Full-Cycle EPC Execution Substations and Grid Connections up to 400kV

We deliver complete engineering, procurement and construction (EPC) services for electrical systems up to 400 kV — from initial concept to energization.


Every project is executed under one management structure, combining design, equipment supply, construction, automation and commissioning into a single, accountable process.


This integrated approach guarantees predictable schedules, full technical traceability and lasting operational reliability across transmission and distribution infrastructures.

From Grid to Reactor

Engineering, Procurement & Construction: One Line of Responsibility

Our EPC model combines engineering precision, controlled procurement, disciplined construction and verified commissioning.
Every element  from primary equipment to automation  is delivered within a single, auditable process, minimizing risk and ensuring lasting reliability for grid-scale infrastructure.

Engineering & Design

We start by translating technical requirements into actionable solutions.

    • Grid analysis, protection coordination and system planning
    • Layouts and schematics for HV/MV substations and grid connections
    • Civil and structural design aligned with technical and environmental standards
    • Retrofit and modernization concepts for existing installations

Procurement & Logistics

We secure all materials and equipment through our global network of certified suppliers.

  • Technical validation and conformity with project specifications
  • Customs, logistics and just-in-time delivery planning
  • Supply of transformers, switchgear, automation and SCADA components for systems up to 400 kV

Construction & Installation

We coordinate multidisciplinary teams to execute civil, electrical and automation works under one supervision line.

  • Foundations, structures, cable routing and field assembly
  • Installation of primary and auxiliary systems
  • Mechanical and electrical testing of installed equipment
  • Compliance with ANRE and CNCAN regulations

Automation, SCADA & Integration

We connect the entire system through digital protection and control architectures.

  • Parametrization of protection relays and automation systems
  • SCADA and remote-control integration
  • Communication network configuration (IEC 61850 compliance)
  • System-level functional testing

Commissioning & Handover

We deliver fully verified, operational assets.

  • Energization procedures and on-site verification
  • Protection and SCADA testing under load conditions
  • Training and documentation for client operation teams
  • Long-term maintenance and performance support
