As a value$-$maximizing aluminum company, should Hydro invest in wind power in light of the Utsira pilot project? Why or why not?

Larger$-$scale turbines increase the electricity more than proportionately to the increase in costs. A $1$ megawatt turine costs $$2\mathrm{.}6$ million, with the remaining equipment costs unchanged, for a total required investment of $$4\mathrm{.}1$ million to power approximately $760$ households. Electricity revenue over $15$ years rises to $$7\mathrm{.}2$ million in discounted present value. What conversion factor allows cost recovery of this larger$-$scale turbine?
