This week, the ANEEL (National Electric Energy Agency) summoned Enel SP for failure to comply with the contingency plan agreed after the event of November 3, 2023, in addition to inadequate service after the storm on October 11, which left thousands of consumers without power for a week. According to the regulator, this is the first step in the possible process of expiring the concession.
Os extreme weather events have become increasingly common in Brazil, challenging the capacity of transmission and distribution networks to withstand these situations. Recent examples such as those that occurred in Rio Grande do Sul and São Paulo reinforce this new reality.
In view of this scenario, the ANEEL should open a Public Consultation in the next few days to discuss regulatory improvements with the aim of increasing the resilience of electricity grids to extreme weather events.
The topic was previously discussed during the Subsidy Call No. 02/2024, held between February 9 and April 9 of this year. In this first round, 1.045 contributions were received from 56 participants. Based on this initial analysis, the ANEEL identified the need to standardize contingency plans.
In the distribution sector, these plans should include climate monitoring, resource mobilization, training and simulations, reporting, coordination with external agencies, internal communication, emergency response teams, risk analysis and customer service, among other points.
For the broadcast sector, the ANEEL proposed minimum requirements, such as: risk identification and analysis, definition of contingency levels, action plan for each level, infrastructure, organization and availability of materials, training, regular simulations, updating of plans and continuous improvement. The minimum structure for transmission should include: backup equipment, emergency towers, cable storage, spare towers and tools.
Actions with less impact, but that are easy to implement in the short term, can be adopted in both distribution and transmission systems, such as urban tree management, communication plans with society and authorities, in addition to resource sharing.
“The role of energy distribution and transmission companies goes beyond simply delivering electricity; they are crucial to a number of economic and social activities. In times of climate change, with extreme events becoming increasingly frequent, the ability of these companies to respond promptly to supply disruptions is crucial,” the agency said. ANEEL in a press release.
