Wi IPP

What Wi IPP does

Wi IPP GmbH & Co. KG is a German independent power producer (IPP) that acquires, owns, and operates wind energy and photovoltaic (PV) installations, with a strategic emphasis on repowering existing wind sites with modern high-capacity turbines. Founded in 2016 by Matthias Willenbacher as part of the wi renewables group, the company operates 65 wind turbines and 48 solar installations across Germany with combined generating capacity exceeding 180 MW, primarily concentrated in Rhineland-Palatinate with planned expansion into Mecklenburg-Vorpommern. Notable technical programs include the Mehringer Höhe repowering (replacing 14 older turbines with 7 new Enercon E-138 units, tripling annual output to 110,500 MWh) and the Nordpfälzer Bergland repowering (replacing 1.8 MW E-66 units with 4.26 MW E-138 turbines). The company is also piloting agrivoltaics at its Schneebergerhof site, combining greenhouse agriculture with solar PV and planned battery storage.

Wi IPP generates revenue primarily by selling electricity from its assets to the public grid under Germany's EEG feed-in tariff regime, which provides typically 20-year guaranteed revenue streams, with additional income from direct marketing and Power Purchase Agreements (PPAs) once EEG periods expire. The company's secondary but strategically critical revenue model is capital raising through retail-investor bonds and crowdinvesting products issued via partner platforms WIWIN (German retail) and Inyova (Swiss retail), plus institutional Special AIF structures distributed through Dr. Peters Group. Bond interest rates range from 4.00% to 6.00% annually plus bonus components, with minimum investments as low as EUR 100.

The company sells its investment products to private investors, semi-professional investors, and institutional investors, with a distinct emphasis on regional citizen participation (Bürgerbeteiligung) to build social acceptance for renewable energy projects near its wind and solar parks. Operational and management oversight is provided by the wiwi Beteiligungs GmbH (the general partner of the KG structure), with Managing Directors Matthias Willenbacher and Daniel Güttinger. Wi IPP disclosed approximately EUR 7 million in revenue for fiscal year 2024 and operates with a small team (11-50 employees), relying on its integrated wi renewables ecosystem (wiwi consult for project development, WIWIN for distribution, WITURA for sustainable real estate) to source, develop, and finance its asset pipeline.

Revenue model

1. Electricity Sales via EEG Feed-in Tariffs: Wi IPP sells electricity generated by its 65 wind turbines and 48 solar installations to the public grid under Germany's Renewable Energy Sources Act (EEG). Feed-in tariffs are guaranteed for typically 20 years from commissioning, providing predictable, long-term revenue. This is the foundational revenue stream supporting bond interest payments and investor returns.
2. Direct Marketing / Power Purchase Agreements (PPAs): After EEG subsidy periods expire or for new projects without EEG entitlement, Wi IPP markets electricity through direct sales contracts with utilities, direct marketers, and corporate customers via long-term Power Purchase Agreements (PPAs). PPAs provide price certainty and enable sales at current market rates or agreed fixed prices.
3. Bond Issuances and Crowdinvestment Capital Raising: Wi IPP raises growth capital by issuing bonds (Anleihen) and short-term notes (Kurzanleihen) to retail and institutional investors via platforms like WIWIN and Inyova. Interest rates range from 4.00% to 6.00% annually plus bonus components, with terms from 6 months to 7 years. Capital funds specific project acquisitions, repowering, and portfolio expansion.

Direct peers

• PNE AG: PNE AG develops and operates wind and solar farms in Germany and internationally, with both project development and IPP operations. Its onshore wind focus, German regulatory exposure, and crowd-investment history make it a direct peer.
• Encavis AG: Encavis is a leading European Independent Power Producer (IPP) operating utility-scale solar and onshore wind farms across multiple European countries. It is the closest scale and business-model comparable to Wi IPP, with similar long-term cash flow profiles and institutional funding structures.
• ABO Wind AG: ABO Wind is a German renewable energy developer and operator specializing in wind and solar projects. It combines project development (analogous to wiwi consult) with asset operation and has historically offered citizen-investment participation in German wind farms.
• juwi Group: juwi is a major German renewable energy project developer co-founded by Matthias Willenbacher, the founder of Wi IPP. It develops wind and solar projects under the EEG and shares deep corporate, technical, and cultural overlap with Wi IPP.
• wpd AG: wpd is a German-headquartered wind and solar developer and IPP with German and European operations. It has historically provided structured citizen-investment participation in wind projects, similar to Wi IPP's B\u00fcrgerbeteiligung model.
