Question $6$

A power company is planning to replace a

$30-$year$-$old thermal power generator with a capacity of

$200$ MW with a new generator with a capacity of $1000$

MW$.$ They ask an engineering consultant to answer the

following questions: $($a$)$ If the cost was $$300$ million $30$

years ago and is $$1000$ million today, what is the implied

cost$-$capacity factor? $($b$)$ If the cost index $30$ years ago was

$300,$ and the cost$-$capacity factor is $0\mathrm{.}8,$ what is the implied

cost index today? $($c$)$ If the cost index has increased

by a factor of $4\mathrm{.}5,$ what is the implied cost$-$capacity

factor? Answer: $($a$)0\mathrm{.}75($b$)$ $$1087$ million $($c$)0\mathrm{.}93$
