This is a good companion to Gibney's Zero Day Docu: http://www.recode.net/2016/7/7/12045334/alex-gibney-zero-day...
Went to a SmartGrid conference in 2009. What I learned:
. $1T infrastructure is scheduled to be replaced,
. Power Co's operate on a 30 year amortization cycle,
. Utility regulations can not only change from state-to-state, but from county-to-county,
. The grid is hackable (known in 2009)
