FINAL CONSIDERATIONS
1. EXERGETIC
COSTS
→
Localization of exergy destruction main points
(energy quality degradation): both in
components and interconnections
3. ENVIRONMENTAL
COST
→
Environment unit impact in operation
[gCO2/kWh] and total [CO2] according to
external resource consumption.
2. ECONOMIC
COSTS
→
Unit cost calculation [c€/kWh] and total [€]
considering adquisition, operation and
maintenance costs.
