Ukrainian Prime Minister Volodymyr Groysman has ordered to urgently settle the situation with a new mechanism for forming Ukrainian coal prices pegged to the coal price in Rotterdam port and transport fees introduced this spring by the National Commission for Energy, Housing and Utilities Services Regulation (NCER).

"I think that there are many unknown variables in this formula of the coal price, so-called Rotterdam plus formula… I talked to president about this, and the president is concerned about this issue too," he said, opening a government meeting in Kyiv on Friday.

"I believe that the government's position should be clear – to take the formula, understand what is going one and do everything to make it transparent and meeting the real price of coal in Ukraine and secure the formation of the realistic price of electricity," he added.

The prime minister instructed Deputy Prime Minister Volodymyr Kistion and Energy and Coal Industry Minister Ihor Nasalyk to attract the NCER and prepare an analysis of the steam coal price formula during one week.
