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 offer the TRU service quantity as a monthly service during the remaining pilot phase in the auctions in line with the following auction calendar:
