Solar Storm GIC Forecasting: Solar Shield Extension - GIC Forecasting System Requirements

A NASA Goddard Space Flight Center Heliophysics Science Division-lead team that includes NOAA Space Weather Prediction Center, Electric Power Research Institute, and Electric Research and Management, Inc. participants has recently partnered with the Department of Homeland Security Science and Technology Directorate to better understand the impact of Geomagnetically Induced Current (GIC) on the electric power industry. As a part of the process to improve resiliency of the system, better understanding of the power industry user requirements is needed. The ultimate goal in our work is to improve forecasting capability that will support operational decisions about proactive GIC mitigation actions. This report is based on communications with representatives of the US electric power transmission industry and documents the findings as part of the team’s requirements development work.
