This was announced by the head of the GTS Sergey Makogon.

“The Ukrainian gas transmission system operator has submitted an application to the German energy regulator Bundesnetzagentur to participate in the certification procedure for Nord Stream 2 AG, the operator of Nord Stream 2,” he wrote on Facebook.

Makogon added that Ukraine "consistently continues to oppose the geopolitical project," RIA Novosti quoted him as saying.

The construction of the Nord Stream 2 gas pipeline was fully completed on 10 September.

The first line was filled with technical gas.

In early October, the Russian Foreign Ministry noted that the procedures for certification of the gas pipeline are underway, but it is difficult to foresee what "legal squiggles" could be used by opponents of this project.

On September 22, the Polish state-owned oil and gas company PGNiG received the right to participate in the certification procedure for the Nord Stream 2 operator by the German Federal Grid Agency.

According to PGNiG, the operator Nord Stream 2 AG does not meet the requirements.

Also, the application for participation in certification was submitted by the Ukrainian "Naftogaz".
