Large swathes of Falmouth, Penryn and Budock Water were left in darkness this lunchtime due to a massive power cut.
This is believed to have been caused by a 33,000-volt transformer catching fire in the area.
It resulted in the complete loss of electricity, telephones and even mobile internet.
Traffic lights in Penryn are also reported to have stopped working.
Falmouth town centre was out briefly, but power returned fairly quickly.
Other outlying areas were left in darkness for around 45 minutes.
