Ukrainian Prime Minister Arseniy Yatseniuk has instructed the State Fiscal Service, the Interior Ministry, the Ministry of Energy and Coal Industry to check the situation with the purchase of transformer equipment by Ukrenergo.

"As I understand, Russian oligarchs have once again decided to improve their welfare at the expense of the Ukrainian budget... This [Ukrenergo's refusal to make advance payments for the purchase of transformers after the first stage of the tender] seems to be on hand to Russian "almost oligarch" Grigorishin, who is the owner of Zaporizhtransformator," his press service said.

As reported, Minister of Energy and Coal Industry Volodymyr Demchyshyn rejects the allegations of abuse in the tender for the supply of transformers for Ukrenergo.

Reports have recently appeared in mass media that Ukrenergo refused to make prepayments during the purchase of 22 transformers, while this significantly changes conditions for participants in the relevant tender, especially for foreign suppliers.
