The methodology implies in the systematization of the impacts and the mitigation actions taken, studying the impacts considering the sustainable development and energy planning. The chosen Case Study is a 500 kV-transmission line in the Brazilian Amazon rainforest, crossing a primitive forest and rushing rivers. The results are that the greatest risk is in the political dimension, due to cultural reasons, so this dimension shall be a priority to be considered in future similar projects.
