WindStrom

What WindStrom does

WindStrom Erneuerbare Energien GmbH & Co. KG, headquartered in Edemissen, Lower Saxony, is a privately held German wind energy project developer and operator founded in 1992. The company plans, builds, and operates wind farms across Germany and selected European markets (France, Poland, Italy), with a realized reference portfolio of approximately 495 wind turbines totaling 1,164 MW. The legal structure is a GmbH & Co. KG (limited partnership), with WindStrom Projekt GmbH as general partner and additional wholly owned subsidiaries covering service operations (WindStrom Service und Betriebsführungs GmbH), wind park administration (WindStrom Windpark Verwaltungs GmbH), solar development (WinWin Solar GmbH), and international operations (WindStrom Polska Energia Innowacyjna Sp. z o. o and WindStrom France SAS). The company is owner-managed by Managing Directors Steffen Warneboldt (co-owner since 2001), Christoph Schramke, and Thomas Uhlmann, and employed approximately 80 people as of March 2026.

The service portfolio spans the full wind park lifecycle: project development and repowering (site identification, wind potential assessment, BImSchG permitting); commercial project management (profitability calculations, financing, equity raising, citizen participation); grid connection planning and substation construction; construction management and commissioning; commercial operations management (bookkeeping, feed-in tariff billing, liquidity planning); and technical operations management delivered through a strategic partnership with ENERTRAG Betrieb GmbH (which provides 24/7 remote monitoring, condition monitoring, and compliance inspections for over 1,100 wind turbines). Go-to-market is sales-led and partnership-based: direct outreach to landowners, municipalities, and project partners; industry trade shows (WindEnergy Hamburg, Husum Wind); and community engagement through wind festivals and Bürgerwindpark (citizen wind farm) models.

Revenue derives from a mix of project development and construction management fees (project-based), recurring commercial and technical operations management fees (managed services, retained across the wind farm's operating life), and transaction-fee income from citizen participation investments. Key enterprise relationships include enercity Erneuerbare as a joint development partner (Windpark Münstedt, €75M, 44.8 MW) and ENERTRAG Betrieb GmbH as the technical operating partner. There is no publicly disclosed revenue, no external institutional or venture capital backing evident in the data, and no AI/ML capabilities disclosed.
