Stambios Saulės jėgainės ekonominiai aspektai

Solar’s Day In The Sun

As a startup with newer technology, Ausra faces harder financial challenges. Coal plant builders have been able to count on 80% to 90% debt at an interest rate of 5.5% to 6%. Their equity investors expect about an 11% return on equity. That puts the average cost of capital at about 7%. But since no one has built a giant solar plant, investors demand a risk premium. O’Donnell’s equity investors want a richer 20% rate of return. Plus, he can get only 50% debt, at an interest rate of 7.5%. As a result, the overall cost of capital for Ausra’s first plants is 12%.
