What Oekorenta does

ÖKORENTA Gruppe is a privately held German investment company founded in 1999 and headquartered in Aurich, East Frisia, that issues, distributes, and manages closed-end portfolio funds investing in European renewable energy infrastructure — primarily wind parks, solar parks, and battery storage solutions. The group operates through a vertically integrated structure comprising Auricher Werte GmbH, its BaFin-licensed Kapitalverwaltungsgesellschaft (approved April 2018); ÖKORENTA FINANZ GmbH for fund distribution; SG-Treuhand GmbH for trustee and investor services; and an in-house Betriebsführung unit providing commercial and technical management of renewable energy plants. Since launching its first fund in 2005, the group has issued 32 fund vintages across two main product series — the public Erneuerbare Energien funds (€5,000 minimum) and the ÖKOstabil S-AIF range for professional and semi-professional investors — and has added a Spezialmandate tier (€3 million minimum) for institutional investors and family offices.

The firm is 100% founder-controlled by Tjark Goldenstein, who chairs the supervisory board of Auricher Werte GmbH, and operates with 59 employees across Aurich, Leer, and Kirchheim bei München. Its revenue model is built on recurring fund management fees, capital administration services for alternative investment funds, and transactional placement economics on new fund emissions, with pricing ranging from €5,000 (retail) to €3 million (institutional mandates). Distribution combines an internal sales entity, a network of third-party distribution partners, and a self-serve investor portal. ÖKORENTA differentiates itself through its BaFin-regulated in-house KVG, its early adoption of Article 9 status under the EU Taxonomy (ÖKORENTA Erneuerbare Energien 14, 2022), and a proprietary ESG due diligence and CO2 savings calculation methodology that anchors at least 80% of fund capital to sustainable assets. The company is bootstrapped, with no external private equity or venture capital disclosed.

Direct peers

• Encavis AG: Hamburg-based wind and solar park operator/asset manager that has expanded into fund products for institutional investors, overlapping with ÖKORENTA's wind/solar/storage infrastructure thesis and German-DACH focus.
• KGAL (KGAL GmbH & Co. KG): Munich-based asset and investment manager focused on long-term real asset investments including renewable energy infrastructure funds for institutional and private investors — directly competes for the same institutional renewable energy capital pool.
• LHI Group: German investment manager specializing in real assets and infrastructure funds (renewable energy, real estate, aircraft), with closed-end fund structures and institutional mandates — directly comparable business model to ÖKORENTA's renewable energy fund platform.

Broad incumbents

• DWS Group: Global asset manager with a growing European infrastructure and renewable energy platform (e.g., DWS Grundbesitz, Xtrackers ESG range) — competes in institutional and retail sustainable infrastructure distribution.
• Union Investment: One of Germany's largest asset managers, with growing sustainable infrastructure and Article 9 fund offerings — a scaled competitor with significantly broader distribution into retail and institutional channels.
• Commerz Real (Commerzbank Group): Large German KVG/asset manager with infrastructure and renewable energy mandates within a broader real assets and digital infrastructure portfolio — competes for institutional sustainable infrastructure capital at greater scale.
• HANSAINVEST Hanseatische Investment-GmbH: Major German KVG offering a wide product range including sustainable and infrastructure funds — competes for distribution partner shelf space and institutional mandates in the renewable energy category.

Emerging players

• ÖKOWORLD AG: German ecological investment fund manager focused on sustainability themes with a smaller, more thematic product range — competes for ESG-oriented retail capital with a more concentrated equity-selection approach.

Others

• ABO Wind AG: German wind and solar project developer that increasingly structures its own fund vehicles — adjacent to ÖKORENTA as a project originator, and a potential project pipeline source for ÖKORENTA's Ankauf team.
• ENERTRAG AG: German renewable energy company active in wind project development, operations, and hybrid storage solutions — adjacent ecosystem participant whose projects and operational expertise overlap with ÖKORENTA's investment universe.
