The story

In 2006, investigations were begun by ENTSO-E, the European Network of Transmission System Operators, into the technical conditions for the interconnection of the national grid of Turkey to the continental European power system. A trial period of interconnection commenced on 18 September 2010, and after the signing of long term agreements, the interconnection with Europe became a permanent arrangement.

There was a nationwide blackout in 2015.
