Breitbrunn

Bavarian depleted-field gas storage run by NAFTA Speicher, exempt from Germany's reduced 45% fill target.

Breitbrunn occupies a former exhausted gas field in Bavaria, owned by NAFTA Speicher with Uniper Energy Storage running it as storage system operator; it meets the standard 80% fill target for 1 November, unlike six named pore sites.

Background

Breitbrunn, also known as Breitbrunn/Eggstätt, reuses a depleted natural gas field to hold injected volumes, with NAFTA Speicher as owner and technical operator while Uniper Energy Storage acts as storage system operator, a split of roles not uncommon in the German market. It sits within NAFTA's three-site Bavarian portfolio, alongside Inzenham-West and Wolfersberg, whose combined working gas capacity runs to around 1.8 billion cubic metres.

Bavarian sites like Breitbrunn fall outside the six pore-storage facilities singled out for relief, so the Gasspeicherfüllstandsverordnung holds it to the standard 80% target for 1 November.
