Design of electricity supply facilities with voltage up to 220 kV

NIIEFA-ENERGO, LLC performs work involved in designing traction and step-down substations with primary voltage of up to 220 kV. The enterprise is a member of non-commercial partnership of the Baltic Association of Designers self-regulatory organization; it has a competency certificate for certain types of works that affect the safety of capital construction projects.


Types of works performed:

  • main circuit design;
  • architectural and building aspects;
  • electric machinery and electric mains location plan;
  • installation of electric machinery;
  • power grounding and lightning protection;
  • relay protection and automation (including coincidence circuits and feature determination tables for shutdown terminals);
  • Automated Process Control Systems;
  • heating and ventilation;
  • lighting;
  • fire alarm systems;
  • ther electrical engineering work (ventilation and fire-fighting automatic systems, etc.);
  • optional equipment assignments for plants.

In working as general designer, NIIEFA-ENERGO uses external subcontracting for the following work:

  • engineering survey;
  • design of overhead and cable lines;
  • water supply and drainage;
  • master plan and transport;
  • other special sections (environmental protection, electromagnetic compatibility, etc.)
