KYIV, Jan 3 (Reuters) - Ukraine's government plans to accelerate the country's transition to clean and green energy as it tries to strengthen the national power network against Russian attacks, Prime Minister Denys Shmyhal said on Tuesday.

Ukraine, which was invaded by Russian forces last February, faces an energy shortage and blackouts following Russian missile and drone strikes which Ukrainian officials say have damaged about 40% of the national energy infrastructure.

"Plans for the decarbonisation of energy and the green transformation remain relevant. The war has made these challenges even more urgent," Shmyhal told a government meeting.

"We will use the potential of renewable energy - solar, wind, hydrogen generation, hydrogen technologies - more actively. The Russian attacks push us towards fundamental reform — building a decentralised energy system. It will be less vulnerable to enemy attacks."

Shmyhal said creating the conditions to build mini-electricity stations and small generating facilities would be a priority this year.

The government is also focused on repairing damage and strengthening security at energy facilities, especially at nuclear power plants, he said.

Industry experts say Ukrainian solar plants see their power generation falling in winter, and that the clean power sector has experienced significant destruction during 10 months of war.

Energy Minister German Galushchenko said in October that up to about 50% of Ukraine's solar energy facilities, and about 90% of wind farms, were out of service because they had been damaged during the war or occupied by Russian forces. (Reporting by Olena Harmash, Editing by Timothy Heritage)
