I worked closely with an energy company for some time and enjoyed talking with the field maintenace personell and soon discovered that fable of sensible electronics on the power is just that.
Most of the power relies on hardware to control, distribute and protect the grid. And I mean old school hardware, not electronics.
The most electronic dependent part of the grid here is essentially on the end of the line, inside consumers homes, to measure and control the energy delivered and consumed.
Wild fires are more of a menace to power lines and energy distribution than thunderstorms or other massive energy discharges.
