Windfarm Acquisition Model

Ah, diving into the world of wind farm acquisitions and modeling, are we? Let's tackle your questions one by one, based on the most helpful WSO content and insights from the financial modeling templates available:

1. Capex for an Already-Built Park/Farm: If you're acquiring an already-built wind or solar farm, the construction capex quoted as $/kWh would typically not be directly relevant for your acquisition model. Since the plant is already built, your focus should be on maintenance capex rather than construction capex. Maintenance capex can vary, so it's wise to look into historical data of similar projects or industry standards for maintaining such assets.

2. Debt in CFADS: CFADS (Cash Flow Available for Debt Service) is meant to represent the cash available to cover debt service costs. The initial debt drawdown used to acquire the business would not be included in CFADS. You're correct that debt service costs (interest and principal repayments) are included in CFADS, as they represent the cash flow obligations that need to be met.

3. Model Start Date: If the acquisition date is 12/31/24, and the debt is drawndown on that date, starting your model on 1/1/25 makes sense. This way, your model reflects the financial situation starting from the very beginning of the ownership period, including the impact of the debt drawdown.

4. IRR Calculation: Your IRR, whether levered or unlevered, is indeed the XIRR of the acquisition price and the series of positive and negative cash flows over the investment period. The acquisition price can be influenced by several factors, including the target IRR, expected operational performance, and market conditions. The target IRR is a critical input, as it reflects the return expectations of the investors, which in turn influences how much they are willing to pay for the asset.

5. From Farm Size to Production: To estimate production from the farm size quoted in MW, you would indeed multiply the capacity (MW) by the hours in the period being modeled. However, it's crucial to consider the capacity factor, which accounts for the fact that wind farms do not operate at maximum capacity all the time. The capacity factor depends on the location, technology, and other factors. For example, if a 100 MW farm has a capacity factor of 35%, and you're modeling for a year (8760 hours), the annual production would be 100 MW * 0.35 * 8760 hours = 306,600 MWh.

Remember, modeling for renewable energy projects like wind farms involves a good understanding of both financial principles and the specific operational characteristics of these assets. The WSO financial modeling templates can provide a solid foundation, but always tailor your model to the specifics of the project you're evaluating.
