I've been involved in several aspects of Smart Grid security for some time now - ranging from embedding security in to the smart meters themselves through to penetration testing of national power grids and nuclear plants.

Without getting in to the nitty-gritty of particular technologies and their respective security flaws, I think many people underestimate the advances that have been made in overall system security as we progress towards a Smart Grid infrastructure.
