The term is "net capacity factor", which is the ratio between the expected power production to the theoretical maximum. It depends a great deal on the location, but some decent back-of-the-envelope numbers are:Robert, any idea on how new renewable plants compare to new fossil fuel plants on a likely-energy-produced basis, rather than on a possible-power basis? I would think that wind and solar has a lower GWh/yr : MW ratio than fossil fuels, which are probably lower than nuclear?
Nuclear: 90%
Coal: 70%
Gas (Combined-cycle): 80%
Gas (peaker): 20%
Wind, on-shore: 30%
Wind, off-shore: 40%
Solar: 25%
Wave: 50%
I'm quoting these off the cuff, but they give you a fair comparative sense.
