Shell sells Sonnen to Tiven and Aurelius Water Rise

Type: Sale · Technology: Storage · Country: Germany · Announced: 2026-08-31

Shell completed the sale of its fully owned subsidiary Sonnen, a residential battery storage systems manufacturer, to Tiven and Aurelius Water Rise. The transaction was first reported by Handelsblatt and later confirmed by Shell, though no official announcement was made by the companies. Tiven, an international asset manager and family office led by Gert Purkert, plans to restructure Sonnen with the aim of preparing it for a future resale. The purchase price was reported to be in the low hundreds of millions of euros, significantly below Shell's acquisition price of approximately €500 million in 2019. Sonnen has faced financial challenges in recent years, prompting Shell to inject additional capital in 2024 to sustain operations.
