Hi Rados,

What you are looking for of course, differs between economies (or nations) and TPG technologies. However, here are some interesting leads:

These can fill you on Indian and American data. 

Since you are placed in Europe, ground level French, German, or Serbian data may be more relevant to you.

In general, the O&M calculations should take into consideration the following components:

1) Discount rates (5% and 10%).

2) Labor cost in the region of interest.

3) Frequency for maintenance.

4) Cost of components that needs replacement.

5) Downtime (loss of opportunity cost) while conducting the maintenance activities.

Here is a link to an excellent report by the National Renewable Energy Laboratory (NREL) published in 2010. The report discusses how the O&M costs are calculated.

Dear Sanjoy and Yehia,

Thanks a lot for usefull informations. It helps me a lot. Now, I have a problem to separate fuel costs for electricity and fuel costs for thermal power, because I have to calculate separate electricity cost and thermal power cost from coal-fired CHP unit. I thought that operational costs include fuel costs, but it seems that I was wrong?

Regards,

Rados

Hi Rados,

If I got your doubt correctly, then the explanation is a simple one.

What is known as running cost includes fuel cost only if the generating unit does consume fuel..

But for generators like hydro and wind, no fuel is technically required. So the fuel cost gets eliminated in such cases, and the running cost accordingly assumes a small figure.
