Energy traders look to 3TIER when they need the most reliable and accurate renewable power production forecasts.

3TIER is one of the world's largest and most successful independent forecasters of wind power production. We forecast more than 20,000 MW of installed wind generation capacity worldwide, including over 10,000 MW of project-specific production. 3TIER forecasts for the majority of the merchant, non-PPA wind projects in the US, which are most dependent on accurate forecasts. Our forecasting skill has enabled us to achieve a 98% client retention rate.

3TIER's state-of-the-art forecasting products employ the most advanced mesoscale numerical weather prediction (NWP) modeling, proprietary statistical methods, self-learning neural networking technology, and a fully secure and redundant delivery infrastructure to provide the most reliable and accurate forecasts available. 3TIER provides aggregated day- and week-ahead regional forecasts based on established energy trading regions, customized to your geographical sub-region specifications. We also provide hour- to month-ahead wind power forecasts for individual projects.

In addition to wind forecasting, 3TIER also has a long history of hydro forecasting for individual watersheds and on a regional basis. We are the largest independent forecaster for the vast Columbia River Basin in the American Pacific Northwest, and we are able to forecast streamflow anywhere in the world.
