LONDON (Reuters) - Several units at Essar's 200,000 barrel per day Stanlow refinery in northwest England were shut down following a power outage earlier on Wednesday, a spokesman for the plant said.
"Earlier this morning the power supply... to Stanlow from the national grid failed. This has resulted in the shutdown of a number of units on site," the spokesman said in a statement.
The unplanned shutdown at the plant resulted in visible flaring. It was unclear how long the outage would last.
