for life-cycle benefits are presented in Table F-5. Note that this analysis does not include
additional benefits accruing from restoring lost generating efficiency nor from increasing
efficiency beyond the original design. These benefits can be approximated by the deterministic
amount of the present value of these efficiency gains over the 50-year time horizon. This would
only be approximate since there is still a chance that unsatisfactory performance could occur after
rehabilitation. Because of the efficiency improvement, any unsatisfactory performance after
rehabilitation results in larger opportunity costs. Therefore, the risk-based opportunity costs
after rehabilitation would be larger than that shown in Table F-4.
