House Resolution No. by Representative Crews urges Louisiana utilities to evaluate their electric grids for vulnerabilities to ground induced currents (GICs) and the resulting harmonics. GICs, which can be caused by solar weather events and high-altitude nuclear electromagnetic pulses, pose a significant threat to the electric grid by potentially leading to transformer saturation and widespread power outages. The resolution highlights the need for utilities to utilize the latest standards from the International Electrotechnical Commission (IEC) and the Institute of Electrical and Electronics Engineers (IEEE) to assess these vulnerabilities and to explore federal funding opportunities to implement protective measures.

The resolution calls for a comprehensive assessment of the state's electric grid, taking into account the age and condition of transformers, and suggests identifying hardware solutions to block GICs from entering the grid. It emphasizes the importance of mitigating the risks associated with GICs, especially given historical events that have caused significant disruptions to power systems. The resolution also requests that copies be sent to relevant state and federal authorities to ensure awareness and action on this critical infrastructure issue.
