CEL is one of the biggest hydro power producers in Central America and optimizes the schedules of its generation plants on the liberalized Central American market based on the results of multi-level stochastic optimization models.

For CEL, a predecessor version of the software DT.HYDROTHERMAL was developed based on the scientific research on stochastic optimization carried out by the founder of Decision Trees at a renowned Swiss business university. With the help of this software, CEL has been able to significantly increase the profits from hydro power generation over the course of the past few years.
