Assume a CO2 emissions price at 30€/t and uniform discount rate of 4%. a) Compute and plot the full cost curve in €/KW for the above technologies (for simplicity compute values of full cost for 0 to 8760 hours of operation, by a step of 500 hours). b) Compute the respective hours at the cost intersection break points of the above cost curves, and the respective €/KW cost of technologies at these break points.
