15 Development of EU-MENA transmission systems Development of new interconnection on South South axis DESERTEC as enabler coming before development and realization activity Main transmission target: Identify grid requirements for desert power Assess grid conditions Assess relevant transmission technologies Work out optimal transmission paths to relax bottlenecks Develop transmission cost model Develop scenarios for grid arrangements Examine the impact of transmission on EU/MENA Italian Operations Department- Investment Planning/Grid Planning 15

16 Development of EU-MENA transmission systems Development of new interconnection on South South axis MEDGRID foundation is a unique private industry joint venture aiming at creating a Trans- Mediterranean grid system for transmission of energy between MENA countries and with Europe. Target of Medgrid: Design in partnership with the MENA countries, the Mediterranean transmission grid Master Plan for 2020 Promote a regulatory and institutional framework Assess the benefits of investments in grid infrastructures Develop technical and technological cooperation with the MENA countries Promote HVDC technologies for power transmission Italian Operations Department- Investment Planning/Grid Planning 16

17 Technical challenges for the completion of the Mediterranean ring Growing interconnection around the Mediterranean Area UCTE block expanded to Southeastern Europe InterlinkagetoSW-Mediterraneanblock and recently also with Turkey on going HVDC Challenges for completion of Medring remain failed synchronisationattempts with SE-Mediterranean (Libya-Tunisia) Low capability of North African Countries to react to disturbances If synchronisation tests continue to fail, linking the systems through HVDC may be a possible option Italian Operations Department- Investment Planning/Grid Planning 17
