Comparing costs
• Comparing total costs of each technology forcovering each slice• Slice 1: 2500 MW, 8760 h.
• N: 656,4 M€• FC = 210 * 2 500 000 = 525 M€• VC = 6 * 2 500 * 8760 = 131,4 M€
• C: 679,2 M€• FC = 114 * 2 500 000 = 285 M€• VC = 18 * 2 500 * 8760 = 394,2 M€
• F: 837 M€• FC = 72 * 2 500 000 = 180 M€• VC = 30 * 2 500 * 8760 = 657 M€

Analytical comparison
• T1 substitutes T2 if:FC1 + VC 1 * h FC2 + VC 2 * h
h (FC1 - FC2) / (VC 2 - VC 1) = h*
Then, T1 substitutes T2 if the running hours are greater
than h*.
• N vs. C:
• h* = (210 000 – 114 000) / (18 - 6) = 8000 h
• C vs. F:• h* = (114 000 – 72 000) / (30 - 18) = 3500 h

• How to include in the study the NSE (non-servedenergy) cost?• The maximum price the demand is willing to pay for the
electricity
• Consider a non-served energy cost of 80 €/MWh
• How would the solution change if…• …we change the rate of return of the project
• …we introduce a price for CO2 (provided technologyspecific emission rates)

The basic centralized contextOptimal thermal mix (with pre-existing hydro)
• Let us reconsider the previous problem of determininig the optimal mix
• But now we have in the system (before installingthe thermal generation) a hydro plant (theinvestment has alrealdy been done)• Maximum power output: 500 MW
• The size of the reservoir is 1500 GWh
• Which is the optimal mix now?• What is it more economical when considering the
investment costs? • Dispatching the hydro in the peak or as a base load?
