The proposed bill, H. 3968, aims to enhance the protection of South Carolina's critical infrastructure against electromagnetic pulses (EMPs) and geomagnetic disturbances. It introduces Article 29 to Chapter 1, Title 1 of the South Carolina Code of Laws, which defines "critical infrastructure" and "electromagnetic pulse." The bill mandates the South Carolina Emergency Management Division (SCEMD) to develop a detailed plan to harden critical infrastructure against these threats and to provide alternative energy sources for extended independence in case of grid failure. This plan must be distributed to all municipalities by January 1, 2026. Additionally, electrical utility distributors are required to offer programs for residential customers seeking EMP protection, allowing for installation and payment plans through monthly utility bills.

Furthermore, the bill establishes a grant program for municipalities and critical infrastructure entities that comply with the SCEMD's plan, incentivizing them to implement necessary protections. The General Assembly is also tasked with providing multiyear funding starting in the 2025-2026 Appropriations Act to support these initiatives. This funding will be distributed in the form of grants through the SCEMD, ensuring that critical infrastructure can obtain and implement EMP protection and alternative power sources effectively. The act will take effect upon the Governor's approval.
