Energy utilities are including in their projects future climate studies. The main objective is protect assets and maintain operations in a scenario in which transmission lines are being increasingly impacted by weather events , the electrical discharges and more recurrent fires.
During the II EMSEA (National Climate Change Meeting for the Energy and Agribusiness Sector), carried out by Weather, the participating companies highlighted that they are carrying out analysis of future weather models to make adaptations and climate impact mitigation measures about the transmission lines.
“It is not enough today to just look at the history of events, because the scenario has changed with global warming, so analyzes of future meteorological models are necessary so that adaptations and measures to mitigate impacts on the lines can be made”, he stated. Sergio Antezana, transmission superintendent at Alupar.
“In this way, we are able, for example, to prune vegetation more intelligently in areas at risk of fire or identify where there may be heavy rain and send teams to act quickly in the event of a shutdown,” he added.
In Climatempo's assessment, to contribute to the issues of energy transition and decarbonization, the transmission segment currently needs more infrastructure to take renewable energy primarily generated in the North and Northeast of Brazil to the large consumption centers in the South, Southeast and Midwest.
“Brazilian electrical generation today is 90% renewable, but more transmission lines are needed to help promote the national energy transition, cleaning up consumption in large centers,” noted Dominic Schmal, ESG director at EDP.
Transmission lines scenario
In 2023, more than 10 thousand kilometers of transmission lines auctioned. Ana Carolina David, Communications, Sustainability and Institutional Relations Manager at ISA CTEEP, considered that the challenge will be to implement new projects with low-carbon technology and infrastructure adapted to climate change.
“We have carried out studies to adopt adaptive measures in projects, but the most extreme weather events are a reality and the challenge is to bring this discussion of impacts to the regulation of the sector as well”, pointed out Ana.
In this context, the ANEEL (National Electric Energy Agency) carried out subsidies in the first half of the year to assess the need for regulatory intervention associated with increasing resilience to climate events in transmission and distribution systems.
Second Djane Fontan Melo, coordinator of Secretariat of Innovation and Energy Transition of the ANEEL, the Agency is attentive to the flow of clean energy to areas of greatest consumption and the challenges of resilience of lines in the face of extreme weather events, as ways to collaborate with the energy transition and guarantee Brazilian energy security.
