An analysis of the principal methods of transmission loss allocation acting for generators and loads is presented. Two methods based on the pro-rata technique, three marginal procedures, one method based on proportional sharing and one more method based on the theory of electric circuits are discussed. The algorithms are tested, firstly, with didactic systems for easy verification of potentialities and disadvantages, following of a result evaluations with a large systems (IEEE 118). The presented and discussed results consider: the location and the magnitude of generators and loads; the possibility of having agents well or badly located in each configuration of the net; the performance when variations in the network happen; and the discriminatory behavior. Conclusions and recommendations are stated.
