Grande Sertão

What Grande Sertão does

Grande Sertão – Transmissora de Energia S.A. is a privately held Brazilian electric power transmission group organized as a holding with three core operating subsidiaries — Grande Sertão I, II and III Transmissora de Energia S.A. — each holding 500 kV transmission concessions awarded at the ANEEL Leilão de Transmissão 01/2024. The portfolio covers approximately 1,933 km of 500 kV lines (GS I: 373 km; GS II: 934 km; GS III: 626 km) with ~2,920 towers, crossing nearly 60 municipalities across six Brazilian states (Rio Grande do Norte, Paraíba, Pernambuco, Alagoas, Bahia, and Minas Gerais). Its core technology is high-voltage transmission infrastructure integrated into the National Interconnected System (SIN), with associated substations developed under comprehensive environmental licensing (EIA/RIMA, LP, LI, LO, ASV, AMF, IPHAN clearances).

The group's commercial model is institutional and concession-driven: it acquires rights by winning ANEEL public auctions, signs a concession contract with the federal government (Ministério de Minas e Energia), and delivers transmission services to the SIN under regulated tariffs — the Receita Anual Permitida (RAP) — coordinated by ONS. Revenue is therefore entirely regulated and contract-based, with no retail or per-unit consumer pricing. Capital formation is executed through Brazilian capital markets, with four separate debenture issuances (GS I, II and III 1ª Emissão in April-May 2025 and GS III 2ª Emissão in April 2026) supplemented by a Banco do Nordeste do Brasil (BNB) credit facility for GS III. The company is currently in the construction and licensing phase across most of its portfolio, with operations support spanning six states, headquarters in Botafogo (Rio de Janeiro), and an 11-50 employee base.

The company is a signatory of the UN Global Compact, holds five consecutive Great Place to Work (GPTW) certifications, has obtained IBGC Audit Committee training for its C-suite, and operates a Contato Seguro 24/7 whistleblower channel. Sister companies within the broader corporate group include Tropicália Transmissora, PCH Braço and Guaporé Sul Transmissora. Strategic positioning centers on reinforcing the SIN and evacuating renewable energy generated in Brazil's Northeast, with ESG programs (Na Mão Certa, +Que Respeito, Desplastifique) supporting institutional differentiation in the regulated transmission sector.

Direct peers

• ISA CTEEP: Major Brazilian transmission concessionaire (subsidiary of ISA Group from Colombia), operating over 24,000 km of high-voltage transmission lines. Directly comparable as an ANEEL-regulated transmission concessionaire with RAP revenue model and multi-state footprint.
• Alupar Investimentos: Brazilian holding company focused on power transmission and generation concessions across Brazil and Latin America. Comparable as a transmission concession operator with multiple ANEEL auction wins and regulated RAP revenue.
• Equatorial Transmissão: Transmission arm of Equatorial Energia group, operating high-voltage transmission concessions across multiple Brazilian states under ANEEL regulation. Directly comparable in regulated transmission business model and concession structure.
• Taesa (Transmissora Aliança de Energia Elétrica): Brazil's largest publicly listed electric power transmission company, operating thousands of km of high-voltage lines under ANEEL concession contracts. Directly comparable business model of concession-based regulated transmission revenue (RAP) across multiple regional assets.

Broad incumbents

• Chesf (Companhia Hidro Elétrica do São Francisco): Eletrobras subsidiary focused on the Northeast region of Brazil with extensive transmission and generation infrastructure in the same geographic zone as Grande Sertão. Comparable regional focus in Northeast Brazil and 500 kV transmission operations.
• State Grid Brazil (CTG Brasil): Brazilian subsidiary of China's State Grid Corporation, one of the world's largest utilities, with significant transmission operations in Brazil acquired from Eletrobras and other auctions. Comparable in regulated high-voltage transmission but with global scale.
• Furnas Centrais Elétricas: Brazilian federal generation and transmission utility, subsidiary of Eletrobras, with extensive 500 kV transmission network. Comparable in 500 kV transmission technology and integration into SIN, though operates as part of larger state-owned group.
• CPFL Transmissão (CPFL Energia / State Grid): Brazilian transmission and distribution group controlled by State Grid, operating regulated transmission concessions. Comparable as an ANEEL-regulated transmission operator, though as part of broader generation/distribution portfolio.
• ENGIE Brasil Transmisão: Brazilian subsidiary of global energy major ENGIE, operating generation, transmission and distribution assets. Comparable as a transmission concession holder, though as part of a broader diversified energy portfolio rather than a pure-play transmission company.

Others

• MME / ONS regulatory ecosystem (EPE, ANEEL counterparties): EPE (Empresa de Pesquisa Energética) and ONS (Operador Nacional do Sistema Elétrico) are key institutional counterparts and partners in Brazilian power transmission planning, although they are regulators/operators rather than peers in the strict sense.
