Electric power is the rate at which an electric circuit transmits electrical energy per unit of time. The watt, or one joule per second, is the SI unit of power.

Electric generators are the most common source of electricity. However, other sources such as electric batteries can also be used. The electric power sector often provides it to companies and residences (as residential mains electricity) via an electric power grid.

Transmission lines can transport electric power across vast distances and be utilized for high-efficiency applications, including motion, light, and heat.

Electric power is widely employed in industrial, commercial, and consumer applications because it is generated at central generating stations and delivered through an electrical transmission grid. A country’s per capita electric power consumption is linked to its industrial growth. Electric motors are used to propel subways and railway trains, as well as to power manufacturing machines. The most common type of artificial light is electric lighting.

Electrical energy is directly employed in operations such as the extraction of aluminum from its ores and the manufacture of steel in electric arc furnaces. Telecommunications and broadcasting require consistent electric power. In hot regions, electric power is utilized to provide air conditioning, and in some areas, electric power is a cost-effective energy source for building space heating. Individual residential wells to irrigation operations and energy storage projects all require electric power to pump water.

Industry of electric power

Electric power generation, transmission, distribution, and sale to the general public and industry are all covered under the electric power industry. When electricity was first generated for electric lights in 1882, commercial distribution of electric power began. Growing economic and safety concerns led to industrial regulation in the 1880s and 1890s.

What was once an expensive novelty restricted to the most densely populated places, dependable and affordable electric power has become a necessary component of the routine operation of all parts of modern economies.


Electricity was seen as a “natural monopoly” by the middle of the twentieth century, only efficient if a small number of companies participated in the market. In some areas, vertically integrated companies provided all stages from generation to retail, and only governmental supervision regulated the rate of return and cost structure.

Many areas have split up the generation and distribution of electric electricity since the 1990s. While such markets can be abused, resulting in negative customer pricing and reliability impacts, competitive electrical energy generation typically leads to meaningful efficiency gains. Transmission and distribution, on the other hand, are more difficult challenges to solve since returns on investment are harder to come through.

The electric power business is often divided into four stages. Energy generating, such as a power plant, electric power transmission, electricity distribution, and electricity retailing, are examples of these services. Electric power corporations own the whole infrastructure in many nations, from producing stations to transmission and distribution.

As a result, electric power is considered a natural monopoly. The industry is tightly controlled, typically with price controls, and is frequently owned and administered by the government. In at least the latter two processes, however, the current tendency has been increasing deregulation.

The type and state of market reform in the energy market frequently decide whether electric firms may participate in only parts of these activities without owning the complete infrastructure or whether citizens select which infrastructure components to patronize. End-users of energy may choose more expensive green electricity in nations where electricity is deregulated.

There are advantages and disadvantages to all types of power generating. Although technology will most likely determine the most favored forms, the alternatives with the lowest prices will typically be picked above other sources in a market economy. It is still unclear whether form or method would best satisfy the essential energy demands or address the power demand. Renewable energy appears to be fast becoming the most economically viable option. Electricity price spikes are less likely when there is a broad mix of power sources.
