Question
Spring 2024 An energy efficiency project has a first cost
of $400,000, a life of 10 years, and no salvage value.
Assume that the interest rate is 10%. The most likely
value for annual savings is $50,000. The optimistic
value for annual savings is $80,000 with a probability
of 0.2. The pessimistic value is $40,000 with a
probability of 0.25. a. What is the expected annual
savings and the expected PW? b. Compute the PW for
the pessimistic, most likely, and optimistic estimates of
the annual savings. What is the expected PW?

1. An energy efficiency project has a first cost of $400,000, a life of 10 years, and no salvage value.
Assume that the interest rate is 10%. The most likely value for annual savings is $50,000. The
optimistic value for annual savings is $80,000 with a probability of 0.2. The pessimistic value is
$40,000 with a probability of 0.25.
What is the expected annual savings and the expected PW?
b. Compute the PW for the pessimistic, most likely, and optimistic estimates of the annual
savings. What is the expected PW?
