Get PriceThe capacity factor is the average power generated, divided by the rated peak power. Let's take a five-megawatt wind turbine. If it produces power at an average of two megawatts, then its capacity factor is 40% (2÷5 = 0.40, i.e. 40%). To calculate the average power generated, just divide the total electricity generated, by the number of hours.

Get PriceI am trying to calculate resource utilization to display weather a group is being over utilized. I know I can pull it in table view to display total hours used and total hours available but I want to be able to show it as a percentage of time used so that it readily sticks out and I can use conditional formatting to flag anything above as red.

Get PriceElectrical circuit load capacity is the total amount of power that your home actually will use. In order to decide what size electrical service is needed in your home, one has to do a little math homework. Older homes often only had a 60-amp electrical service, connected to a fuse panel.

Get PriceA 3-phase power circuit consists of three conductors of alternating current combined into a single power line. The current in each conductor is 1/3 cycle out of phase with the other two. This arrangement produces a smoother power flow and permits lower line voltages. Three-phase power circuits are commonly used in ...

Get PriceThe net capacity factor is the unitless ratio of an actual electrical energy output over a given period of time to the maximum possible electrical energy output over that period. The capacity factor is defined for any electricity producing installation, such as a fuel consuming power plant or one using renewable energy, such as wind or the sun ...
