The GGT System is an innovation because it is the only monitoring tool that:

1. Uses Artificial Intelligence algorithms for the processing of satellite images to identify all spans of transmission lines affected by burn scars;
2. Uses algorithms that automatically detect variations in the amounts of vegetation within each span of the monitored transmission lines, validating, or not, vegetation suppression activities carried out in the field by the transmission companies without the need for displacement by ANEEL’s inspection teams;
3. Automatically generates monitoring reports containing diagnostics on the adjustments of maintenance performed by the transmission companies in the safety lanes of transmission lines, allowing ANEEL’s inspection teams to act preventively and with enough assertiveness in order to mitigate the risks of blackouts caused by wildfires throughout Brazil.

Currently the following actions are happening:

1. The information produced by the GGT System is being used to subsidize the issuance of preventive alerts for the transmission companies and to subsidize meetings and inspection processes instructed by ANEEL;
2. Training is being carried out on the Artificial Intelligence algorithm in order to further improve assertiveness in detecting the scars of the wildfires that intercepted the monitored transmission lines;
3. Evaluations of the sensitivity of the vegetation suppression detection algorithm are being carried out to verify whether it is possible to increase the validation rates of maintenance performed in the spans of the monitored transmission lines;
4. The geographical files of new transmission lines that will be included in the permanent monitoring of the GGT System are being validated.

1. ANEEL: Federal Regulatory Agency that idealized the project. It has mapped needs, defined objectives and is who actively monitors the results. It uses the information generated to subsidize the processes of responsive inspection that seek to ensure quality in the provision of public electricity transmission services in Brazil.
2. Imagem Geosistemas: It is the private company contracted by ANEEL to develop the geotechnology solutions necessary for the GGT System.

1. ANEEL: Is the main stakeholder. It uses the information generated by GGT to subsidize responsive enforcement actions.
2. Transmission Companies: Use the information generated by GGT and the alerts issued by ANEEL to improve their transmission line maintenance processes and reduce the risks of blackouts caused by wildfires.
3. Brazilian electricity consumers: They are the main beneficiaries of the increased reliability in the electricity supply verified since GGT was launched.

From 2017, when the GGT System was launched, until 2022, there was a 89% decrease in shutdowns caused by wildfires on the monitored transmission lines, although increases in the annual amounts of wildfires have been recorded throughout the country. These data were obtained from routine calculations performed by the Brazilian Electric System Operator (ONS) and the Brazilian Institute for Space Research (INPE). The goal is that the GGT continues to be an inducer of improvements in maintenance management processes adopted by transmission companies, keeping low the amounts of shutdowns of transmission lines due to wildfires, even with the increase in the number of lines in operation in Brazil.

The main challenges faced were:

1. Make transmission companies aware of the need to increase investments in transmission line maintenances in order to improve the quality of inspections and vegetation suppressions carried out, resulting in greater reliability for the System;
2. Obtaining geospatial archives of transmission lines on which the geographical coordinates of the towers and spans represent the exact locations in the field, allowing the appropriate processing of satellite images in the areas of interest;
3. Make the transmission companies send monthly to the GGT informations and photographic evidences that demonstrate the real situations of the maintenances performed in the field for all spans of the monitored transmission lines.

The following conditions are required:

1. Partnership between the public entity, holder of police power, and private entities, holding the technical expertise necessary for the development of a tool using cutting-edge technologies capable of expanding the scope of monitoring and enforcement actions;
2. The involvement of transmission companies responsible for the proper maintenance of transmission lines and public authorities responsible for supervision;
3. Creating rules and implementing responsive regulatory procedures that encourage transmission companies to improve their transmission line maintenance management processes.

The innovation undertaken in Brazil by ANEEL with the GGT System can be replicated by regulatory agencies from other countries that also face the same problems of transmission lines shutdowns caused by wildfires. Transmission companies can also replicate the innovative solution developed by ANEEL in order to evaluate, through satellite image processing, the exact extensions of vegetation suppressions performed by field teams, who are often hired specifically for these tasks.

Outages of transmission lines due to wildfires were considered as poorly manageable for a long time in Brazil. However, from the moment ANEEL decided to create innovative solutions capable of monitoring in near real time the quality of maintenances carried out by the transmission companies responsible for the concessions of the Brazilian transmission lines, there was a significant improvement in the performance of these lines, resulting in greater reliability in the supply of electricity to the Brazilian population. This demonstrates that it is possible to obtain improvements in the quality of public services delivered when there are effective initiatives by public entities responsible for the national public policies.

The GGT System presents itself as a very effective Responsive Regulation tool, making use of innovative geoprocessing technologies that seek the rational use of public resources to increase the safety and the reliability of the operation of the Brazilian Electric System.
