For years, Gazprom has rejected any possibility of such a revision, and as a result, the contract price for PGNiG has significantly exceeded prices on Western European markets," the company's statement read.

In 2012, the prices were reduced by 10 percent, but in 2015 PGNiG filed a complaint with the Stockholm arbitration court demanding the new reduction of prices from Gazprom in line with the European gas market trends at that time.
