This Excel-based financial model is a powerful, early-stage tool designed to help investors, developers, and advisors assess the potential profitability of renewable energy projects. Developed by Wambua Mutua, a global corporate advisor with deep expertise in mergers & acquisitions, project financing, and transaction advisory services, the model provides a structured framework for evaluating the financial viability of solar, wind, hydro, and other renewable energy investments.
The model is built to be user-friendly and flexible, allowing users to input key project assumptions such as capacity, tariffs, inflation, operating costs, financing structure, and tax rates. It calculates critical outputs including project IRR, equity IRR, payback period, and net present value (NPV), while also incorporating advanced features like grid constraints, degradation rates, refinancing options, and debt service reserve accounts.
This model is particularly useful during the early stages of project development, when stakeholders need to quickly test scenarios and understand the financial dynamics before committing to detailed feasibility studies or engaging financiers. It supports both P50 and P90 energy yield scenarios and includes built-in checks to flag potential errors or inconsistencies in inputs.
While the model has been independently reviewed by Wambua Mutua, it has not undergone a formal model audit. Users are advised to validate all inputs and outputs before relying on the results for investment decisions, publications, or lender submissions. Wambua Mutua holds no liability for any subsequent amendments or losses arising from the use of this model.
Whether you're an energy developer, investor, or advisor, this indicative model offers a robust starting point for financial analysis and decision-making in the renewable energy space.
