Both forecasts include hourly values for aggregate power in megawatts, generating capacity by percentage, and aggregated capacity-weighted wind speed.
Optional Features
-
Where aggregate power data is available, 3TIER can apply model output statistics (MOS) to the model simulations, reducing overall forecast error and correcting forecast biases. The forecasted and observed power for a specified time horizon is shown as an easy to interpret time-series graphic.

Aligned with 3TIER's commitment to using state-of-the-art, proven, and transparent methods, our regional wind forecast system is a combination of publicly available global and regional weather forecasts, high resolution surface data, and highly customized mesoscale numerical weather prediction (NWP) models. The result is an aggregate wind speed forecast converted into real world values of hourly power generation in megawatts using asset-specific manufacturer power curve data. Where aggregate power data is publicly available, the forecast will incorporate observations to make statistically corrected power forecasts.
Customer Requirements
In order to provide regional wind power forecasting, 3TIER only requires you to select your region of interest and provide sub-region geographic boundary specifications or wind plant lists.
