Regional energy security goes South: Examining energy integration in South America

Abstract

This article proposes to promote a regional approach to achieving energy security in South America. To this end, it first discusses the concept of energy security, concluding that it is a concept slippery, hard to define universally, because it is polysemic, multi-dimensional and context-dependent. Analyzing the South American case, initially focusing only on the Mercosur countries, we identify that there are different regional integration initiatives, such as the case of Itaipu Dam and GASBOL Pipeline, however the experiences are exclusively based on binational initiatives. Through an energy modeling called Open Source energy Modelling System using a new framework named South America Model Base (OSeMOSYS SAMBA), four scenarios are created with different levels of energy integration in the region. It is concluded that more integrated scenarios lead to a reduction in the need to increase installed capacity, as well as lower geographic and socio-environmental impacts, due to resource optimization and greenhouse gas (GHG) mitigation.
