ISA Energia

What ISA Energia does

ISA Energia is a privately held Peruvian electricity transmission utility that builds, operates, and maintains high-voltage transmission infrastructure across the country. Founded in 2002 and headquartered in San Isidro, Lima, the company operates through four subsidiaries — Red de Energía del Perú (ISA REP), Consorcio Transmantaro (ISA CTM), Interconexión Eléctrica ISA Perú, and Consorcio Eléctrico Yapay (CEYA) — which are wholly or majority owned by Colombia's Interconexión Eléctrica S.A. E.S.P. (ISA group). ISA Energia's core asset base includes more than 12,000 kilometers of transmission lines operating at 60 kV, 220 kV, and 500 kV, 86 substations, and two control centers delivering real-time grid management across 21 Peruvian departments. It was the first Latin American electricity transmission company to obtain ISO 55001 certification for asset management and the first energy-sector issuer in the region to launch an international green bond (USD 400 million, April 2019).

The company earns revenue through regulated transmission tariffs under long-term concessions awarded by Peru's Ministry of Energy and Mines (MINEM), supplemented by construction revenue from new infrastructure projects and maintenance services. Its primary customers are Peruvian electricity distribution companies and large industrial free clients, with the government acting as concession grantor and regulator rather than a direct off-taker. Business-to-government (B2G) and business-to-business (B2B) sales motions dominate, with competitive bidding for new transmission concessions. In 2022, ISA Peru acquired Orazul's Peruvian operations, expanding the portfolio to 3 concessions, 3 expansions, and 8 additional substations.

Recent strategic activity includes a March 2025 BRL 1.17 billion asset-swap transaction with AXIA Energia (former Eletrobras entity), a November 2025 investment in Future Energy Ventures Fund II (EUR 235 million European EnergyTech VC fund), a USD 615.86 million financing event in November 2025, and ongoing construction of the Ampliación 23 substation expansion project (2026). The company is also expanding into renewables interconnection, having constructed a transmission line for Enel Colombia's 180 MW Atlantico solar park in 2026, and obtained Environmental Impact Study approval for a new transmission project in the San Martín region in May 2026.

Expansion highlights6 records

Broad incumbents

• Iberdrola: Global renewables-heavy utility with a regulated transmission and distribution arm operating across multiple jurisdictions. Relevant benchmark for grid investment discipline and renewable integration, though far broader than ISA Energia's transmission-only focus.
• National Grid: UK-listed regulated electricity and gas transmission operator. Comparable on regulated TSO economics and large-scale infrastructure ownership, though materially larger and more geographically diversified.
• Engie: Global energy operator with significant transmission infrastructure in Latin America (including Brazil). Overlaps with ISA Energia on regulated asset ownership and renewable interconnection, but Engie's portfolio is much more diversified across generation and networks.
• Red Eléctrica Corporación (Redeia): Spain's national TSO and global benchmark for transmission-only utilities. Operates a regulated HV grid under a similar concession-style framework; comparable on operational model even if far larger and more diversified geographically.
• Terna: Italy's national TSO operating Europe's largest regulated transmission grid. Analogous regulated utility structure with system-operator functions (control centers, grid services) similar to ISA Energia's two-center operations.

Direct peers

• Celeo Redes: Spanish-origin transmission operator with significant regulated assets in Chile and Brazil. Runs long-haul HV lines and substations under concession frameworks highly comparable to ISA Energia's Peruvian operations.
• Interconexión Eléctrica S.A. (ISA): The Colombian state-owned parent and Latin America's largest energy transmission operator. Same TSO business model, same concession-based economics, same regulatory/operational playbook — ISA Energia is essentially ISA's Peruvian platform.
• Enel Transmisión Perú: Peru's other major regulated transmission operator (part of Enel Group), competing for the same MINEM concessions and serving overlapping distribution companies and free clients in the Peruvian grid.
• Transelec: Chile's largest high-voltage electricity transmission operator running a similar regulated, concession-based business across thousands of kilometers of lines and dozens of substations. Most directly comparable LatAm peer to ISA Energia's operating model.
• TAESA (Transmissora Aliança de Energia Elétrica): One of Brazil's largest private electric transmission concessionaires, operating thousands of km of HV lines under ANEEL-regulated tariffs. Closest Brazilian analogue in scale and business model.
