PJM had some geomagnetic disturbance warnings, but did not progress to the alert stage or grid re-configuation actions. So, no US power grid problems.

    104955 Warning Geomagnetic Disturbance Warning 01.19.2026 14:30 
    PJM-RTO
    A Geomagnetic Disturbance Warning has been issued for
    14:30 on 01.19.2026 through 16:00 on 01.19.2026 .
    A GMD warning of K8 or greater is in effect for this period. 
    End time: 01.19.2026 16:00

(All times are prevailing Eastern US time)

I've posted on this before, for other warnings. Not going to repeat that.
