Quality in power supply to its 15.5 million customers is a priority for Neoenergia. Investments in networks and innovation so that services are better and better are proven by the performance of the company's distributors. In the first quarter of 2021, the group's concessionaires – Coelba (BA), Celpe (PE), Cosern (RN), Elektro (SP and MS) and Neoenergia Distribuição Brasília – maintained the DEC (Equivalent Interruption Duration per Consumer Unit) indicators better than the targets established by the National Electric Energy Agency (ANEEL). This means that consumers have a more continuous and reliable supply, with fewer hours of power outages.    

"The result demonstrates the company's commitment to its customers and to the development of the country. Our good performance is a reflection of the investments made in technology, expansion and improvements, which grew 49% in the first quarter of 2021alone", says the Director of Distribution of Neoenergia, Fulvio Machado.  

Coelba recorded the best historical result, withDEC of 11.77, while the limit established by ANEEL was 13.68. The Bahian concessionaire also broke another record in March, reaching a monthly index of 0.83 hours, the lowest ever recorded in the historical series of the month. The performance is 41.5% better than that achieved in the same period last year.  

The indicator in Celpe was 12.36, below the maximum value established by the agency of 13.27. Cosern presented DEC of 8.49, better than the regulatory body's target of 11.35. In Elektro, the indicator was 7.63, while the limit was 8.15. In 28 days of group management at Neoenergia Distribuição Brasília, the company has already recorded the best index in the historical series of the month – in March 2021, the DEC was 0.5 hours, a reduction of 12% compared to the period last year.  


To maintain the quality of services better and better, investments in distribution reached R$ 873 million between January and March of this year, destined to actions such as network expansion, asset renewal, network improvements and loss fighting. The contributions are also part of Neoenergia's innovation strategy to prepare for changes in the electricity sector, where companies increasingly have the role of Distribution System Operator (DSO). For this, distributors need to have more and more control and measurement technologies.  

An example is the installation of automation equipment, such as self healing, which allows recomposition in case of failures, usually caused by external factors such as atmospheric discharges and tree falls. Currently, the company's distributors already have more than 13,000 points. These equipments have intelligence capable of isolating the stretch hit by any problems and repairing defects automatically, restoring power quickly to the largest number of customers.

Modernization also goes through areas of companies such as remote management of network equipment and substations. The control of the activities of the field teams is also carried out in an automated way through software, which allows prevention activities and failure solution with more agility.  

Contributing to innovation in the electricity sector, Neoenergia also invests in R&D projects. This is the case with the creation of a qualmeter, equipment aimed at measuring the quality of energy delivered to customers, which makes measurements of continuous oscillography, using data compaction technique with an accuracy considered superior to international references.
