At last, someone with clue. But note the minor details missing in the url: 
price, and lead time.


Plus, the 'last century' guy needs to do a little math. Sure
we can store 50-500 joules. BFD. But the gap between that and that
768KV going flat out is many orders of magnitude more than between
oh 110BPS and OC-48.

The basic issue with all the power nets is really simple to
grasp, in NANOG terms:

	Redundancy co$t$ -- who wants to pay??????


The power industry had no telecom bubble to overbuild
facilities. It's easy to go from OC-48 to OC-96, right? It's far
far harder to double the capacity of a 500 mile or even a 100
mile line. 
	FIRST, there's the money. 
	Then there's the politics.
	Only THEN do you hit the lead-time issue.
	And then....

And to put it another way...

You have a buncha OC circuits, and get hit by backhoe fade. After
you patch the fiber, you first have to junk the ci$co boxes at
both ends because they blew up when the fiber broke. To restart,
you then must get a sync signal from Hillsburo, get everything
all on key & in tune, and then you start the smallest box, the
next one, then finally....  Do it wrong and you get another Star
Trek Bridge panel scene.
