Openwind v5027 New Features
Apr 20, 2026
Major advances in offshore wind modeling, enhanced platform integration, and reworked loss functions.
Highlights of the new Openwind update include:
New Offshore Functionality
• Definition of seabed soil profiles
• Fixed foundation costs can be driven by water depth as well as seabed soil profile
• Floating turbine anchor placement and costs can be driven by water depth, buildable area and seabed soil profile type.
• Users can define an anchor footprint which is then respected by other turbine anchors.
• Improved capacitated substation behavior now able to handle three or more capacitated substations

Advanced Loss Modeling
• Overhauled time-series loss functions
• Define a fixed underperformance loss per turbine type
• Use a matrix of power scale factors by wind speed to model a variable underperformance loss
• Track partial availability as derating loss
• Model other fixed performance losses as power curve shifts
Blade soiling loss (user-defined or raster-based)
Blade degradation loss (user-defined or raster-based)
Additional power curve loss
Sub-optimal performance loss
Performance losses can be explicitly user-defined whilst still allowing plant power production to hit 100% minus electrical losses.
