Project owners, facilities managers, schedulers, and operations and maintenance staff look to 3TIER when they need the most reliable and accurate renewable energy 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 models, proprietary statistical methods, self-learning neural network technology, and a fully secure and redundant delivery infrastructure to provide the most reliable and accurate forecasts available. 3TIER provides hour to month-ahead wind power forecasts for individual projects, as well as aggregated regional forecasts for energy traders and grid operators.

3TIER also has a long history of hydro forecasting for individual watersheds and larger regions. Combining our skill in numerical weather prediction modeling with an intimate understanding of spatially distributed hydrological models, we offer short-term streamflow forecasts that are used primarily for reservoir flood control operations and management, and long-range forecasts (up to a year ahead) that are used for water management and energy trading. 3TIER is 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.

For projects that fall outside the scope of our core products, you can also get flexible access to 3TIER's renewable energy expertise, data resources, and computational horsepower through our Advanced Applications group.
