Project name: Austria – Italy interconnection between Wurmlach (AT) and Somplago (IT), Project of Common Interest (PCI) n° 3.4.
Project promoter: Alpe Adria Energia Srl, (AAE) an Italian Company headquartered in Udine, fully owned by Enel Produzione S.p.A (Energy sector).
The project concerns 220kV a.c., 300 MW merchant line between Italy and Austria.
The project was implemented in the framework of the European Regulation 714/09 that allows private enterprises to build new electrical interconnection lines and to use the new capacity, in order to strengthen competitiveness of the European energy markets and to increase the crossborder capacity among Member Countries.
Also for the above mentioned reason the project is necessary from energy policy perspective. Considering that Italian-Austrian border results congested, this interconnection allows to increase directly of 300 MW the grid transfer capability of the border, it will have a positive impact on energy system-wide generation and it will be a tool for the competiveness of the systems due the possibility to dispatch the energy produced by the more efficient Power Plants and RES, assuring no additional costs for citizens. Although the investment will be borne by the project promoter and not repaid in the bill by end customers, since the entry into operation, the line will become part of the national transmission grid and contribute to market integration.
AAE is evaluating the best technical solution by using an underground cable, maintaining the previous electrical nodes (Somplago, municipality of Cavazzo Carnico - Italy and Weidenburg, municipality of Wűrmlach - Austria) and the involvement of other project promoters on same borders with the aim to define effective amendments to the Project, in order to satisfy the requests of the local entities involved as well as the Friuli Venezia Giulia Regional Energy Plan (PER) indications.
The project is included in the TYNDP 2016 of the ENTSO-E and in the first list of Project of Common Interest (PCI) 2013/2015 and the second PCI list 2016/2017 issues by European Commission in the framework of the Regulation EC/347/2013.
In addition the project is included in the preliminary third list PCI.
The main benefits of the project are:
Greater security of supply and interchange with foreign countries, thanks to the new transit capacity of the AAE interconnection that could double the present net transfer capacity between Italy and Austria;
Improved quality, safety and reliability of the interconnected electricity systems, by reducing the risk of congestion and power surges;
Integration of renewables and accommodation of flows;
Access to cheap energy and increase the use of more efficient production, resulting in a positive impact on the energy price.
