• Kollsnes gas processing plant shut due to power outage
• Unclear how long disruption will last
• Electricity supply to Troll A gas platform down

OSLO, April 3 (Reuters) - Equinor (EQNR.OL) , opens new tab said on Thursday it had shut down Norway's Kollsnes gas processing plant due to a power outage, with the offshore Troll A platform also losing its electricity supply, reducing natural gas exports to Europe.

The Kollsnes plant is one of Norway's biggest energy export facilities with a daily capacity to process 158 million cubic metres of natural gas, according to the plant's owner Gassco.

The incident at Kollsnes is so far expected to curb Thursday's gas processing capacity by 39 million cubic metres, Gassco's transparency website showed, although volume estimates may change.

"We have had a power outage at Kollsnes which has resulted in a controlled shutdown of the facility. We are evacuating the facility for personnel," Equinor said in a statement.

Gassco confirmed that Kollsnes had suffered a power cut, and said its procedures mandated an evacuation of the plant.

"The duration of the outage is uncertain," a Gassco spokesperson said.

It was not immediately clear what had caused the outage.

Separately, Gassco posted a message via power exchange Nord Pool that electricity supply to the Troll A gas platform, which is powered via a cable from land, was also down.

Norway became Europe's largest supplier of natural gas following Russia's full-scale invasion of Ukraine in 2022, providing about 30% of all gas imports to the European Union.
