openWind®:
Software developed by AWS Truepower, LLC
A tool for the design, optimization, and assessment of wind power projects
Open-source platform
Patterned after Geographical Information Systems (GIS)
Identical computations to those of other leading wind farm design programs
openWind® GIS functionality:
Create and display vectors and rasters
Clip vector layers
Edit attributes
Edit vectors
Label features
Export vectors/rasters to Google Earth
Add/Subtract rasters
Perform Vegetated and Non-Vegetated viewshed analysis (ZVI)

Approaches to wind farm layout design
Date 9 May, 2011 ESRI PUG Presentation - openWind ® COE Optimizer 4
Standard industry practice is to optimize turbines for maximum production
openWind® Enterprise has the capability to optimize layouts using the Cost of Energy Optimizer (COE)
Takes into account some project cost metrics
COE Testing: Hope to find a way to more automate the process of optimizing wind farm layouts for project valueTested whether or not the COE process had measurable impact on the resulting turbine layout

Wind Farm Layout Design Basics: Create a wind map
Date 9 May, 2011 ESRI PUG Presentation - openWind ® COE Optimizer 5
Inputs to openWind®
Digital Elevation Model (DEM)
Roughness (RGH) – Values assigned to land cover for the site
Meteorology data (TAB file) – Historical, representative met data for the site in the form of wind speed and direction
(wind frequency)
Output (.WRG)
A grid containing probability (P) and wind speed (U) at each pixel in the grid
Defines wind conditions for the site.

Wind Farm Layout Design Basics: Capture site constraints
Date 9 May, 2011 ESRI PUG Presentation - openWind ® COE Optimizer 6
Constraints:
Each site will have specific considerations to avoid, i.e. roads, rivers, steep slopes, etc.
Constraints are defined and mapped in order to create a buildable area in raster form
In Shell Wind, constraints are handled within ArcGIS
