ATERMON was established in Athens in 1973 and its original scope of works pertained to the construction and maintenance of transmission and distribution lines of electricity.

These projects allowed ATERMON to acquire considerable technical know-how, but more importantly an efficient project management method and organization structure.

Armored thus, ATERMON expanded its scope and its expertise in the highly demanding sectors of Industry, Energy and Infrastructure.


ATERMON has successfully carried out, within strict time frames, projects of a complex technical nature and of high quality standards, such as:

  • The study, procurement, pre-construction, construction and commissioning of piping networks, high and low pressure in power stations and refineries
  • The integrated electromechanical construction of heat recovery boilers (HRSGs) in power plants
  • The integrated electromechanical installation of gas turbines (GT), steam turbines (ST) and generators in power stations
  • The complete installation of overhead and underground electrical transmission (150kV & 400kV) and distribution (6.3kV & 20kV) networks in mainland Greece and the islands
  • The supply, installation and commissioning of D.E.H.'s electricity generation units. fueled by oil, in a number of Greek islands
  • The installation of several kilometers of medium and low pressure natural gas pipeline networks of DEPA
  • The installation of Signaling and Remote Control systems in the railway network of the O.S.E
  • The construction of integrated sectors of the electrification of the railway networks of the O.S.E
  • The installation of A.P.E. units (wind/photovoltaic parks and hydroelectric plants).


ATERMON was among the first companies in the region to adopt quality control and quality management strategies as well as environmental policies.
The recognition of ATERMON’s dedication to the satisfaction of the Customer’s requirements led to long time partnerships and collaborations, branding thus ATERMON as the reliable choice in demanding technical projects.
Always open to innovative developments ATERMON started constructing large scale wind parks upon the turn of the millennium. Ever since, it has acquired significant experience in the construction of renewable energy projects (wind parks, hydro power plants and photovoltaic stations).
ATERMON has adopted high end technologies and owns considerable mechanical equipment. However, ATERMON is much more than these. It is a company defined by its people. Our entire personnel consisting of engineers, managers, experts in various fields, support and administrative employees, as well as the labor force are dedicated, focused and trained in quality, safety and good performance.
