The Federal Electricity Commission (Comisión Federal de Electricidad - CFE) increased the rates paid by private electricity providers (generators) for using the public transmission network (the tarifa de porteo). These new rates were published after the Energy Regulatory Commission (Comisión Reguladora de Energía -CRE) approved a petition by the national electricity company to increase the costs to private electricity generators. The high and medium-transmission rates changed from 0.049 pesos to 0.2785 and 0.2586 pesos per KW/hr, an increase of 469 and 428%, respectively. The low-tension transmission rate was increased from 0.09799 pesos to 0.8928 pesos per KW/hr, an increase of 811%. The new transmission tariff, know as the porteo estampilla y porteo térmico will be applied to thermal plants as well as plantas de autoabastecimiento and renewables considered legacy plants, meaning their licenses were given by the regulating commission before the Law for Electricity Industry (Ley de la Industria Eléctrica - LIE). These new transmission tariffs follow assertions by the national government and others that the national electricity company is losing money from the low fees paid by private energy providers.
