While the stuxnet virus (whose existence has yet to be proven) could work on a poorly defended system like Iran's, it's doubtful that it could work on more than a small scale here in the US.
Why?
Because most of the systems involved w/ the power grid are actually not networked and a number systems are isolated from an outside access.It might be possible for the Chinese to bribe people into installing the virus. But even then there's no guarantees that the person wouldn't get caught, that teh virus would work or that this action wouldn't be discovered before it caused a problem.
I'm a maintenance planner and I have worked on systems similar to ones described (both PLC-based, as well as SCADA) and I know that w/o serious effort on the part of a determined group or nation-state compromising the power transmission system in the US would difficult, bordering on impossible.
It makes for nice stories and it sells quite a few books, but in reality most of what is proposed is still a decade or so away and may never happen given the proper pre-planning steps.
