As largest package in 2022/01 auction, the strategic barrier on this 1,060-mile, 500 kV double-circuit corridor for Neoenergia team was clear: how to reduce land use and overall CAPEX enough to win the auction — without compromising long-term reliability. EMAGE was engaged before the tower family was frozen, before foundations were issued for construction, and before conductor stringing was scheduled, and walked the full qualification cycle alongside the owner over roughly two years — scheme optimization, custom CICA product development, full-scale type and system testing, on-site installation enablement, and final energization in January 2026, 21 months ahead of the ANEEL deadline. This complete, rigorously documented certification path — covering design, product, lab validation, field execution, and commissioning — is what gave the owner the confidence to deploy CICA at the scale of a national-asset corridor.

Proven Across Voltage Classes. Validated in Real Grid Operations.
From 2009 to 2019, CICA underwent a decade of pilot applications across over 100 projects, covering all voltage levels and various operating conditions. Its solid project track record has fully verified the technical reliability and mature solution performance. Since 2019, CICA has evolved from limited small-scale trials into full-scale comprehensive application across entire transmission lines and complete engineering projects.

500 kV Pumped-Storage Connection — Reliability through Protected Forest
The 500 kV double-circuit line is the dedicated grid connection for a pumped-storage hydropower plant — a renewable-enabling asset whose value to the system depends entirely on a transmission link that is reliable from day one. The route runs through dense, ecologically sensitive mountain forest at elevation, in a Class C pollution and high-humidity environment, where every additional meter of right-of-way means protected canopy lost. A conventional steel-arm double-circuit would have forced a difficult trade-off between corridor width and ecological permitting. EMAGE delivered a compact CICA double-circuit instead — corridor narrowed by 3.2 m (10.5 ft), tower height reduced by 4.8 m (15.75 ft), tower weight cut by 15%, all while holding full 500 kV electromechanical performance. The renewable plant is firmly connected, the forest envelope is preserved, and the line is engineered for 50+ years of service in one of most demanding ambient environments.

220kV Quad-Circuit CICA Tower — Megacity Capacity Without New Corridors
Shenzhen — one of the world's densest megacities — faces a structural transmission problem that no amount of capital alone can solve: load keeps growing, but right-of-way for new corridors effectively does not exist. Reinforcing the urban backbone with four parallel 220 kV circuits the conventional way would have required four separate routes through land that is, for practical purposes, fully spoken for — a project that would have stalled in permitting before a single tower was raised. EMAGE solves the problem with compact engineering deployment of a quad-circuit CICA — four full circuits stacked on a single, compact structure within a single right-of-way. The configuration narrows corridor width by 26%, cuts tower steel by 15–20%, and reduces deforestation by 10%, while delivering the dispatchable capacity equivalent to four conventionally-built single-circuit lines. For a city utility planning at the absolute ceiling of available land, this is the difference between a project that gets built and a project that does not.
