| Solution concept | General equilibrium (closed economy) |
| Solution method | The COFFEE model is solved through Linear Programming (LP). The TEA model is formulated as a mixed complementary problem (MCP) and is solved through Mathematical Programming System for General Equilibrium -- MPSGE within GAMS using the PATH solver. |

The electricity sector is another complex subsector within the Energy sector also assessed in COFFEE model. The transformation of primary energy and secondary energy sources into electricity includes several different options for every resource which provides the model a large number of possibilities and a better way to represent the power systems (<xr id="fig:Power"/>).

For most of the power technologies incorporated in the model, an estimation of the current installed capacity in all regions was performed. The main source of information was geo2016, except for nuclear power plants iaea2014. The COFFEE model takes a relative detailed approach for nuclear power technologies, differentiating reactor technology and, consequently, nuclear fuels. Thus, the type of nuclear fuel is depended on the nuclear reactor used. Then the costs to produce the nuclear fuels are considered and the costs relating to waste management as well. The production costs vary according to the level of enrichment (<xr id="fig:Nuclear"/>).
