UN Sustainable Development Goals

The investment at a glance

This project is a co-funding initiative with the crowdfunding platform WIWIN. This means that the project is offered simultaneously on both bettervest and WIWIN. A total of €1.5 million is to be raised, with €750,000 being financed by the crowd through bettervest.

Project intent

Ober-Flörsheim Portfolio GmbH & Co. KG (Ober-Flörsheim Portfolio GmbH) is the owner of a wind farm with a total of eight turbines in Ober-Flörsheim, Rhineland-Palatinate. To further expand its product portfolio, the company plans to acquire four additional wind turbines, all of which are located in close proximity to the existing Ober-Flörsheim wind farm. This expansion aims to strengthen the existing portfolio and enable better economic conditions for future Power Purchase Agreements (PPAs). With PPAs already secured for 2025 and 2026 and long-term land use contracts until 2035, the goal is to ensure the long-term and profitable operation of the wind turbines. The objective is to generate stable revenues even after the end of EEG subsidies and invest in future-proof projects.

Social & Economic Impact

The expansion of wind energy strengthens economic development through cost efficiency, attractive investment opportunities, and the reduction of dependence on energy imports. At the same time, it promotes social participation by enabling financial benefits for citizens and communities while enhancing regional cohesion.

Climate protection

By continuing the operation of the four acquired turbines, an annual CO2 savings of 4,200 tons is maintained. By the end of the project's term on December 31, 2030, this will amount to over 20,000 tons of CO2.

Bonus

In addition to a fixed annual interest rate of 6.0%, investors will receive an additional bonus payment of 1.5% if the market value of the generated wind power exceeds 9.5 cents/kWh. This bonus payment will be made together with the annual interest payout.

Established, sustainable company

Ober-Flörsheim Portfolio GmbH & Co. KG, headquartered in Germany, is a renewable energy company specializing in the acquisition, construction, operation, management, decommissioning, repowering, and sale of wind turbines and the associated infrastructure. The company currently owns a wind farm in Ober-Flörsheim, Rhineland-Palatinate, with eight operational turbines. The holding company behind Ober-Flörsheim Portfolio GmbH is Wi IPP GmbH & Co. KG (Wi IPP), which acquires and manages wind and solar energy assets. Founded in 2018, Wi IPP has since built an extensive portfolio, comprising 63 wind turbines with a total capacity of 152 MW and 58 solar plants with a combined 20 MW capacity. These facilities currently supply around 110,000 households with clean, renewable electricity, making a significant contribution to the energy transition.

Project description

The operation of wind energy facilities helps combat climate change, improve quality of life, and shape a sustainable energy future. Renewable energies combine economic benefits with ecological responsibility and social advantages, making them an essential part of the global energy transition.

The German government has set a goal to reduce all greenhouse gas emissions by 65% by 2030. By 2045, Germany aims to be climate-neutral. Renewable energy sources play a crucial role in achieving these goals. Unlike fossil fuels such as coal or natural gas, wind energy does not require limited raw materials and produces no CO₂ emissions during electricity generation.

Furthermore, the expansion of wind power reduces the need to destroy landscapes for coal or oil extraction, protecting habitats and promoting biodiversity.

Wind Bond Ober-Flörsheim II: Investing in a Sustainable Future

To further expand the economic and ecological benefits of wind power, Ober-Flörsheim Portfolio GmbH & Co. KG is investing strategically in the long-term operation of existing wind energy facilities.

Existing Wind Farm Ober-Flörsheim

The company operates a wind farm with eight wind turbines in Ober-Flörsheim, Rhineland-Palatinate. After 22 years of operation, the EEG subsidy has expired. However, a power purchase agreement (PPA) for 2025 at 8.28 ct/kWh ensures the continued profitable operation of the wind farm.

Planned Expansions

Additional Wind Turbine in Flomborn: A wind turbine in Flomborn, near the existing wind farm, is set to be acquired. It is connected to the same grid connection point and could create synergies for an improved PPA from 2026 onwards. The land use contract is secured until 2035.

Three Wind Turbines of the Type Enercon E-48: Additionally, three wind turbines of the type Enercon E-48 (each with a nominal capacity of 0.8 MW) will be acquired. These turbines are technically reliable and also legally secured for use until 2035.

Economic benefits of the portfolio expansion  

The expansion to a total of twelve plants not only increases earnings stability, but also improves the negotiating position for future PPAs. In addition, all bank financing for the new turbines has already been repaid in full, which means that higher profits can be realised.  

With the Ober-Flörsheim II wind bond, Ober-Flörsheim Portfolio GmbH & Co. KG is consistently focussing on the long-term use and further development of existing wind turbines. This not only secures economic returns, but also actively contributes to climate neutrality and the energy transition. 

The business model of Ober-Flörsheim Portfolio GmbH actively contributes to two of the United Nations Sustainable Development Goals (SDGs):

Goal 7: Affordable and Clean Energy

Ober-Flörsheim Portfolio GmbH focuses exclusively on the generation of renewable energy from wind power and its continuous expansion. By doing so, the company plays a key role in providing people with reliable, affordable, and green electricity.

Goal 13: Climate Action

Clean energy and climate protection are at the core of the company’s mission. The reduction of global greenhouse gas emissions can be achieved through the expansion of renewable energy sources. By investing in this project, the acquisition and operation of wind turbines are financed, representing a concrete measure to combat climate change and minimize its impacts.

With the acquisition of the four turbines, all twelve wind turbines of the Ober-Flörsheim wind farm are now owned by the issuer. Without this step, a complete shutdown of the wind farm would have been possible.
By ensuring the continued operation of these four turbines, an annual CO2 savings of 4,200 tons is maintained. The entire wind farm, with its twelve turbines, prevents 17,400 tons of CO2 emissions annually. By the end of the project’s term on December 31, 2030, the additional savings from the four secured turbines will exceed 20,000 tons of CO2, while the entire wind farm will prevent more than 100,000 tons of CO2 emissions over this period.
Additionally, having full control over the site enables future modernization (repowering) once the economic operation of the existing turbines is no longer viable.

As this investment is a subordinated bond, there is no asset backing or collateral and investor claims rank below other debts. It is regulated by the financial market and has the following features: 

Liquidity buffer of 300.000€: The project maintains a €300K liquidity reserve to manage short-term risks. 

Power Purchase Agreements (PPAs): The repayments are supported by long-term PPAs that ensure steady cashflow. 

This financing plan includes the total projected cash flows for Ober-Flörsheim Portfolio GmbH, covering the receipt, initial use, and repayment of the loans.

Investment Requirement

The €750,000 bond aims to finance the acquisition of four wind turbines, all located in close proximity to the existing Ober-Flörsheim wind farm.

The bond has a term of six years and offers an annual interest rate of up to 6.0% p.a. for crowd investors. Investors receive an additional bonus payment of 1.5% if the market value of the generated wind power exceeds 9.5 cents/kWh. This bonus payment will be made alongside the annual interest payout.

The funding threshold for this project is €50,000. If the funding goal is not reached but at least the funding threshold is met, the project owner will still partially invest the raised funds in the acquisition of the wind turbines.

Repayment

The bond repayment will be covered by revenue from electricity sales under long-term Power Purchase Agreements (PPAs), ensuring a stable cash flow.

Repayment Schedule

  • Interest Payments: Interest is paid annually on the 15th business day after the end of the calendar year. The first payment will be made in January 2026 for the year 2025.
  • Bonus Payment: If applicable, the bonus payment will be made together with the interest payout.
  • Principal Repayment: The repayment of the invested capital will be made in six equal annual installments, starting on December 31, 2025, and ending on December 31, 2030.
