# Providing Wind Forecasts to Utility Companies

## Benefits

This wind energy forecasting system has saved Xcel Energy ratepayers approximately \$10M per year since 2009. The benefits are described in a report of the National Renewable Energy Laboratory (NREL).

## Challenge

Accurate wind forecasts are crucial for power-grid integration and load balancing. Numerical weather prediction (NWP) models have historically only played a secondary role in providing 0–12 h wind-power forecasts.

## Solution

Wind Energy Prediction System, Forecasting For Wind Energy

Using advanced numerical weather prediction and statistical methods, NCAR developed a highly detailed wind energy forecasting system with Xcel Energy, enabling the utility to capture energy from turbines far more effectively and at lower cost.
