The TAM of total losses for 2020 amounted to 19.61%, which represents a decrease compared to the 19.90% of the previous year.  
 
The absolute value of losses in GWh was lower than that of 2019. The greatest losses occurred in the first quarter as a result of the political context associated with the socioeconomic framework. 

In Regions II and III, new shantytowns continue to appear, along with the growth of the existing ones. The theft of energy in these areas continues to be the main factor behind losses.  
 
In 2020, the plan launched in previous years continued to be implemented, substantially increasing the installation of MIDE self-managed meters, under a plan that consists in having 250,000 meters in place in 2020. The plan is aimed at normalizing clandestine consumers, inactive customers and chronic delinquent customers. In 2020, 25,466 MIDEs were installed, 24,540 of which are currently enabled. 
 
The installation of the new type of MULCON network continued, leveraging the MIDE meter’s functionalities and increasing invulnerability in neighborhoods with a high fraud rate. Furthermore, we continued working on the development of analytical tools and artificial intelligence aimed at improving effectiveness as to where inspections to reduce energy theft are directed. 
 
In 2020, 518,000 Tariff 1 (small demand) meter inspections were carried out with a 54% effectiveness. As for energy recovery, in addition to the normalization of customers with MIDE meters, clandestine consumers were normalized by installing conventional meters. In all the cases, a striking rate of repeat fraud practices was noticed.
