Outline of South Carolina shaded for moderate disruption risk
South Carolina outline, shaded by our overall risk read: Moderate. Boundary from US Census cartographic files.

South Carolina logged 2 federal disaster-related declarations in 2026. Here is how that, the Duke, Dominion and Santee Cooper (SERC) grid and national fuel and cyber risk shape the next 6 to 18 months.

Overall read: Moderate. Window: Nov 2026 to Apr 2028. Built Nov 6, 2026 from the national and Oregon Disruption Watch assessments plus OpenFEMA and NWS data pulled the same day.

What's moving

  • Fuel: East Coast distillate stocks were 21.8M bbl in the week ending Oct 23, 14.3% below a year earlier; EIA forecast them 20-30% below average through winter. (EIA, Oct 28, 2026)
  • Weather and hazards: OpenFEMA lists 2 federal declarations for this state in 2026 (1 major disaster, 1 emergency, 0 fire management). Most recent: 3632 (emergency, Severe Winter Storm, Jan 23, 2026); 4908 (major disaster, Severe Winter Storm, Apr 7, 2026). (FEMA, pulled Nov 6, 2026)
  • Grid and fuel context: Grid: Duke, Dominion and Santee Cooper (SERC). Fuel market: EIA East Coast (PADD 1). Nationally, US retail diesel was $6.292/gal on Nov 2 and EIA expects distillate stocks about 11% below the five-year average this quarter. (EIA, Nov 2, 2026)
  • Cyber: National cyber risk is rated High: CISA warned Oct 8 of China-linked actors in US critical infrastructure and Oct 21 of SafePay ransomware (about 600 victims in 2026). No state-specific confirmation is implied unless listed above. (CISA, Oct 8, 2026)

What's claimed

No circulating claims specific to South Carolina were checked in this pass. The national claim below applies.

  • Claim: White-powder letters were mailed to election officials nationwide. Status: Confirmed by FBI/USPIS public alert; none found hazardous so far. Offices in at least 32 states received them, but this page did not confirm whether this state was one. (FBI IC3)

What's sourced

Dated sources used on this page. Primary sources were preferred; news reports are labeled by outlet.

What we don't know

  • Evidence is thin for South Carolina: this pass found fewer than two dated, state-specific primary-source items beyond federal declarations and weather alerts. Absence of items here is not evidence of low risk.
  • NERC's 2026-27 Winter Reliability Assessment is due Nov 18, 2026, so regional reserve margins for this winter are not yet published here.
  • No dated evidence was gathered for this state's meat, poultry, dairy, grain mills, cereal, produce packing, cold storage, pet food or feed mills; no disruption is claimed.

What to watch next

  • Nov 18, 2026: NERC Winter Reliability Assessment, especially the section covering Duke, Dominion and Santee Cooper (SERC).
  • Weekly: EIA East Coast (PADD 1) distillate stocks and retail diesel.
  • Weekly: USDA APHIS bird-flu detections in poultry and dairy herds in this state.
  • Canvass and certification of Nov 3 results into Jan 2027.
  • Late Dec 2026 to Feb 2027: expected respiratory hospitalization peak (CDC).
