KYIV, Nov 17 – Ukraine needs to implement a number of projects in the next five or 10 years to increase the capacity and flexibility of the energy system, the volume of investments in which will be about $15 billion, Board Chairman of Ukrenergo Volodymyr Kudrytsky has said.

"There will be countless more winters to go through. And our crazy neighbor isn't going anywhere. Therefore, we need to think not only about this winter, but also about the future. Therefore, we, as the system operator, have a calculated vision of what the optimal energy mix of our country for five-seven-ten years, what we must build to protect our facilities from heavy shelling, and also to make the energy mix cheaper and cleaner. There is a certain investment menu," Kudrytsky said at a briefing at the Media Center in Kyiv on Friday.
