Supply security
AGCS has implemented measures in the market rules to ensure supply with the aim of maintaining a
functioning balance group model and balancing energy market even in the event of bottlenecks.
The obligation to ensure supply security results from ยง 33b (5) fig 4 Gas Industry Act
according to which the balance group coordinator must take special measures if there are no offers
for balancing energy.
AGCS has developed concepts and products jointly with the system operator and the storage
facilities operators to manage bottlenecks and has also included these in the market rules.
Currently, the following bottleneck management measures are available:
- The re-opening of the tertiary control reserve market is possible at any time during office hours.
- Since the year 2005, the storage facilities operator OMV Gas GmbH has made available the product day-ahead rates; in the event of bottlenecks, storage facility operators make free capacities available for storage customers.
- Additionally, in the event bottlenecks, the possibility was created of offering structured and unstructured hourly block bids per fax in the tertiary control reserve market. Thus, balancing energy volumes from foreign storage facilities as well as foreign and domestic flexibility from consumer blackouts, possibly also flexibility from line pack capabilities, are made available to the tertiary control reserve market.
- The system operator is authorized to take the following measures if normal system control instruments and balancing energy management is not sufficient:
- Suspension of the sequence when calling tertiary control reserve bids from the Merit Order List (calling of bids depending on the geographic feed-in points);
- Simultaneous calling of bids for supply and demand.
