BOM vs economics reconciliation (P2-12):The BOM FOB total ($14,577,056) prices only the catalogue items (PV + storage); wind turbines and the step-up transformer are POA. The illustrative installed CAPEX ($54,500,000) adds wind at $1,150/kW and covers full turnkey installed cost — the two figures use different bases and are not directly comparable.
P50 / P90:P50 = expected annual generation; P90 = 0.85 × P50 (conservative one-year exceedance, illustrative resource variability). A bankable P90 uses site-measured interannual variability, not a fixed 0.85 factor.
Wind BOP:The wind farm balance-of-plant — collector cables, site access roads, crane pads, foundations and heavy-lift erection — is quoted per project and is included in the illustrative installed CAPEX (not the FOB BOM).
POA equipment:Wind turbine generators and the step-up power transformer (outside the distribution catalogue) are quoted per project (POA) — the BOM prices only the PV and storage from the catalogue.
Grid mode:Grid-connected: the hybrid plant sells energy and uses storage for shifting/firming.

Grid mode:Off-grid mode: storage (and typically a diesel genset) must balance generation against load around the clock — contact us for a microgrid sizing.
How do I size a wind + solar + storage hybrid plant?
Size PV and wind to match the load or export profile, then add storage to firm the output. The calculator's default is 20 MW wind + 30 MW PV + 20 MWh/4 h storage. Capacity is matched against hourly resource and load; storage covers the gap between variable generation and demand. The configurator reports capacity, energy and LCOE.
What is complementarity between wind and solar?
Wind often peaks at night and in winter while solar peaks by day and in summer, so combining them smooths total output and reduces the storage needed to firm it. Good wind-solar complementarity can raise the capacity factor 10-20% over either alone. The configurator analyzes the combined P50/P90 energy profile.
What is the typical capacity factor of a hybrid plant?
Solar-alone capacity factors run 15-20%, onshore wind 25-35%, and a well-matched hybrid 25-40%. The higher and smoother the capacity factor, the better the LCOE and grid value. The configurator computes the combined capacity factor from the wind speed and irradiation inputs.
How does storage firm a renewable hybrid plant?
Storage charges during high-generation, low-price hours and discharges when wind and solar fall short, converting a variable output into a firmer, dispatchable profile. A 4-hour battery covers most daily gaps; 20 MWh/4 h is the calculator default. This raises the share of energy deliverable during peak-price windows.
What grid codes apply to wind-solar-storage hybrids?
Wind turbines follow IEC 61400 and GB/T 19960; PV follows GB/T 19964; storage follows GB/T 36547 and IEC 62933; and hybrid plants follow GB/T 19963 for grid connection. The configurator cites these standards and applies their voltage/frequency ride-through requirements to the design.
What LCOE can a wind-solar-storage hybrid achieve?
Utility hybrids in good resource areas achieve $0.03-0.06/kWh, with storage adding $0.01-0.03/kWh depending on the storage-to-generation ratio. The 20 MW wind + 30 MW PV + 20 MWh default typically lands near $0.04-0.05/kWh. The configurator computes full-cost LCOE with WACC, O&M and degradation.
