Non-technical losses are a component of energy losses associated with energy theft and fraud by the final consumers, hindering revenues of distribution utilities. This paper aims to compare the implemented solutions in the countries of South America to reduce non-technical losses. In this comparison, we introduce a new indicator based on the World Bank's database as input information. Considering that some regulatory agencies take policy actions related to non-technical losses to improve the quality of the electricity supply, we also present a correlation analysis of the proposed indicator and the electricity supply quality index. This analysis shows that in most of South America's countries, there is a high correlation within the studied horizon. An adequate characterization of the temporal variation in the proposed indicator can characterize the evolution of the consumers' perception of the quality in the electricity supply. This indicator allows each country's regulatory agency to analyze how the performed action is reducing non-technical losses concerning neighboring countries.

非技术性损失是与最终用户偷盗能源和欺诈相关的能源损失的一部分，这阻碍了配电公司的收入。本文旨在比较南美国家为减少非技术损失而实施的解决方案。在此比较中，我们引入了一个基于世界银行数据库的新指标作为输入信息。考虑到一些监管机构采取了与非技术性损失有关的政策措施，以改善供电质量，因此，我们还对拟议指标与供电质量指数进行了相关分析。分析表明，在大多数南美国家中，研究范围内存在高度相关性。所提出的指标中的时间变化的充分表征可以表征消费者对电力供应质量的看法的演变。该指标使每个国家的监管机构都能分析所采取的行动如何减少与邻国有关的非技术损失。
