Sales on the domestic-commercial market recorded an increase of 9.2%, mainly because of the 23% increase in demand during the last four months of the year. In 2006, the demand from this market fell by 7.8% and, therefore, the initial situation favoured the increase.

In short, 13.8% of natural gas sales went to this market.

The historic high of the year was recorded on 12 December 2007 with a total demand of 1,716 GWh. Another three highs had been recorded previously on 22, 28 and 29 November.
