NEW YORK - Marathon Oil Corp began restarting its Robinson, Illinois oil refinery following a power outage Sunday afternoon after a small plane hit a power line feeding the refinery, a spokeswoman said on Tuesday.

A small plane hit a line that supplies the area, there was a small blip at the refinery and we began bringing it back again, spokeswoman Linda Casey said.

We began restarting immediately, as soon as the power came back, she added, but declined to specify if the complex was back to planned rates.

Casey had no further details about the incident.

The Robinson refinery has a total capacity to process about 204,000 barrels per day. (Reporting by Haitham Haddadin; Editing by John Picinich)
