The French government will likely authorize utility GDF Suez (GSZ.FR) to implement three increases of natural gas retail prices during the summer, newspaper Le Parisien reported Friday.

First, the French energy regulator is likely to approve a 4.5% price increase as part of the review carried out each quarter to adjust sales prices to GDF Suez supply costs.

Another increase, of about 2%, will be implemented to take into account rising transportation costs, the newspaper said.

A third increase, which would be as high as 4.4%, would be related to a court decision expected on a case brought by GDF against a freeze imposed by the government on gas price in 2011.
