How Xcel Saved $22 Million With Weather and Wind Forecasting

But to be fair, IBM's HyRef isn't the first effort at putting together weather forecasting and wind data analysis. One of these efforts, a partnership in the U.S. between the National Center for Atmospheric Research (NCAR) and Xcel Energy, has been fully operational since 2009 and has saved Xcel tens of millions of dollars. Sue Ellen Haupt, director of weather systems and assessment programs in NCAR's Research Applications Laboratory in Boulder, Colorado, offered more insights into this work. NCAR's roots in this technology, dubbed "Variational Doppler Radar Assimilation System" (VDRAS), go back into the 1990s, extending what has been used for "nowcasting" weather at U.S. Army test ranges to the past two summer Olympic Games. (More details were published in an IEEE journal last fall .) Xcel's service territory (as of early August) covers 107 wind farms totaling 3,746 turbi...
