ENTSOG GRIP CEE 2014-2023 / Main Report

The CEE countries have a significant sensitivity on gas supply disruption through Ukraine or Belarus. Therefore, the participating TSOs decided to prepare the regional N-1 analysis. The assessment is based on the capacities at IPs and resulting residual capacities for neighbouring countries through supply corridors within the region. The supply corridors and results for each country are described below. Compared to the previ- ous edition of the CEE GRIP the analysis was extended to a ten year period and the results for the winter periods 2014/2015, 2018/2019, 2022/2023 and the summer periods 2014, 2018 and 2023 are presented in this chapter.

5.1 Supply Corridors

5.1.1 Austria

The supply corridors on the following picture show the main supply corridor for Austria which is under normal condition through Ukraine and Slovakia through the IP Baumgarten (marked as AT1). Other supply corridors in case of supply disrup- tion through Ukraine, but also under normal conditions, are through Germany marked as AT2 and through Italy AT3. The remaining capacity that could be used for gas transmission to Slovakia, Hungary and Slovenia in a Ukraine disruption scenario was used as the input for the evaluation of regional N-1 calculation for Slovakia, Hungary and Slovenia correspondingly. In 2019 the start of operation of a new interconnector between Austria and the Czech Republic is envisaged.
