In 2025, TAESA issued R$1.45 billion in Green Bonds to support its sustainability initiatives, complementing ongoing investments in social responsibility and environmental monitoring technologies. TAESA has accelerated capital expenditures, with R$1.3 billion spent in the first nine months of 2025, progressing projects like Saíra, Tangará, Ananaí, and Juruá to enhance its capacity and revenue streams. Moreover, TAESA continues to expand through strategic partnerships, acquisitions, and infrastructure upgrades, aiming to grow its regulatory annual permitted revenue (RAP) to BRL 4.4 billion by 2026.
TAESA operates through a number of subsidiaries, including Brasnorte Transmissora de Energia S/A, Ananai Transmissora de Energia Elétrica S/A, and Companhia Transudeste de Transmissão.
