Many power plants can last much longer than the 20-30 years
assumed in most LCOE calculations, often 50 years or more. This
affects the LCOE estimates for solar farms, where almost the entire
LCOE is from capital costs that are multiplied by the CCF.
How much lower is the CCF for an 7% loan over a 45 year period
compared to the same loan over a 15 year period?
For example, if the 45 year period has a CCF of .06 and the 15
year period has a CCF of .1, you’d answer 40%.
