Electricity prices are set by the marginal costs of production and electricity consumption to consumers. Each producer has set a lower power price below which they would not sell electricity. By contrast, each customer has a top of power price, above which for them are not profitable to buy and consume electricity. Basically, then is normal circumstance, when is sufficient competition in the electricity market the price describes the low price of expensive power station. Another way, then are capacity deficits situation and where competition is weak, the price of electricity characterizing consumers buying ability. So if the station is the actual energy producer, its production volume increasing will increase total power station’s profit. But, if the power station is working as an independent producer, the production minimization will increase incomes and the equilibrium price
