Electricity market is characterized by unique features that are absent in a typical commodity market.

Electricity market is by its nature difficult to store and has to be available on demand.

Diversity and sheer size of the US Electricity market made the potential trade gains large enough to justify some wholesale transactions:.

Traditional Electricity market arrangement was designed for the state of the electric industry common pre-restructuring.

Wholesale electricity market exists when competing generators offer their electricity output to retailers.

Transmission system operator in a centralized electricity market obtains the cost information for each unit of generation and makes all the decisions in the day-ahead and real-time markets.

The centralized Electricity market normally uses the LMP, and the dispatch goal is minimizing the total cost in each node.

Higher degree of centralization of the Electricity market involves the direct cost calculations by the Electricity market operator.

The Electricity market still has the central operator that exclusively controls the system in real-time, but with significantly diminished powers to intervene ahead of delivery.

System price in the day-ahead Electricity market is, in principle, determined by matching offers from generators to bids from consumers at each node to develop a classic supply and demand equilibrium price, usually on an hourly interval, and is calculated separately for subregions in which the system operator's load flow model indicates that constraints will bind transmission imports.

The consequence is that prices paid to suppliers in the "Electricity market" are substantially below the levels required to stimulate new entry.

The prices in the real-time Electricity market are determined by the LMP algorithm described above, balancing supply from available units.

Volume risk is often used to denote the phenomenon whereby electricity market participants have uncertain volumes or quantities of consumption or production.

Academic study of an earlier price cap in that Electricity market concluded that it reduced welfare, and another study said that an EU-wide price cap would risk "a never-ending spiral of higher import prices and higher subsidies".

Retail electricity market exists when end-use customers can choose their supplier from competing electricity retailers; one term used in the United States for this type of consumer choice is 'energy choice'.

The effects of a competitive retail electricity market are mixed across states, but generally appear to lower prices in states with high participation and raise prices in states that have little customer participation.

Introduction of the choice of supplier and variable pricing in the retail Electricity market was enthusiastically supported by larger consumers that can employ the time of consumption-shifting techniques to benefit from the time-of-use pricing and have access to hedging against very high prices.

Notwithstanding the favorable light in which Electricity market solutions are viewed conceptually, the "missing money" problem has to date proved intractable.
