solar shield


The solar shield project helps protect electric power companies from the extremes of space weather through improved forecasting. Power grids rely on high-voltage transformers that are vulnerable to surging electric currents ultimately caused by incoming solar material blasted off the sun. 

Solar Shield helps map out where and how strongly such currents, called geomagnetically induced currents (GICs), may impact Earth, thus giving power companies enough warning to protect their systems. 

The project relies on large-scale models of the sun-Earth space environment hosted by the Community Coordinated Modeling Center (CCMC) at NASA's Goddard Space Flight Center in Greenbelt, Md. Solar Shield is a DHS Science & Technology (S&T) funded collaborative project between NASA Goddard Space Flight Center, NOAA Space Weather Prediction Center, the Catholic University of America, Electric Power Research Institute (EPRI) and Electric Research & Management.
