An ounce of prevention is worth a pound of cure. So prepare for grid failures etc and promote failsafing the grid and infrastructure.

says terrorists in Yemen and I think Iraq destroyed the power grid there before attacking opponents. It says terrorists could hire Mexican cartels to carry out attacks in the U.S. Or they could activate their own people within the U.S. to do similar attacks on our power grid etc. It says one high-altitude EMP attack could destroy the entire power grid.
_An online article says at http://www.utilitydive.com/news/could-terrorists-really-black-out-the-power-grid/241192 : if nine key electric substations were knocked out, the U.S. would be without power for over a year.
_The National Academy of Sciences (NAS) ... noted that high-voltage transformers, like the 17 that were shot up at the PG&E substation, ... are massive, hard to move and usually custom built.
_NAS recommends the U.S. make and store a set of universal transformers that could be used in emergencies.
_"There are probably less than 100 critical high voltage substations on our grid in this country that need to be protected from a physical attack," former FERC Chairman Jon Wellinghoff told the Wall Street Journal.
_"It is neither a monumental task, nor is it an inordinate sum of money that would be required to do so."
_It says on this site http://securethegrid.com/the-basics-of-grid-security :
_America’s electric grid, data centers, telecommunications networks, and other critical infrastructure can be damaged or destroyed in several different ways: a nuclear weapon that generates an EMP (Electro-Magnetic Pulse) effect; a geo-magnetic storm from the sun that also can generate an EMP effect; a smaller, localized EMP that can be created with everyday equipment from Radio Shack; cyber warfare; and direct physical attacks.

says [An EMP attack] isn’t the only threat to the nation’s electricity grid. U.S. critical infrastructure is also vulnerable to cyber and physical attacks. But ... odds are you have far more to fear from nut-obsessed squirrels than nutty extremists when it comes to the reliability of your electricity.
_... if an adversary did want to start World War III ... the grid might not be the best target. ... some manufacturers of industrial control systems and transformers report that their equipment has been tested and proven robust to such an electromagnetic pulse. ... And for that matter, there are other, easier ways to attack the grid. ... there’s the possibility of a remote cyber attack ... but [it's] less likely to result in physical damage to equipment in the grid.
_National outage reporting data suggests that enemy No. 1 is Mother Nature. ... Moreover, given the changing climate, such severe weather events are expected to increase — indeed, 10 of the most destructive hurricanes on record occurred in the last 10 years. ... Geomagnetic events [also] have the potential to be high consequence
_... it would frankly be prohibitively expensive to make the grid robust to every possible threat. Nonetheless, making the electric grid more reliable and more resilient to natural hazards would be an important first step.
