Wind Ultimate Model — Build a Bankable Wind Farm Business Case in Minutes

If you develop, advise on or finance utility-scale onshore wind projects, you know the problem: every new deal means rebuilding the same financial model — recalibrating CAPEX, hunting for market prices, reworking the debt schedule, justifying your methodology to a lender or technical advisor. It takes days. Sometimes weeks. And one wrong formula in the revenue engine can invalidate the whole analysis.

This model eliminates that problem.

Select your country and scenario, enter your installed capacity and revenue allocation — and every output updates automatically. Project IRR, Equity IRR, NPV, payback. A full 20-year cash flow with turbine degradation at 0.5%/yr, OPEX escalation and a complete debt schedule. Ready to present, ready to share, ready to defend.

What makes it different from a generic DCF template

The assumptions are already calibrated for your market. 8 countries — Italy, Spain, UK, Germany, USA, France, Australia and Nordic — each with Conservative, Base and Aggressive scenarios built from BNEF H2 2025, WindEurope 2025, Aurora Energy Research, Wood Mackenzie and national regulatory sources. You are not starting from a blank sheet and guessing at capacity factors. Typical P50 ranges by country are provided in the model so you can immediately sense-check your site data against market benchmarks.

The revenue engine reflects how wind projects actually get financed. Four configurable streams — PPA, Merchant, CfD/FiT and Balancing — with country-specific market configurations pre-loaded. CfD and FiT streams are active only where the relevant mechanism exists in reality: the UK has CfD AR6, Germany has EEG, Italy and Spain are merchant-dominant. Benchmark allocations are pre-loaded and fully user-overridable. A 5% revenue haircut is applied to gross revenues to account for availability losses and curtailment.

Two producibility modes are available. If you have a P50 wind resource assessment, feed it in directly in MWh/MW. If you are at screening stage, the CF-based mode gives you a calibrated market estimate immediately.

The optional BESS module lets you evaluate co-located battery storage with a single toggle. BESS CAPEX, OPEX, arbitrage and ancillary revenues load automatically by country and scenario, giving you a fully integrated Wind+BESS financial picture without building a second model.
