Total Reliability

Started in 2020, the Total Reliability Project focuses on the use of new technologies to operate the distribution system, covering: the improvement of communication with field teams, the automation of all special equipment, the implementation of substations (SEs) or key stations (ECs) in all municipalities, the elimination of radialities by implementing automatic transfer in all substations and the implementation of autonomous reconfiguration (self-healing) in feeders where possible.

In this way the project establishes a new level of operational safety and efficiency for the operation of the distribution system, diversifying and deepening the digitalisation of business processes. In addition to the more than 15,000 new automated points to be implemented, there will be a remodelling of the processes previously mentioned.

21 new VHF (Very High Frequency) repeater stations were activated, reducing the shadow areas of communication with the existing teams, an aspect that gives more security to the workforce and the community and speeds up service in these areas. With the same objective, although in a complementary way, the bidding process was concluded and the contract signed for the use of satellite communication terminals, providing communication in the remaining areas of VHF shadowing, completely eliminating the regions without communication between the field teams and the operation centre.

Another 13 municipalities now have their own substations and switching stations, reinforcing the distribution system in the capillarity of the locations served, an aspect that adds resilience to the supply of energy and therefore promotes the development of economic activities of greater aggregation of value. As a vector of these same objectives, other 16 municipalities had their SE or CE removed from the radiality, now having a second source of power. A new 1238 pieces of equipment were automated, adding efficiency and flexibility in the operation and recomposition of the distribution network of the entire service region.

44 circuits with more than 5,000 consumers connected were reconfigured, reducing the impacts of manoeuvres, works and other events on the network. Besides the implementation of autonomous reconfiguration in 137 circuits with more than 3,000 consumers, taking to these locations a faster energy re-establishment and stretches of defect isolation considerably smaller.
