Your power plant on Gilligans Island is producing too much air pollution. The professor gives you three choices for dealing with this problem:

You can pay a pollution tax (Carbon Offsets) onetime of $13,000,000 immediately.

You can close the plant and install a power cable from the mainland to the Island. That will cost you $1,000,000 at the end of this year, $3,000,000 at the end of next year and then $750,000 forever for maintenance.

You can retrofit the plant with scrubbers to reduce the emissions to make the plant green. That will cost $7.5m at the end of this year and $100,000 for 50-years for maintenance.

Assume that the cost of generating power on the mainland is approximately the same as the cost of generating power at your Gilligans Island plant. Assume, this comes as a surprise to you and you have not saved any money in reserves and you need to raise capital. Additional information is that market has a 12 percent market risk premium on the power plant with the risk free rate being 5 percent with a company tax rate of 35 percent.

Current total raised capital at the power plant: (This will help you calculate the WACC)
