8.3 Investments in Germany

(Eastern Area of the Region)

On 1 April 2016 the German TSOs submitted the Draft German Network Development Plan 2016) to the German national regulatory authority Bundesnetzagen- tur (BNetzA). In the Draft German Network Develop- ment Plan 2016 the German TSOs propose investments into the German gas transmission system of 4.4 billion € by 2026. These investments include 802km of new pipelines and 551 MW of additional compressor power. The major drivers for the investments are the requirements to adapt the German gas transmission system for the entry of additional H-gas replacing the declining indigenous L-gas production and the L-gas imports from the Netherlands (see Chapter 5.3). The Draft German Network Development Plan 2016 is based on a scenario frame- work which was consulted on in mid-2015 and formally acknowledged by BNetzA on 11 December 2015. In December 2016 BNetzA revised the scenario framework. Based on the revised scenario framework, the German TSOs are developing and consulting on a revised Draft German Network Development Plan 2016 in Q1 2017. The scenario framework for the German Network Development Plan 2016 describes two supply scenarios for additional H-gas quantities required due to the declining Dutch and German L-gas production under consideration of – among others – pro- jects described in the ENTSOG TYNDP 2015. Based on the shares defined in the scenario framework for the two supply scenarios, the following peak flow assump- tions were applied in the modelling of the Draft German Network Development Plan 2016 (see Table 8.1).

Table 8.1: Peak flow assumptions for the two supply scenarios Q.1 and Q.2 of the Draft German Network Development Plan 2016

The supply scenario Q.2 was derived by taking a limited share of additional capaci- ties from Nord Stream 2 into account, while the supply scenario Q.1 did not include this assumed additional capacity.
