The Independent Power Transmission Operator (IPTO) on Wednesday again denied reports that the fire in the northern suburbs of Athens was started by an explosion in a high voltage power transformer.
According to official sources, such an explosion in IPTO installations would mean that the power lines knocked out by the fire on Tuesday could not have been repaired by the following morning.
They also stressed that an inspection of the network on Wednesday morning had shown that damage to the network was slight and of minor importance.
An investigation into the cause of the fire is being carried out by the fire brigade, the IPTO announcement added.
So far, the Fire Service has not made any announcement on the causes of the fire that broke out in the forest in the foothills of Mt Parnitha and several explosion were heard and seen.
