Uniper Seeks Permission to Close Key German Gas Storage Site

Uniper SE has requested approval to shut one of Germany’s largest gas storage sites after failing to meet mandatory targets for refilling the facility this year.

Breitbrunn — near the Austrian border and considered important for both countries’ gas buffers — will be decommissioned in early 2027 if Germany’s Federal Network Agency approves the plan. Uniper said it had to submit proof that shutting the site won’t adversely impact energy security in Germany or the European Union.
