Hello,

I would like to ask if it is possible to have multiple payment schedules, instead of just two, for a set IRR.
For example what should be the annual payments for an energy investment in order to have a set IRR for the whole investment. As the plant output decreases year after year due to derating/degredation you can not assume a fixed income as it reduces about 1% annually.

thanks,
Costas
