Program integration streamlines transition from wind resource measurement to analysis.

Aarhus, Denmark; Hinesburg, Vermont, U.S. July 18, 2013

Plant Solutions at Vestas Wind Systems, a developer of services for power plants, announced a new software compatibility with NRG Systems that enables complete wind resource analysis, from data collection to detailed energy projections. By using NRG Systems' WindPortal® and Vestas' WindData Explorer™ programs together, users can seamlessly process wind measurements in order to make strong project siting decisions.

WindPortal is a web-based fleet management tool for NRG Systems' turnkey Grand Symphonie™ resource assessment system. This software makes it simple for users to securely and remotely access a fleet status dashboard, as well as up-to-date wind measurement data for any site or component. With the click of a button, the data can then be imported into Vestas' WindData Explorer™ software for in-depth analysis.

"We're thrilled to expand the list of WindPortal-compatible software," said Michael Fisher, product manager for NRG Systems. "WindData Explorer is a powerful tool that will help our customers make the most accurate assessments."

WindData Explorer is a free suite of tools used to visualize, analyze and filter wind data. The system supports full traceability of all changes made to data and enables efficient sharing of knowledge through a standardized wind data format or PDF report. It offers automatic detection of all parameters in many logger files, including NRG Systems' Grand Symphonie.

"Wind data analysis should not be a black box," explained Lars Chr. Christensen, vice president of Plant Solutions at Vestas Wind Systems. "It should be a well-documented, transparent process. With WindData Explorer's recording and analytical capabilities combined with WindPortal's data accessibility, project siting is more straightforward than ever."

Vestas' WindData Explorer is now freely available to anyone with an interest in wind analysis. Download the software at http://www.winddataexplorer.com.

NRG Systems' WindPortal is included with all Grand Symphonie systems, and it is compatible with leading software. Learn more at http://gs.nrgsystems.com/, or visit http://www.windportal.com to register and test drive the software.
