Resumo: The increasing integration of electricity generated from renewable sources in the national electricity generating systems are posing new challenges to these systems management. In particular, in off-peak hours, the system management must ensure a suitable destination to any exceeding electricity created. One solution to deal with this problem is to export. Portugal has belonged to the leading group of countries where renewable sources grew most. Therefore its being studied for this country, the relationship between wind power electricity and the electricity exports for the period July 2007 to 2012, on a daily basis. Given the strong endogeneity between wind sources, exports, and the electricity generated in the ordinary regime, the methodology Vector Autoregressive (VAR) is used. This option also allows to evaluate the nature of the relationships without the prior need to distinguish endogenous from exogenous variables. The results show that causalities exist between the variables, that is, they interact with each other. In addition, there is a bidirectional causal relationship between consumption and production of wind energy and between the proxy electricity export and consumption. This study shows that there is endogeneity between variables and a positive correlation between exports electricity and wind energy production in Portugal. These results will help policy makers to take balanced positions within the power system.
