The story
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 operated the İzmir trolleybus system, which lasted from 1954 to 1992. 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. İZSU Company was formed on March 25, 1987 to operate all water facilities in İzmir and on July 1, 1987 ESHOT turned over all water operations to İZSU. On September 1, 1994, the Coal gas factory in Alsancak closed down, leaving ESHOT only in-charge of city bus operations.
