An energy efficiency project has a first cost of exist400,000, a life of 10 years, and no salvage value. Assume that the interest rate is 8%. The most likely value for annual savings is exist60,000. The optimistic value for annual savings is exist80,000 with a probability of 0.3. The pessimistic value is exist40,000 with a probability of 0.2. What is the expected PW of this project? exist1312 exist16, 025 -exist5675 exist2604
