Abstract

This paper analyzes data provided by ENEL-CODENSA with information about substation assets, including sulphur hexafluoride (SF_6) containing equipment and its top-up operations over the last ten years. The information has been used to estimate the total SF_6 mass in the current fleet and to determine historical emissions. The environmental and economic impacts are evaluated using the obtained results on simple models. Recommendations are made in order to mitigate the estimated impacts.
