Value Chain Analysis Erneuerbare Energien Stuttgart (WZ D35): Wo der Mittelstand in der Metropolregion die Wertschöpfung verliert

Introduction: Stuttgart is known for automotive and engineering. But WZ D35 (Strom- und Wärmeversorgung) is undergoing a massive shift towards renewables. The Mittelstand in the Stadtkreis faces structural challenges.

Value Chain Analysis Framework applied: Primary Activities:

1. Inbound Logistics (Rohstoffe, Komponenten wie Wechselrichter, PV-Module, Windrotoren - meist aus Fernost oder Norddeutschland)
2. Operations (Erzeugung, Netzintegration, Speicherung - lokale Akteure vs. Großkonzerne wie EnBW)
3. Outbound Logistics (Netzbetrieb, Einspeisung, Direktvermarktung)
4. Marketing & Sales (B2B PPA, Endkunden-Tarife, Quartierskonzepte)
5. Service (Wartung, Repowering, Smart Meter Rollout)

Support Activities:

1. Firm Infrastructure (Genehmigungsverfahren in BaWü, Netzentgelte, Digitalisierung)
2. HR Management (Fachkräftemangel in BaWü, Ingenieure)
3. Technology Development (KI-gestützte Netzsteuerung, Batteriespeicher R&D)
4. Procurement (Einkauf von Grünstrom-Zertifikaten, Hardware)

Regional Depth: Stuttgart Stadtkreis: High energy demand, limited space for large-scale wind/solar within city limits. Dependence on surrounding regions (Neckar-Alb, Hohenlohe) and external grids. Key players: EnBW (HQ in Karlsruhe but strong in Stuttgart), Stadtwerke Stuttgart, regional Mittelständler like Erdgas Südwest (now part of EnBW) or smaller project developers. Comparison to other regions: Hamburg (Wind offshore focus, WZ D35 with strong municipal utilities like Hamburg Energie), Munich (SWM with large hydro and solar parks in Bavaria), Berlin (district heating transition). Stuttgart relies heavily on Daimler/PV on factory roofs and EnBW’s grid.

Strategic Recommendations:

• Vertical integration for Mittelstand (e.g., becoming a local aggregator).
• Partnerships with automotive suppliers shifting to energy tech.
• Exploiting the “Energiewende” in industrial estates (Stuttgart-Vaihingen, Feuerbach).
