Power outage temporarily shuts down Adelaide's IKEA A POWER outage forced Adelaide's IKEA store to close for several hours this afternoon. A customer who contacted The Sunday Mail said the bulk of the Swedish retailer's power went out about 12.45pm and only cash registers and some emergency lighting were working. He said shoppers were herded into the bottom-floor market area and the busy Saturday crowd was "calm and orderly" and left the store quickly. An IKEA spokeswoman said the power outage caused by an external source and that customers were allowed back inside just before 2pm when full-power returned.
