The Bt yield = 0 since last year to n. Ct = the cost of producing electricity from years 0 to. N = the age project. R = rate of interest is the opportunity cost of using the minimum loan interest rate. (1 + r) t = global options (Discount Factor) that occurred last year at t.
The yield from Bt = 0 to n = Ct cost of electricity production from 0 to n = maturity r = interest rate, the opportunity cost of capital, the minimum lending rate (1+ r) t =. The majority (Discount Factor) occurs year t.
The Bt = return since last year 0 to n Ct = cost of electricity production. Since years 0 to n = age project R = interest rate opportunity cost of capital use the minimum interest rate . (1 R) t = denominator include (Discount Factor) happened years T .
