Abstract
In this article a model and a solution methodology is presented to solve the transmission network expansion problem, considering the selection of the wire size and the construction technology of the conductors for transmission lines for each new right-of-way. The optimization problem is solved using a specialized genetic algorithm that uses the logic of the Chu-Beasley Genetic Algorithm combined with an exact technique. The methodology is tested in the Colombian electric system of 93 buses and 155 candidate lines, which is modified in order to allow investment options for the selection of the conductors. The results obtained improve the traditional solution for the Colombian electrical system in the transmission planning study.

When the conductor type of the transmission lines is considered as a decision variable of the transmission expansion problem, and in particular when is considered HTLS conductors, it is observed a profit in the investment cost. The profit is relative to optimal solution that is found in the traditional transmission planning problem.
When it is considering options for conductor type, the space of solutions is significantly increased. Finally a solution of lower cost but with a greater computational effort is obtained.
To determine whether or not it is interesting replacing conventional conductors by HTLS conductors, it is necessary to use optimization methods to perform a thorough exploration in the space of solutions. This because in the optimization process, the solutions are topologically different and they have higher quality than the solutions obtained with traditional planning that do not consider the use of HTLS conductors.
