At our company's Iwayato Power Station, it was discovered that the protective capacitors connected to the 11 kV electric circuit were electrical structures that used insulating oil containing high concentrations of PCBs. Based on the Electricity Business Act, we had decided to stop using electric facilities containing high concentrations of PCB by the end of March 2018. Because it was inappropriate, it continued to be used beyond the deadline stipulated by the ministerial ordinance.
