Hi

I read more about IRR...

EHR didn't tell us the payback period (which is most important, because it base on ROE %)

while IRR can be very bias with long period.

for example, if you have one investment cost 10bil, with 1m profit, you can still get 90% IRR with 1000 years (or 10,000 years).

anyway, it is easy to calculate payback period:

Payback Period for "Copahue Project"
Cost= 134mil
Year 1 = 15 mil (total=15m)
year 2 = 15 mil (total=30m)
year 3 = 15
...
year 8 = 15 (total 120)
year 9 = 15 (135)

so pay back period = 9 year (assume electric price stay same)
