"For the purpose of the plants' construction during Yanukovych era, their [Kliuievs' - ed.] companies were receiving land plots, and equipment for the plants had been imported without taxes and VAT," the reported noted.
Shcherbyna wrote that many capacities of the Kliuievs' solar power stations remained in the annexed Crimea, "but, as media reported, those stations that were left at the mainland had received nearly 3 bln UAH from the state "Enerhorynok" enterprise by the end of 2014.
"Back in 2014, the Cabinet enacted a regulation offering to lower the 'green tariff,' which was done. Later, in July 2015, the Verkhovna Rada also decided to lower to the rates for solar power stations," the reporter added.
However, according to Shcherbyna, Kliuievs' companies are currently suing the Cabinet, attempting to collect money back from the state, saying the lowering of the 'green tariff' was unlawful. The sum in question reaches 83 mln UAH, the reporter informed.
The 'green tariff' lowering has been also criticized by legal firm Arzinger, which was connected to Kurchenko and Rosneft by another People's Front MP Tetiana Chornovol.
"Back in 2011, Arzinger posted on their website that they were consulting a company owning a park of solar power stations in Ukraine. If my understanding is correct, the Kliuiev's company was meant," Shcherbyna wrote.
