Capacity factor, as many EarthTechling readers know, is a measure of how much energy a generator produces over a period of time as a percentage of the maximum it could produce. So you take the total amount of energy produced in, say, a year, and divide by the amount of power the generator would produce had it run continuously at 100 percent.
Wind power capacity factors vary considerably by site, but generally people think around 30 to 35 percent when they talk about capacity factors for wind. But in Denmark in 2013, 13 offshore wind farms, totaling installed capacity of 1,271 megawatts, together had a capacity factor of 42.7 percent.
