MARKAL and TIMES generate technical-economic models of global, regional, national and local energy systems. TIMES is the recent evolution of MARKAL. Users define the Reference Energy System, from primary energy resources to demand for energy services. TIMES models represent the partial equilibrium evolution of the system over a user defined time horizon, with variable time intervals. Based upon the characterisation of hundreds of energy technologies and demand devices, MARKAL and TIMES models calculate the optimal mix of technologies and commodities. These models enable you to evaluate energy plans, environmental policies, climate mitigation scenarios and new technologies in trade-off modes. Scenario dependent energy balances and inventories of GHG emissions can be projected. Several variants are available, including stochastic for calculating hedging strategies, general equilibrium versions, lumpy investments, energy security risk. Global TIMES models, such as the TIMES Integrated Assessment Model (TIAM), include a full representation of the climate equations and build scenario constraints to a predefined global atmosphere temperature increase.
