In 1999, Industrial Design and Construction Association "TADES" State Company "Barki Tojik" was transformed into open joint stock company Design - Industrial - Construction Association "TADES", which is the main link of self-supporting management of grid construction in the Republic of Tajikistan and is a single production and economic complex. During the years of its existence JSC BPO "TADES" actively participated in all significant construction projects of the republic: SS "Tavildara," 35 kV overhead line "USSR-India" for direct connection of overhead lines of 110 kV between substation "Nurek" and Substation "Tutkaul" electricity Kunduz Islamic State of Afghanistan, the memorial complex "Somoni" and others. In addition to specific goals and objectives for the construction, reconstruction and rehabilitation of power facilities in the period 1985-2000years. JSC BPO "TADES" carries huge volumes of construction and repair work on the most important economic building sites. In 2004, a change of organizational form BPO JSC "TADES" enterprise becomes closed joint stock company. In addition, the company includes in its membership Joint Venture Limited Liability Company "TADES International". CEPA "TADES International" has participated in various tenders announced by the Centre for implementation of the international credit organizations, has experience in the conclusion of such major contracts as "Replacement of pipes siphon" Shurchasay "Khatlon", "Rehabilitation of the Grand Canal in Hissar Lenin"," Emergency measures for stabilizing landslide Baipaza "and others.
