The cost of each energy source (Brazil)

The cost of each energy source (Brazil)

Using data from the National System Operator (ONS)  I built the above table

  • Energy column

    It is the power production of the source  
  • Capacity column 

    It is the installed nominal capacity of the source 

  • It is the energy produced referred to the nominal capacity of the source 

Currently the unitary investment in $/kW installed is roughly the same in order of magnitude for all energy sources!

This means that for the sake of costs, the most economical alternative is one that offers a higher % (right column) because in financial terms, the same amount invested will have a lower amortization component.

This analysis does not take into consideration the wire fees (tariffs granted by ANEEL) which are way lower than generation costs. So for this simplified initial approach it is consistent!

PS Thermal plants must have the fuel cost considered. The table only shows the capacity cost
