What you'll learn

  • Explore WinJi's TruePower Asset Management Platform


How does one cope with some 340,000 wind turbines worldwide, each delivering 100+ measurements per second? How do you guarantee profitable operations of an industry worth $110 billion globally, making it one of the fastest growing industrial segments in the world?

Switzerland-based startup WinJi capitalizes on two current megatrends: big data and renewable energy. Stamatis Stefanakos offers an overview of WinJi’s TruePower Asset Management Platform, covering the overall architecture and the motivation behind it (lambda architecture, its data vault, and in-stream analysis), the physics behind the data (wind measurement corrections, in-stream calibration of turbine efficiency using neural networks), and the business case (analytics of lost production opportunities, predictive maintenance, expected power prediction, and “day ahead” production forecasting).
