The 400 kV Sakar power line, which forms the second link between the Bulgarian and Turkish power grids, has been formally commissioned.

The new link, with a maximum capacity of 700 MW, was built under a long-term agreement on electricity export between Bulgarian electricity supplier NEK and the Turkish energy company TAES. The 150 km line (of which 60 km are on the Bulgarian side and 90 km on the Turkish side) runs from Maritsa Iztok 3 in Bulgaria to Hamitabat.

The first link between Bulgaria and Turkey was the 400 kV Edirne power line from Maritsa Iztok 3 to the Babaeski plant in Turkey.
