The EU-backed BRUA pipeline could suffer a major setback if the Romanian and Hungarian gas authorities approve a rulebook that would exclude key Austrian partners.

The Hungarian transmission system operator FGSZ took the European gas market by surprise on Friday when it announced it was no longer in a position to hold an open season on the Romanian-Hungarian-Austrian section of the pipeline.

Instead, FGSZ noted, the only ‘economically viable’ part of the Bulgaria-Hungary-Romania-Austria (BRUA) pipeline would be the existing Romania-Hungary interconnector, which could be expanded from its current capacity of 4.4 billion cubic metres (bcm) to 5.26bmc/year.

FGSZ said it had contacted the Romanian grid operator Transgaz with a view to conduct an open season procedure just on this point. The procedure would have an almost identical draft for the Romania-Hungary project only.

If the rulebook is approved by Romanian regulator ANRE, the original start date of commercial operations of 1 October 2022 would still apply, according to FGSZ.

ICIS understands that Romanian and Hungarian officials have until 1 August to approve the rulebook. If they fail to do so, the procedure has to start from scratch, but will then need to be in line with the European CAM network code.





Market surprise

A source close to the matter told ICIS that the announcement by the Hungarian grid operator FGSZ caught the market and counterparties by surprise.

“For the last three years of the process, Austria has been coordinating the Romania-Hungary-Austria (ROHUAT) project by organising legal workshops and putting that expertise to bring the project to ready level,” he said.

“Initially, the ROHUAT project would have ensured larger security of supply by connecting the Black Sea gas reserves into the European gas infrastructure. With this new development, the new source would be sacrificed and it would also limit upstream activity on new markets.

“I think the target group will also change with this shift in the direction of the project as the gas was initially aimed at western European hubs through the Baumgarten border point in Austria.

“I don’t know if there will be any project at the end.”

A source at the European Federation of Energy Traders (EFET) echoed the views, noting that the FGSZ statement was surprising, and stressed that the federation was following the matter closely.





Hijacked pipeline?

In its original form spearheaded by the EU, BRUA is expected to travel 582km south to north, linking Bulgaria to the central European Baumgarten hub in Austria.

It would include existing as well as new infrastructure, providing alternative supply and a new route that would help the region to wean itself off Russian gas.

Natural gas could come either from the Black Sea, or from the Caspian region when the new volumes come on-stream by the end of the decade.

However, if Austria is squeezed out of the project, the natural gas could be fed to other regional countries.

According to FGSZ the gas could be exported to Slovakia, Ukraine, Serbia and Croatia. The capacities of the Slovak interconnector is 1.75bcm/year, the Ukrainian pipeline 6.10bcm/year, 4.81bcm/year for the Serbian connection and 2.62bcm/year for Croatia.

If the rulebook is approved and the gas is not shipped to Austria, companies which expect to export the Black Sea gas, including the US ExxonMobil, or Austria’s OMV could be locked out of regional exports.

Instead, Russia’s Gazprom may be able to use the existing infrastructure to sell Russian gas to the region. This is because Russia is in the process of building TurkStream, a pipeline that would cross the Black Sea.

Construction works have already started on the first string which will supply the Turkish market.

Gazprom said in February it had also started building the offshore section of the second string, which could connect with the existing onshore infrastructure in Bulgaria.
