Ramezani told the Panel of Prospect of Gas Industry in Next Half a Century that the deal is expect to prepare the condition for export and shipment of gas to West Europe.

Between January-July, flows totaled 66.52 Bcm, 16% higher than the cumulative total for the same period last year and 13% up on the previous record high for the January-July period of 58.73 Bcm from 2014.

The so-called TAP, which formally started construction in May, will run for 878 kilometers (550 miles) from Greece's border with Turkey, through Albania and to southern Italy, including a 105-kilometer (65-mile) stretch under the Adriatic Sea. First deliveries to Europe are expected in 2020.

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.
