Question:

1/ A retrofit project is estimated to cost $250,000. The energy savings are expected to last 10 years. The retrofit is expect

1/ A retrofit project is estimated to cost $250,000. The energy savings are expected to last 10 years. The retrofit is expected to save 325 MWh per year. Assuming a discount rate of 6%, and an electricity cost of $0.15/kWh: a/ What is the net-present value of the system (4 marks)? b/ What is the equivalent cost of the saved energy (4 marks)?

Answers

1.

Net present value of the system=-250000+325*1000*0.15/6%*(1-1/1.06^10)

=108804.2438

2.

Annual equivalent=108804.244*6%/(1-1/1.06^10)

=14783.01044
