Energy studies we carry out short, medium and long-term energy analysis studies for generation projects. Energy studies We carry out short, medium and long term energy analysis studies for generation projects. The energy analysis studies of generation projects seek to determine the impact of the entry of operation of a generator on the system’s marginal cost and the benefits that the country receives from the generator’s operation. These studies are carried out with the SDDP “Stochastic Dual Dynamic Programming”, a hydrothermal systems simulation model. We carry out studies of spot and contract price projections with the SDDP model taking into account technical characteristics of all the plants in the system, fuel prices, operation and maintenance costs, reservoir level, in-service date of future projects, among others.
