And most importantly, how often it happened in the past,” added the Naftogaz CEO. As UNIAN reported earlier, on Marcch 1, 2019, Ukraine switched to a daily balancing of the gas market, which meets the requirements of the Third Energy Package of the European Union. In late December 2018, the energy regulator in Ukraine (NEURC) once again postponed the launch of daily gas balancing from December 1 to March 1, 2019. Prior to that, at the end of September, the launch was postponed from October 1 to December 1, 2018. In November 2018, Naftogaz accused regional gas distribution companies of sabotaging the implementation of the daily balancing of the gas market.
