This paper brings the development of a computational tool to help the energy planning in rural electrification areas by using the main software available on the world market or cited in scientific literature, as in the reference. After identifying its main limitations, a product in Portuguese was obtained, which compares the extension of conventional electric grid to the main small size renewable energy sources under use in Brazil. It also brings the innovation in the dimensioning and in the use of electric energy generation by the local biogas production. For the program validation, the results obtained by the tool were compared in two real study cases of rural electrification.
