The panel on the Woolsley video meeting was concerned over what they seemed to think was a real danger of a very prolonged outage - not an immediate shutdown of backup systems.

The panel stated that it costs less than $2 Billion to protect the grid - an insignificant financial incentive to hype the risk.
