Get PriceThe distinct ways of electricity generation can incur significantly different costs. Calculations of these costs can be made at the point of connection to a load or to the electricity grid. The cost is typically given per kilowatt-hour or megawatt-hour.It includes the initial capital, discount rate, as well as the costs of continuous operation, fuel, and maintenance.
Get PriceHowever, because the frequency-response reserve is often small and not at the discretion of the system operator it is not considered part of the operating reserve. The replacement reserve (also known as contingency reserve) is reserve power provided by generators that require a longer start-up time (typically thirty to sixty minutes).
