Sustainability Assessment of an Onshore Wind Portfolio in Germany
An Application of the Sustainable Asset Valuation (SAVi) for B Capital Partners.
The sustainability assessment consists of the following steps:
- Valuing, in financial terms, the environmental, social, and economic costs and benefits (externalities) caused by the two energy generation assets.
- Assessing the potential costs induced by climate change risks and how the implied costs affect the financial performance of the energy generation assets if those risks materialize. Air temperature increase (physical climate risk) and the introduction of a carbon tax (transitional climate risk) were assessed as climate risks.
- Integrating the valued externalities and climate risk-related costs into the three components of the assessment:
- Cost-benefit analysis.
- Calculation of the levelized cost of electricity.
- Financial analysis, calculating performance results for the equity and project internal rate of return of both assets.
The results across the three assessment components demonstrate that the wind portfolio is the more climate resilient and more profitable investment choice as well as the more beneficial (less costly) energy generation asset from a societal point of view.
