Before ESHOT was formed, all of İzmir's public services were operated by several companies. ESHOT Genel Müdürlüğü was formed on July 27, 1943 to take over the İzmir Tram and Electric Company. This company operated all trams, trolleybuses and electric facilities in the city. In 1945, ESHOT took over the İzmir Coal Gas Company and on June 5, 1947 ESHOT took over the İzmir Suları A.Ş. to have control over all the cities main facilities. ESHOT started printing their own paper on June 11, 1957 for new information on all public utilities. By 1959, ESHOT began producing refurbished buses under the direction of Ismail Faruk Paksoy, director of Eshot. In the 1960s the Kordon trolley line was abandoned. ESHOT started operating province wide starting December 11, 1980. On September 12, 1982 the Turkish Electric Company took over all electric operations from ESHOT. The İzmir Municipality became the parent company of ESHOT on June 27, 1984.
