AWS Truepower Releases Windographer 4

by | May 19, 2015

ALBANY, N.Y., May 19, 2015 ” AWS Truepower, LLC, an international leader in renewable energy consulting and information services, announced a major upgrade to Windographer, its market-leading software for analyzing, visualizing, and validating wind resource data from meteorological towers and remote sensing systems. Version 4 allows users to perform numerous tasks more effectively and in less time, while retaining the intuitive, easy-to-use interface that has made the software so popular.

“This version addresses many customer requests,” explains Tom Lambert, Director of Windographer at AWS Truepower. “It adds some really powerful features like a new MCP performance test mechanism, which lets you choose the best MCP method for your site; new calculated column options such as rotor-equivalent wind speed; more advanced vertical extrapolation; and the ability to create a typical meteorological year. It also includes some significant time savers like a calibration module and the Combine Anemometers window, as well as a lot of smaller enhancements to improve ease of use and workflow. We think every one of our customers will benefit from this new version.”

In one example of how Windographer 4 saves users time, it offers the option to download free long-term MERRA data from AWS Truepower’s Windnavigator site in only a few minutes, compared to the four or more hours required to download directly from NASA using the previous version.

The software will be available both as a permanent license and “ for the first time “ as an annual subscription. “The subscription offers low initial cost, predictable budgeting, and immediate access to future upgrades,” explains Lambert. “Plus, you pay only as long as you need it.”

The Windographer team will unveil version 4 at AWEA WINDPOWER 15 in Orlando this week and will provide demonstrations of the new tools at the AWS Truepower booth.

Windographer, along with Windnavigator and Openwind, make up AWS Truepower’s Wind Developer Suite, a comprehensive set of software tools, data products and consulting services for supporting every phase of wind plant development from initial site prospecting to final design and energy estimation.
