Pilot phase 2018/2019

The Trading Region Upgrade (TRU) service is a new specially designed service to connect the Austrian and the Czech gas markets directly. The service is provided by the Austrian and the Czech Transmission System Operators Gas Connect Austria and NET4GAS.

As of 01 October 2018, 06:00 CE(S)T, TRU entitles network users, who have succeeded in the TRU auction, to send an exit nomination from the Czech market area which is immediately matched with entry into the Austrian Market Area East, and vice versa.

Within the scope of the 1-year pilot phase, the TRU service has been offered first as a yearly service with a quantity of 112,686 kWh/h out of which 90,000 kWh/h has been sold in the direction from the Czech Republic to Austria.

Following this, the TRU service has been offered in form of quarterly auctions. In the 1st quarterly auction, a quantity of 22,000 kWh/h was sold from the Czech Republic to Austria for the second and third quarter of 2019.

Gas Connect Austria and NET4GAS will during the pilot phase offer the remaining TRU service quantity as quarterly and monthly service in the auctions in line with the auction calendar available below.

As of 31 October 2018 Gas Connect Austria and NET4GAS offer the TRU service additionally on day-ahead basis via the PRISMA booking platform.
