Our Unique Value Proposition

Why WinDForcer?

Terrain Classifying capability

§ The package has the capability to recognize site terrain and to classify it as flat, moderately complex and

• complex. The model selects an appropriate route to

computation.

1

Integrated Software Architecture

§ Conventional software packages highly cumbersome § Conventional softwares require tab files and multitude of programs to run.Large project may require waiting period of for 12 hours or more for the resource grid to be prepared. § WinDForcer is an integrated program that gives results within 15 minutes of inputting the data.

2

Data Synthesis

§ We all know that wind speed data received from a measurement can be either has erroneous data or missing data. § Under most conditions, WinDForcer is able to fill the missing data, through the analysis of the time series.

3

Comprehensive & Customizable reports

§ The program generates varied kinds outputs in CSV and XL format including a comprehensive report in PDF.

4

User Friendly Interface

§ WinDForcer has a user friendly interface with interesting visualization and graphics. § The software can be customized as per the client, if requested.

What derives accurate wind predictions ?

Accurate wind predictions Reduces Uncertainty and risks Bankable wind report

Wind Resource Assessment

 More accurate wind predictions leads to less uncertainty and risks  A reduction of the error margin up to 7-10 % (compared to 12-15 % for P90), can reduce a project’s cost of funds by 0.5-0.75% (The Economist 2010).  This reduction in cost of funds would lead to an even higher impact on ROE

Monthly Energy Generation (GWhr)

Actual Generation Energy Generation from WinDForcer

Site was planned with 1.65 MW WTG, the annual generation projected by various softwares was 49 GWhr/year corresponding to PLF of 34%

A wind-farm problem resolved !!



After the WPP was implemented, it was found it was giving a PLF of 22-23%.



WinDForcer reassessed the site, the generation is predicted with PLF of 24.12% at P50 which is very close to actual PLF.
