KIEV, May 25 - Metinvest Group's Avdiyivka coking and chemical plant, Europe's largest enterprise in its sector, has started to work at full capacity for the first time in three years of Donbas hostilities after new high voltage power lines have been built.

Avdiyivka coke plant's eighth coke-oven battery delivered produce on May 24, Metinvest said in a statement.

Intensive shelling in August 2014 cut the plant off the power grids and it had to suspend production. Due to a sharp temperature drop, the refractory masonry of coke-oven battery No. 8 was damaged. The plant's workers managed to repair it on their own, however, irregular power supply did not allow the unit to be put into operation for a long time.
