Gazprom will send some of the gas from its controversial Nord Stream 2 pipeline through Slovakia, the Russian state-controlled company said, in a move that may soften Slovak opposition to the project.

Gazprom's gas sales in Europe in the first half of 2016 rose by 14.2%, or 10.6 Bcm, compared with the same period of last year, Gazprom CEO Alexei Miller said Thursday, signaling a sharp slowdown in export growth in the second quarter of this year.

Eustream said June 30 that it welcomed assurances from Gazprom at the meetings that the Slovak and the Czech gas transmission systems will be used in long term even if NS2 is built. Eustream said also it “highly appreciates the understanding between both parties that the entry point from Ukraine to Slovakia shall remain fully functional even if NS2 is commissioned.”

In 2015 Gazprom increased gas exports to the region by 8% compared with 159.4bn m³ in 2014. The latest official statistics also indicate that Gazprom's gas exports experienced significant growth in the first four months of 2016.

BP’s energy outlook this year foresees a compound annual growth rate of gas demand at 1.8% until 2035. In the OECD, this growth results from the coal-to-gas transition in power generation. The US major ExxonMobil supports this view, forecasting gas will account for 30% of the power sector and will equal coal by 2040.

It is absolutely compatible with the Energy Union. It will be sustainable, affordable and help security of supply, he said. It will increase liquidity in Europe but nobody will be forced to buy the gas, which will be priced against hubs.

"We have such low production costs that we will always be able to cut the selling price by a dollar or two when it comes to fighting off a rival," said a senior source at Gazprom.

"We are glad that we've managed to maintain our positions on traditional markets, primarily in Europe," Sechin said pointing out to recent agreements with PKN Orlen to increase deliveries to Poland and the Czech Republic.

Shipping 110bn m³/yr would cost Gazprom a quarter of the amount it would spend if it used Nord Stream, while booking capacity for 70bn m³/yr would still cost it only a third as much.

Gazprom's accumulated after-tax dividends will total USD 6.9 billion by 2045. Over the next 25 years, gas deliveries via Nord Stream 2 would be 2–2.7 times more economically efficient than the ones via Ukraine's GTS, which translates into USD 45–78 billion.
