German Economy Minister Robert Habeck said on Friday that it was "more than unsatisfactory" that profitable companies could also access a gas levy on consumers meant to help troubled firms and was looking at possibilities to change it, Trend reports with reference to Reuters.
However, abolishing the levy is not an alternative, he said, adding that any changes to the levy must not endanger the country's energy supply.
He also warned that the country is heading for a jump in energy prices come winter that will make the current increase look small.
