AWS Truepower Acquires Windographer

December 1, 2014

Agreement reinforces AWS Truepower’s strategic focus on providing integrated analysis and development tools to serve the global wind industry.

ALBANY, NY—Dec 1, 2014 — Continuing its strategy of creating and delivering exceptional wind analysis and development tools, AWS Truepower, LLC, an international leader in renewable energy consulting and information services, has purchased the Windographer software from Mistaya Engineering, Inc.

Windographer is the market-leading software for analyzing, visualizing, and validating wind resource data from meteorological towers and remote sensing systems. These data are fundamental to accurately estimating the amount of energy that will be produced by wind projects.

Windographer complements AWS Truepower’s suite of wind analysis and development tools, which include the wind project design and optimization software Openwind® Enterprise, and the web-based Wind Site Assessment and Wind Data Management dashboards.  Tom Lambert, previously CEO of Mistaya and chief architect of Windographer, will lead the Windographer team from AWS Truepower Canada, a new subsidiary based in Calgary, Alberta.

“Windographer’s success in the market reflects the innovation and passion of Tom and his team,” said Bruce Bailey, CEO of AWS Truepower. “They have created an elegant and useful product for the wind industry, and we are happy that they are joining us to continue to expand its development as part of AWS Truepower.”

Michael Brower, President and Chief Technical Officer at AWS Truepower added, “With Windographer joining AWS Truepower, we will be able to provide the full range of wind software, online services, and data to our customers, who will benefit from more powerful tools and greater cross-platform integration and compatibility. At the same time, existing Windographer users will see continuity and growth in the product they already value.”

“The Windographer team is thrilled to be joining AWS Truepower,” said Tom Lambert. “The vision AWST has for their software suite aligns very well with ours, and their expertise will allow us to advance Windographer farther and faster than we could on our own.”

“It makes sense to all of us as a natural progression in building a world-class suite of wind development tools,” he added.

With the closing of AWS Truepower’s acquisition of Windographer software on November 28, 2014, AWS Truepower will provide the wind industry’s most comprehensive portfolio of advanced wind monitoring and modeling software tools.  For more information on Windographer, visit
