A brake on gas prices currently being discussed by the German government could cost between 15 billion and 24 billion euros, depending on market price developments, the Handelsblatt business daily reported on Thursday.
The range, based on an estimate by the government's expert gas commission, is based on the measure applying only to private households, according to the report.
A gas price cap, another measure being considered to curb skyrocketing gas prices in Germany, would come in at a similar cost, it added.
