The company A. TRIANTAFILLIDIS ELECTRICITY APPLICATIONS S.A. was established in 1978 by the then Junior Electrical Engineer Alexandros Triantafillidis. The company initially undertook small projects, laying out the groundwork for its later well-established journey.  From the company’s beginnings, it made the most of Alexandros’s six-year experience in a large French electricity company.  Over the years, from the early 1980s, the company evolved into taking on larger construction sites and broadening its clientele. It was during this time that it undertook sites such as the LIDA MARIA residential complex in Thermi, Thessaloniki.
