The "Protecting South Carolina Citizens from the Risks of Solar Storms and Electromagnetic Pulse Act" aims to enhance the state's preparedness against potential disruptions caused by electromagnetic pulses (EMPs) and solar storms. The bill introduces Article 29 to Chapter 1, Title 1 of the South Carolina Code, defining "critical infrastructure" and "electromagnetic pulse." It mandates the South Carolina Emergency Management Division (SCEMD) to develop a comprehensive emergency preparedness plan that includes measures to protect critical infrastructure from EMPs and outlines alternative energy sources to ensure continued operation during prolonged outages. This plan must be distributed to all municipalities by January 1, 2027.

Additionally, the bill establishes a grant program for municipalities and critical infrastructure entities that comply with the SCEMD's plan within one year. The General Assembly is required to allocate multiyear funding starting in the 2026-2027 Appropriations Act to support these entities in implementing EMP protection measures and securing alternative power sources. The act will take effect upon the Governor's approval.
