ISA ENERGIA BRASIL is constantly evaluating opportunities in the market for its growth and has made progress in this area. The Company's strategy consists of expanding its presence in the national territory through auctions and/or acquisitions that generate synergies with existing operations, while respecting the minimum required return.

Since 2016, the Company has secured nineteen lots in transmission auctions held by ANEEL, totaling ANEEL investments (weighted by ISA ENERGIA BRASIL's participation) of R$ 15.8 billion, with an increase in RAP (2025/2026 cycle) of approximately R$ 2.1 billion following the commissioning of these assets.

Another important avenue for growth is investment in reinforcement and improvement projects. In the last 3 years, the Company invested an average of R$ 1 billion/year. The amount invested reinforces the commitment to generating sustainable value with projects that contribute to the expansion, security of the electrical energy transmission system, and energy transition in Brazil, thus consolidating the increase in capacity and modernization of its assets that began in 2020. Demands for investment in reinforcements and improvements are more concentrated in renewed contracts, as well as contract 059, in the state of São Paulo, from ISA ENERGIA BRASIL. Today the Company has R$5.0 billion in investments in projects already authorized by ANEEL and which will be carried out between 2025 and 2029. The renewal of assets is a fundamental tool for adequate management of the transmission system and guaranteeing excellent service provision, allowing reduction of operation and maintenance (O&M) costs, longevity of assets and has investment costs (CapEx) remunerated in accordance with Regulation.
