Wind Ultimate Model — Build a Bankable Wind Farm Business Case in Minutes
You have a wind farm to evaluate. This production-ready Excel model gives you a fully calibrated 20-year DCF across 8 countries and 3 scenarios
Further information
This model enables developers, advisors and investors to evaluate the financial viability of a utility-scale onshore wind project across 8 international markets without building a model from scratch. It supports scenario comparison across Conservative, Base and Aggressive assumptions with a single selector, assesses the incremental value of adding co-located BESS storage, and produces Project IRR, Equity IRR, NPV and payback from a fully integrated 20-year cash flow with turbine degradation. It supports two producibility approaches — Capacity Factor-based estimation and P50 direct input from a wind resource assessment — and enables analysis of revenue stream composition across PPA, Merchant, CfD/FiT and Balancing streams with country-specific market configurations and full user override capability.
This model is best suited to utility-scale onshore wind greenfield projects in the 10–500 MW range at early-stage feasibility or commercial evaluation, prior to full technical due diligence. It is calibrated for Italy, Spain, UK, Germany, USA, France, Australia and Nordic markets, and works particularly well when a P50 wind resource assessment is available to feed directly into the producibility module. It is also well suited to projects considering co-located BESS as an option to be evaluated incrementally, and to advisory, M&A and financing contexts where a clean, auditable Excel model is required.
This model is designed for onshore wind only and is not suited to offshore wind, which has materially different CAPEX structures, vessel-based O&M logistics and financing terms — for that use case, the Offshore Wind Ultimate Model is the right tool. It does not cover distributed or small-scale wind installations where behind-the-meter logic applies. It is not suited to markets outside the 8 pre-loaded countries without manual customization of the assumption sets. It should not be used as the sole basis for a final investment decision — it is an indicative tool and must be supplemented with site-specific wind resource data from a bankable P50 study, actual grid connection and permitting costs, and professional legal, financial and technical advice. It is also not appropriate for BESS configurations that charge from the grid rather than from the co-located wind plant.
