PGNiG says gas flow from Ukraine should resume Wed

WARSAW, Jan 13 (Reuters) - Poland's dominant gas distributor PGNiG PGNI.WA expects gas flow from Ukraine to resume on Wednesday, a week after a Russian-Ukrainian price row cut deliveries to Europe, its spokesman said on Tuesday.

"We know from our unofficial sources that gas may flow tomorrow," Joanna Zakrzewska told Reuters. "We should know something more in a few hours."

A Reuters journalist at a Russian gas pumping station near the Ukrainian border said on Tuesday Russian transit gas had already started flowing into Ukraine.

PGNiG said earlier it had offset much of the shortfall in gas via Ukraine by increasing gas deliveries from a second pipeline crossing Belarus and also by tapping more extensively into Poland's domestic gas reserves.

The company also took steps to limit deliveries to its largest industrial clients, including top Polish chemical makers as well as the country's top oil refiner PKN (PKNA.WA) to help shield private households and public services from disruption.
