  • From the proclamation of Turkish Republic in 1923 until today, Turkish electricity sector has undergone very important physical developments and structural changes. In order to abolish dispersed structure in power sector and provide operational integration, Turkish Electricity Association (TEK) was established in 1970 and generation, transmission, distribution and selling services were incorporated nationwide in TEK, except duty areas of privileged companies and municipal boundaries.

  • In 1993, for the purpose of maintaining transmission service in more active, productive and modern manner and within the scope of privatisation policies, TEK was unbundled into two separate state economic enterprises: Turkish Electricity Generation-Transmission Co. (TEAŞ) and Turkish Distribution Co. (TEDAŞ)
