Power back on in St Petersburg

4:16 pm on 21 August 2010

Electricity is back on after a huge power cut lasting about an hour in Russia's second city, St Petersburg.

The power went off at about 6.40pm local time (1440 GMT) on Friday after a substation failed, affecting most of the city and its suburbs. St Petersburg has 4.5 million inhabitants.

Water supplies were also switched off and the power cut left underground stations in the dark and trolley buses at a halt.

The Federal Power Grid Company said the causes of the power cut were being investigated.
