Sioufas told reporters that Greek consumers, both private and businesses, were responding positively so far to ministry directives on the use of energy.

According to energy market sources, three electricity production stations were shut down on Monday due to technical problems, but the country's electricity grid continued operating smoothly helped by increased imports of electricity, and minor cutbacks in electricity to major consumers.

Sioufas said ministry agencies would remain on alert for the next two days due to rising temperatures in the country.

The country witnessed a large-scale blackout last year, just days before the opening of the Athens Olympic Games, which has prompted the government to review the power supply system in the country.
