A group of detainees armed with “various weaponry” at the west London immigration centre caused the “disturbance” in the early hours of Saturday, the Home Office said.
No one was injured during the incident at Harmondsworth detention centre near Heathrow Airport, but the power was still out just before 9am on Saturday, according to the department.
Metropolitan Police officers attended the incident at 7.45pm on Friday and they are still at the scene, the force said.
A statement read: “There has been a power outage at Harmondsworth immigration removal centre, and work is currently under way to resolve this issue.
“The Metropolitan Police service and HM Prison Service are at the scene.”
A Home Office spokesman added: “A group of detainees left their rooms and went out into the courtyard area armed with various weaponry.”
“Territorial Support Police were sent to the scene, and the power is still off.”
They added that none of the detainees had left the premises, and they have since been returned to their rooms.
