally, regulated utilities need state approval for power plant investments, which are assessed through an Integrated Resource Planning (IRP) process that ensures investments are necessary and aligned with meeting customer demand.
Federal and state legislative initiatives have also promoted the development of cost-competitive renewable energy technologies. For example, New York and Illinois adopted proposals allowing nuclear facilities to earn Zero Emission Credits (ZECs), encouraging the use of emissions-free energy. Furthermore, legislative proposals and environmental regulations are likely to increase costs for energy consumers as they impose additional costs on electricity generators using carbon-rich fossil fuels.

Electricity prices and fuel prices
Electricity prices are influenced by several factors, including the cost of building, financing, maintaining, and operating power plants and the electricity grid. Fuel prices are a significant contributor to electricity prices, especially for natural gas and petroleum fuels. Extreme weather conditions can also impact electricity demand and prices, as can the availability of power plants and fuels, local fuel costs, and pricing regulations.
In the United States, electricity markets are regulated at both the federal and state levels. The Federal Energy Regulatory Commission (FERC) has jurisdiction over wholesale electricity sales between power suppliers and utilities, and it oversees organized markets for these transactions. FERC also regulates Regional Transmission Organizations (RTOs) and Independent System Operators (ISOs), which manage day-to-day electricity transmission and wholesale markets. However, FERC does not have authority over retail electricity purchases, which are overseen by state and local regulators.
Some states have opted for deregulation, allowing market forces to determine electricity prices. In contrast, others maintain traditional rate regulation, where state regulators oversee how utilities set electricity prices to keep rates reasonable for customers. The choice between deregulation and rate regulation can impact price trends, with regulated states experiencing slightly higher percentage increases in prices over time.
Fuel prices are influenced by various factors, including supply and demand, production and exploration costs, competition, and market speculation. Fuel prices can fluctuate due to extreme weather events, production disruptions, and changes in exploration and production costs. Additionally, government regulations and initiatives, such as those promoting renewable energy technologies, can impact fuel prices.
In summary, electricity prices and fuel prices are interconnected, with fuel costs being a significant component of electricity generation costs. The regulation of electricity markets and the choice between deregulation and rate regulation can influence price trends and fluctuations. Fuel prices, in turn, are subject to various market and external factors, which can lead to price volatility.

Wholesale and retail electricity markets
Wholesale electricity markets refer to sales of electricity between power suppliers and utilities. Wholesale markets are subject to regulation by the Federal Energy Regulatory Commission (FERC), which has oversight over wholesale power transactions on the two large, interconnected grids: the eastern and western interconnects. FERC also regulates RTOs/ISOs (Regional Transmission Organizations/Independent System Operators) via electricity market proceedings.
RTOs/ISOs manage the day-to-day electricity transmission needs for millions of people, plan for the long-term needs of the electric power system in their areas, and run the wholesale electricity markets. For example, the California Independent System Operator (CAISO) operates a competitive wholesale electricity market and manages the reliability of its transmission grid across California and a portion of Nevada.
In wholesale markets, generators sell power to load-serving entities, which then sell it to consumers. Wholesale physical power trade typically occurs through bilateral transactions, where power plants bid to provide electricity at a given price. The RTO/ISO will then call on the lowest bidder to produce the necessary power.
Retail electricity markets refer to the electricity purchases made by consumers, overseen by state and local regulators. Retail rates in regulated states are based on a regulated rate of return on investments, while in deregulated states, utilities purchase electricity at market-determined wholesale prices and then sell it to customers at market-determined retail prices.
Increases in retail electric prices from 1997 to 2021 were about half a cent more in states with deregulated electric markets than in regulated states. However, since 2012, residential rates in deregulated states have increased by 2.5 cents, compared to a 1.4 cent increase in regulated states.

Independent companies and fixed rates
In the US, the Federal Energy Regulatory Commission (FERC) has jurisdiction over sales of electricity between power suppliers and utilities, which are known as "wholesale sales". FERC also has oversight over organised markets for wholesale electricity sales. However, FERC does not regulate retail electricity purchases, which are overseen by state and local regulators.
In the 1990s, many US states decided to deregulate their electricity systems to create competition and lower costs. This transition, known as restructuring, required electric utilities to sell their generating assets, leading to the emergence of independent energy suppliers. As a result, electricity customers in deregulated areas gained the option to choose their electric supplier, rather than being limited to purchasing electricity from their local utility company.
Independent companies often require customers to sign contracts, locking them into a set electricity price for multiple years. While fixed rates can provide customers with price stability and flexibility, they also carry the risk of being locked into a contract that is more expensive than the variable rates set by the local utility. Additionally, customers on fixed-rate plans may end up paying more during market declines.
Fixed-rate electricity plans offer protection against rate fluctuations during high-demand periods. These contracts usually last between 12 and 36 months and can be terminated early if needed. However, it is important to note that fixed-rate plans may include hidden costs, as energy suppliers charge a premium to offer these stable pricing structures. The largest users of electricity tend to unbundle their electricity supply to avoid rate premiums from energy suppliers.

Transmission and distribution services
The Federal Energy Regulatory Commission (FERC) oversees wholesale or bulk transactions that occur before state-jurisdictional retail sales. FERC has jurisdiction over sales of electricity between power suppliers and utilities, known as wholesale sales, and the markets for these sales. However, FERC does not regulate the rates, terms, and conditions for the distribution of electricity; these are typically regulated by state or local agencies. The exception to this is the transmission charges included in retail rates, which FERC approves.
In the 1990s, many US states deregulated their electricity systems to foster competition and lower costs. This led to the creation of independent energy suppliers. However, due to the high costs of creating their own power line infrastructure, electric utilities retained their transmission and distribution assets and became transmission and distribution utilities, which remain regulated.
The electricity transmission and distribution systems incur construction, operation, and maintenance costs. These costs include repairing damage caused by accidents or extreme weather events and improving cybersecurity. The rates for transmission services are determined through formula rates, which are designed to ensure transparency and allow customers and other interested parties to seek detailed information and challenge the utility's calculation.
