Electricity spot market refers to the spot market with electric energy as the trading target, which can also be called the energy trading market. It is a power trading platform based on the principle of marketization and the relationship between supply and demand balance, which provides a bridge between power production and consumption.

After the transaction, the power can be sent directly to the corresponding consumer. The biggest feature of the power spot market is that prices have a high degree of flexibility, changes in market supply and demand will directly affect the price of electricity up and down fluctuations, which is also known as the power spot market "power market" reasons.
Electricity spot trading, simply put, is in the power trading market, can be in a specific power trading time, through the bargaining method to buy or sell electricity. Electricity spot trading market is mainly centered around the medium and long term, the day before, real-time electric energy trading and standby, frequency regulation and other auxiliary services transactions. There are two kinds of power spot trading price mechanism: one is settled according to the offer price of each market entity, and the other is settled according to the marginal clearing price of the unified price mechanism.
Electricity spot market transactions first originated in the United States.

Electricity is an energy source and a commodity, and since it is a commodity it can naturally be traded freely in the market. Spot refers to commodities that have been produced and can be "paid for with one hand and delivered with the other". If you insist on using this standard to measure, in addition to storage batteries, electric power commodities can be said to have no "spot". In the electricity market, power producers have power plants have been built and connected to the grid, with all the conditions for power generation. At this time, the power plant is actually equivalent to a "product library", stored to be sold power commodities.
Commodities produced by different types of power plants also have obvious "quality" differences, such as: "raw materials" with different carbon content, different production costs, different time periods, different production, different transmission distances, etc. (these differences and electricity in the physical function of the homogenization is not contradictory), consumers (these differences are not contradictory to the homogenization of the physical function of electricity), consumers can buy goods from different manufacturers according to their own needs. Obviously, this kind of electricity commodity available for consumers to choose is the spot in the electricity market. Therefore, electricity spot can be defined as: has been built and connected to the power grid, with the conditions of power generation plant can be expected to supply the user's power (electricity).
