Seize Opportunities when Wind Blows

e-AccuWind® is a 24/7 online forecasting service that delivers extremely accurate wind generation forecasts. These forecasts can be generated for different horizons with hourly or sub-hourly resolutions. The forecasting engine consists of an ensemble of several different intelligent system based models that employ various state-of-the-art technologies. These models capture the nonlinear and complex relationship between the generated power and its driving factors such as hub level wind speed & direction, number of operational turbines, curtailments, and more. The wind forecasts are available for the power markets both at the system-wide and individual farm levels and for client-specific farms. You can access forecasts via web posting, FTP, and Excel. Our experienced experts continuously monitor model performance, ensuring the most accurate and reliable data at all times.
