Industrial and commercial electrical designs

Electrical project engineering

Industrial and commercial electrical designs

We develop the electrical designs that give rise to your industrial or commercial project: calculation reports, single-line diagrams, and technical specifications under RETIE 2024. Because we are also manufacturers of switchboards and cells and execute projects, we design with real construction in mind—buildable and installable, not just a set of drawings to hand over.

What an electrical design solves when it is done by the people who manufacture and build

Design deliverables

What an industrial or commercial electrical design includes

We develop your project’s electrical engineering from start to finish: load survey, calculation reports, single-line diagrams, specification of substations, switchboards and networks, and drawings coordinated with the construction work. The design is delivered ready for tendering, construction, or manufacturing, with the advantage that we are the ones who can later execute it.

  • We design like those who are going to build: engineering is conceived to be manufactured and installed, not just delivered on paper.

Substation and medium-voltage design

We design electrical substations and medium-voltage networks for industrial plants and commercial projects: transformer sizing, cells, protections, and coordination with the grid. The engineering is developed under RETIE 2024 and is ready to manufacture and install the equipment that makes up the substation.

  • Sizing of transformation, cells, and protections
  • Protection coordination and associated electrical studies
  • Reports and drawings under RETIE 2024

Switchboard and low-voltage system design

We design the switchboards and low-voltage systems for your installation: distribution, transfer, motor control, power, and power factor correction. Because we manufacture switchboards under IEC 61439 and RETIE 2024, the design is specified using the real criteria with which the equipment is later manufactured.

  • Design of distribution, power, and control switchboards
  • Specification of currents, voltages, and forms of segregation
  • Design aligned with manufacturing under IEC 61439 and RETIE 2024
  • Each design is developed under RETIE 2024, with calculation reports and single-line diagrams that support the project..
  • Product and engineering under one roof: the design is consistent with the switchboards and cells we manufacture.

Calculation reports and single-line diagrams

We prepare the calculation reports, single-line diagrams, and technical specifications that support your electrical project. These are the documents that back the project before the project supervisor and the certification body, and the basis on which it is manufactured and installed.

  • Calculation reports for loads, conductors, and protections
  • Single-line diagrams and load schedules
  • Technical specifications for equipment and materials

Design coordinated with manufacturing and installation

We coordinate the electrical design with the rest of the project and with subsequent execution: engineering is aligned with the civil works, the schedule, and the manufacturing of the equipment. This way, the design reaches the site without contradictions and construction progresses without rework.

  • Coordination with civil works and the project schedule
  • Design aligned with the manufacturing of switchboards and cells
  • Technical support during construction
  • The same design can be tendered, built, or manufactured: you decide how far you involve us in execution.

Electrical designs developed by a firm that also manufactures and builds


Energizar’s scope is flexible: we deliver the electrical design for your industrial or commercial project—calculation reports, single-line diagrams, and specifications under RETIE 2024—and, if you decide, we also manufacture the switchboards and cells and execute the work. By designing with real manufacturing and installation criteria, our engineering avoids the typical rework of drawings that were never intended to be built.

How we develop each electrical design

Ingeniería pensada para construirse

We design using real manufacturing and installation criteria, because we are the ones who can later execute the work. Engineering is conceived to be built, which reduces rework and cost overruns on site.

Cumplimiento RETIE 2024 desde el diseño

Each design is developed under RETIE 2024 and the applicable technical standards, with calculation reports and single-line diagrams that support the project and facilitate subsequent certification.

41 años de experiencia y respaldo local

Energizar has 41 years in the Colombian electrical sector, with in-house manufacturing and multi-brand integration. The design is backed by a team present in the Western Region and local after-sales support.
