**3. General Methodology**

The following general methodology is used:


• Finally, a cost-benefit analysis is carried out to determine the economic viability of the LCS scenario in relation to the BLS scenario. Table 2 shows the fuels levelized prices assumed to be representative of fuels price evolution between 2011–2035 which were incorporated into our calculations in Excel spreadsheets as constants. Last column shows fuel's information sources. All monetary values in this study are expressed in constant year 2007 US dollars (USD).


Each phase of the methodology was simulated first in individual Excel spreadsheets, and later, energy results were exported to the Long-Range Energy Alternatives Planning System (LEAP) software [35] to obtain the aggregated energy and GHG emissions in the BLS and LCS scenarios.
