The Economics of Energy Corporations (2)

•Look at the CCGT power station model we created
•
•Assume that the capex and opex calculations remain the same
–
•Change the following assumptions:
–Capacity – 1000MW
–Gas price is $2.00/mmbtu
–Electricity price is €45/MWh
–Load factor is 80%
–Carbon price is €40/tonne
–Corporate Tax is 20%
–Efficiency is 54%
–
•For the WACC assume that the debt:equity split is 80:20, change the interest rate to 3.5% and the
Beta to 0.9
–
Homework Question

1.What is the WACC for the project?
1.
2.What is the NPV of the project, and what is the IRR? What is the payback period?
3.
3.What is the breakeven electricity price for the project?
4.
4.What is the breakeven gas price for the model?
5.
5.In one paragraph, describe the key features of the investment and whether you would recommend it
to your management
1.Remember to mention some other key assumptions

•Questions on sensitivity
–What happens if the gas price doubles?
–What electricity price is needed for the project to breakeven if the load factor falls to 20%
(assume gas price of USS$2.00/mmbtu again)
–If the carbon price doubles, what electricity price is needed to allow the project to breakeven
(load factor back to 80%)?
–If the load factor falls to 10% what capacity payment would you ask for?
