Design wind farms that are more efficient than ever before with Openwind – one of the industry’s most advanced pieces of software for creating and optimizing wind farm design.

Openwind is a wind farm design and optimization software used throughout a wind project’s development to create optimal turbine layouts that maximize energy production, minimize energy losses, account for plant development costs and generate overall project efficiencies.

Our software was developed by drawing on more than 30 years of advisory expertise, which has helped ensure that stakeholders involved in wind project development around the world have confidence in our platform. Additionally, Openwind’s compatibility with other computer wind programs enables you to seamlessly share files and easily migrate existing procedures into our software. 

New release! Check out Openwind v1.9

The latest version has several new features and many improvements to existing features including:

⋅ Substation chaining along with other LCOE optimisation enhancements
⋅ Shadow-flicker strategy creation, assessment, ingestion and export
⋅ IEC61400-12 (editions 1 and 2) obstacle and terrain assessment
⋅ Preliminary induction model based on the work of Dr. ARM Forsting
⋅ Directly import Wind Resource Grid (WRG) files and time series data sets from Windnavigator

Maximize Energy Production 

Laptop featuring Openwind Cost of Energy Optimizer

Cost of Energy Optimization

Optimize layouts and turbine positions to minimize the cost of energy, taking into account energy production, operations and maintenance costs and capital costs including turbine and plant development costs. Understand the impact each turbine has on the bottom line. Arrive at the best layout by taking into account:

  • Access road costs
  • Collector system costs
  • Waterways, pipelines, fence lines, wetlands and more
  • Substation and grid connection locations
  • Electrical losses
  • Power purchase agreement length
  • Operations and management costs
  • Wind resource and wake losses

Gridded Turbine Layers

  • Quickly create and modify gridded turbine layouts using the user-friendly GIS interface
  • Design by hand using intuitive graphical tools
  • Allow optimizer to determine downwind and crossing spacing, grid orientation and obliquity

Reduce and Quantify Uncertainty

  • Model environmental and directional curtailments
  • Accounts for measurement uncertainty, MCP uncertainty and modelling uncertainty
  • Assign turbines to met masts, adjust Wind Resource Grids (WRGs) and run energy estimates
  • Let the software suggest additional sites for met masts to extend the monitoring campaign and minimize project uncertainty

Multiple Design Turbine Layout Option

  • Analyze multiple turbine layout options for cost effectiveness including different hub heights and turbine types

Minimize Energy Loss

Deep Array Wake Models (DAWM) and Standard Wake Models

Leading-edge wake models consider the dynamic interactions between turbines and atmospheric boundary layer as well as allowing wakes to vary with turbulence intensity and stability. Openwind offers users five different customizable wake models to choose from including:

  • Modified Park
  • N. O. Jensen (variety of wake combination schemes)
  • Eddy Viscosity
  • Deep Array Wake Models (Park and Eddy Viscosity versions)

Time Series Energy Capture

(12x24s, annual or long-term time series at hourly or 10 minute intervals)

  • Run energy capture calculations that take into account time-varying temperature, air density, and turbulence intensity
  • Model realistic availability using Markov chain models, which can vary with season
  • Model high wind hysteresis, low- and high-temperature shutdown losses
  • Diurnally varying wake losses
  • Icing losses based on met data
  • Parasitic consumption, blade heating and electrical losses
  • Effects of bat curtailment and NRO modes
  • Output results for entire project or individual turbines

Directional Curtailment, Inflow Angle, Turbulence

Model effects of directional curtailment by specifying curtailment strategy in detail or by setting criteria for automatic sector management.

Non-Ideal Performance Losses

Use multi-height met mast data to assess the effects of non-standard shear using the rotor equivalent wind speed and adjust power curves for different ranges of turbulence intensity.
