This work outlines a metodological proposal for the elaboration of quantitative indicators of the impact caused by electrical power transmission projects, using the perspective of the model of environmental administration by dimensions (Physical, Biotic, Cultural, Economic, and Political). The model achieved an integral and interdisciplinary analysis, managing to determine what the degree of impact that a project generates on a dimension and its relationships to the others, moreover the indicators identified are useful tools that should help support planning, project formulation, decisions making, and environmental studies, such as: environmental management plans and greater efficiency in the estimation of administrative costs, as well as in the techniques of generating location alternatives, and also may lead to better administration of economic and human resources, among others.
