A town in Wyoming wants to drill a geothermal well to provide district heating steam and hot water for its businesses and residences. After government
subsidies, the capital investment for the well is $418,000, and the geothermal well will reduce natural gas consumption for steam and hot water production by
$50,000 per year. The salvage value of the well is negligible. The simple payback period for this well is 9 years. If the MARR of the town is 6% per year and the
life of the geothermal well is 25 years, what is the IRR for this project?
Choose the closest answer below.
OA. The IRR for the project is 12.1% per year.
OB. The IRR for the project is 8.3% per year.
OC. The IRR for the project is 13% per year.
OD. The IRR for the project is 11.1% per year.
