Thousands of homes are without power after a fault at an electricity sub-station.
Scottish Power said customers in and around areas of the north west of Glasgow were affected following a "technical problem" at its Windy Hills transmission station on Monday afternoon.
Residents in the Partick, Hyndland, Drumchapel, Bearsden and Milngavie areas were among those without power. The towns of Clydebank, Dumbarton and Helensburgh were also affected, as were some customers in Argyll.
