Black Sea Transmission Network
The Black Sea Transmission Network is a project for electric power transmission from Georgia to Turkey. Technical descriptionThe project foresees a rehabilitation and expansion of the existing transmission system. An overhead transmission line with a total length of 247 kilometres (153 mi) will be built from the existing Gardabani and Zestaponi substations to the new Akhaltsikhe substation situated at 41°42′26″N 43°06′35″E / 41.70722°N 43.10972°E. The line between Gardabani and Akhaltsikhe will be 187 kilometres (116 mi), of which 86 kilometres (53 mi) is a rehabilitation of the existing line and 101 kilometres (63 mi) will be a new line. The line between Zestaponi and Akhaltsikhe is 59 kilometres (37 mi) long, of which 35 kilometres (22 mi) is a rehabilitation of the existing line and 24 kilometres (15 mi) will be a new line. The 500 kV overhead line will be a single-circuit transmission line.[1] At Akhaltsikhe substation two back-to-back high-voltage direct current stations, each with a capacity of 350 MW will be installed. A 400 kV AC overhead line will connect it with Borçka substation in Turkey. About 35 kilometres (22 mi) of it will run in the territory of Georgia.[1] The first HVDC back-to-back station would be operational in May 2012 and the second one in May 2013. This link will be built by Siemens.[2][3] FinancingThe project is financed by several European finance institutions. The European Investment Bank and the European Bank for Reconstruction and Development lend €80 million both while the German development bank KfW provides €100 million in the form of a grant (€25 million) and a long-term loan (€75 million, €20 million Development Bank of Austria, w:de:Oesterreichische Entwicklungsbank (OeEB) risk participation).[4][5] The project is developed by the Georgian state-owned transmission system operator Energotrans.[2][3] See alsoReferences
