    Institution COPPE/UFRJ (Cenergia), Brazil,
    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 transformation of energy forms, i.e., from primary energy to secondary and, eventually, final energy is detailly represented in the COFFEE model. The chosen technology to meet the energy service demand is subject to the many economical and technical features that characterize the energy conversion technologies, as listed below:

    • All technologies considered
    • All elements that characterize the technologies
    • Investment costs
    • Maintenance costs
    • Variable operation costs
    • Fixed costs
    • Technical lifetime
    • Efficiency
    • Plant availability or maximum utilization time per year
    • Consumption or production of certain materials
    • Year of first commercial availability and last year of commercial availability of the technology.
