HVDC back-to-back Georgia Turkey Interconnector, Georgia
The main Georgian 500 kV transmission system was extended by two new 500 kV links from Gardabani and Zestafoni substations to a new 500/400/200 kV substation near the Turkish border at Akhaltsikhe. The Akhaltsikhe substation was connected to the Turkish EHV grid at Borçka asynchronously using two back-to-back high voltage direct current links at Akhaltsikhe and a 400 kV overhead transmission line to the Turkish border.
