SUMMARY:

Electricity transmission and distribution processes generate energy losses that impact the efficient functioning of electrical systems. Total energy losses are subdivided into technical and non-technical losses. Technical losses occur naturally due to physical properties that cause the dissipation of part of the energy generated in the transmission lines and other components of the system, being generally stable. Non-technical losses, also called commercial losses, generally occur due to electricity theft, fraud, meter reading errors and defective meters, being related to socioeconomic factors, system corruption and to managerial aspects of utilities. The average real and regulatory non-technical losses, weighted on the billed low voltage market, were 15,3% and 12,4%, respectively, in the period from 2008 to 2015. This considerable amount of losses causes a reduction of revenue for the utilities and makes the tariffs less and less reasonable. This happens because the losses are transferred to the consumers up to the limit of regulated non-technical losses, at the time of the utilities tariff review. This transfer has direct and indirect impacts for utilities, the government, and consumers, generating a vicious cycle of non-technical losses. In this perspective, this dissertation has three synergistic objectives, namely: i) through a traditional literature review, survey the most relevant national and international publications to the non-technical losses research agenda; ii) to undertake a pioneering bibliometric analysis, to systematize the measures to mitigate the commercial losses hitherto proposed by the literature, to identify the major references of articles and authors on the subject, present the research areas that address the topic, the most relevant journals, the countries that publish the most, and the most used keywords, besides identifying the evolution
of the research topic; lastly, iii) to measure the direct and indirect impacts on the household electricity consumption and on Brazil’s Gross Domestic Product (GDP) of partial transfer of non-technical electricity losses in the low voltage market on tariff. To reach this last goal, it was used the input-output methodology and the Brazilian matrix for the year 2015 provided by the IBGE with the vector of family consumption disaggregated by income deciles. The results showed that when the amount referring to the cost of commercial losses was not transferred to families and redistributed on consumption basket, it had a direct and indirect impact of BRL 12.9 billion, which represented a net impact on Brazil’s GDP of BRL 5.1 billion. This measure would be more equitable and fairer, in addition to leading to more reasonable tariffs.
