Almost all units at Lukoil's Burgas refinery are running normally again after a fault in the power grid, the company said. Normal operation was restored early this morning.
On Monday, 9 November, a short circuit at the Kameno substation disrupted part of the plant's production units. Output at the refinery fell for a time. The company said it acted at once.

The catalytic cracking unit is not yet fully back. Technicians are still working on it to return it to normal operation.
Lukoil says stocks at the refinery are enough to meet Bulgaria's need for oil products, and deliveries and shipments are running on schedule.
The company also said the incident did not breach environmental limits, including those for air quality.
