DAVOS, Jan 25 – Naftogaz Ukrayiny will publically present its plan to unbundle gas transportation and production operations in early February, Naftogaz CEO Andriy Kobolev said in Davos.

"The option that we consider the most realistic for us of all now available in relation to parliament's work, politics and everything else is concession. The concession fits into the ISO (Independent System Operator) unbundling model that we need to maintain, including our requirements," Kobolev told Interfax-Ukraine on the sidelines of the Ukrainian Breakfast organized by the Victor Pinchuk Foundation.
