Open Grid Europe and astora agree on firm temperature-dependent transmission capacity for Haidach storage facility
Network expansion allows efficient storage use from 2020
Essen/ Kassel. Open Grid Europe GmbH (OGE) and astora GmbH & Co. KG (astora) have reached agreement on the provision of firm transmission capacity for the Haidach gas storage facility in Austria.
In 2013, astora initiated market abuse proceedings against OGE to assert a claim to the provision of firm transmission capacity. The Federal Network Agency decided that astora is basically entitled to firm transmission capacity for the Haidach storage facility, but the capacity may be made subject to conditions not specified by the Agency.
OGE and astora each filed an appeal against the Federal Network Agency's decision with Düsseldorf Higher Regional Court. The out-of-court settlement now reached means cessation of those appeal proceedings before the Düsseldorf court.
The key element of the settlement is OGE's obligation to provide firm temperature-dependent transmission capacity (TDC) for the Haidach storage facility as from 2020 on the basis of a longer-term TDC booking made by astora beforehand.
Storage customers in Haidach can, with the aid of TDC, use 100% of the booked transmission capacity for gas withdrawal if outdoor temperatures are 0°C or below. In a temperature range between 0°C and 8°C, 57% of the requested transmission capacity is still available on a firm basis.
During the summer, storage customers are guaranteed 100% of their firm transmission capacity for gas injection at temperatures from 16°C. At temperatures ranging from 10°C to 16°C, 22% of the requested transmission capacity is available on a firm basis.
The out-of-court settlement is an efficient and market-reflective solution for the Haidach storage facility. It takes account of seasonal fluctuations in storage use – both in the summer (injection) and in the winter (withdrawal) – and thus helps to achieve greater security of supply.
