Each Brazilian consumer was, on average, without access to electricity for about 9 hours and 18 minutes throughout 2025, according to data released this Wednesday (15) by ANEEL.
Despite remaining at a high level, the indicator showed a 9,2% reduction compared to the 10 hours and 14 minutes recorded in 2024. The frequency of interruptions also decreased, going from 4,89 to 4,66 occurrences per consumer (a drop of 4,7%).
According to ANEELBoth indicators have shown a trend of improvement in recent years, reflecting compliance with increasingly stringent regulatory limits and the improved performance of distributors.
With regard to financial compensation, consumers received a lower amount in 2025 than in previous years.
According to the Regulatory Agency, the reduction is directly associated with the improvement in the quality of service provided by electricity distributors over the period.
The data presented shows that payments fell from R$ 1,122 billion in 2024 to R$ 1,002 billion in 2025, accompanied by a reduction in the number of compensated claims.
The decrease in the amounts paid is associated with the improvement in supply quality indicators, says the Agency, which point to shorter durations and lower frequency of interruptions in the electrical system.
Performance improvement
Compensation is paid automatically by distributors when regulatory limits for outages are exceeded. Thus, the drop in values indicates that the concessionaires have moved closer to, or within, the standards required by the regulation.
In 2025, the number of compensations fell from 27,3 million to 21,6 million, reinforcing the trend of improvement in service delivery, according to the ANEEL.
The observed evolution is related to a set of regulatory measures adopted in recent years, such as the revision of concession contracts, tariff incentives linked to quality, more intense oversight, and the definition of more stringent targets for distributors.
Distributor ranking
In the continuity ranking, which considers the DGC (Overall Continuity Performance), some distributors stood out positively. Among the large companies, the best results were recorded by CPFL Santa Cruz (SP), followed by Neoenergia Cosern (RN) and Equatorial Pará.
Among the smaller distributors, first place was shared by Muxenergia (RS) and Roraima Energia (RR), with Energisa Acre following. The survey also shows relevant movements in the ranking.
CPFL Piratininga was the company that advanced the most, rising seven positions, while Enel SP registered the biggest drop, falling nine positions compared to the previous year. As a result, the São Paulo-based distributor appears in 30th position among large concessionaires – a performance that keeps the company under regulatory scrutiny and may influence discussions about the continuity of its concession.
In a statement, Enel SP said that the ranking of ANEEL It takes into account different regulatory limits for each concession. "In São Paulo, for example, these limits are more stringent, which means that the ranking does not reflect the reality of the quality indicators," he stressed.
The company also reaffirmed its commitment to the service provided to its customers. "Enel emphasizes that the absolute quality indicators of its three distributors (Enel Rio, Enel Ceará and Enel São Paulo) are better than the national average. It is also worth highlighting that Enel São Paulo is the tenth company with the shortest duration of power outages (DEC) in Brazil," the company stated.
A piece of data considered relevant by ANEEL This is because, for the first time, all large distributors presented a DGC index lower than 1, indicating closer compliance with regulatory limits.
Challenges persist
Despite improvements in quality indicators, the electricity sector still faces significant challenges. The pursuit of more reliable services requires continuous investment in networks, technology, and maintenance, given the worsening effects of climate change, which puts pressure on distributors' costs.
At the same time, there is growing concern about the impact of these costs on energy tariffs, which are already at high levels and tend to rise with the expansion of the system, sector charges and new investments.
The issue gains even more relevance in a context of heightened political sensitivity surrounding the topic of tariffs, since the cost of electricity has a direct impact on residential consumers, economic activity, and inflation.
