It may constitute a partial mitigation but of course it is not a complete answer.

The US grids (I think there are four of them, some of which include parts of Canada) rely on
real-time modelling for information on load-balancing. That real-time modelling is necessarily based
on digital computation, indeed on some specific digital machine(s) in specific places. Mismanagement
of such a machine in real-time was a cause of the 2003 NA East-Coast blackout (see "Resilience is an
Emergent System Property", Ladkin and Sieker, https://scsc.uk/scsc-131 ). That was all before
wide-spread penetration attempts. Grid management is causally dependent on such systems; they are
irreducibly digital and need adequate protection from incursion. The bill doesn't address that.
