Speaking on Deep Background, the Press Secretary whispered:
It seems to me that the power guys are still living somewhere in the last century. Is it really impossible to absorb power spikes? We can go from utility to battery or the other way around in milliseconds, so it
How many kVA are *you* switching?
How many kVA are running through those big 765kv lines?
This is what a *circuit breaker* looks like at those sizes:

8000 amps at 765kv.
And that's just to *break* the circuit without vaporizing itself in the process.
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. -- A host is a host from coast to coast.................wb8foz@nrk.com & no one will talk to a host that's close........[v].(301) 56-LINUX Unless the host (that isn't close).........................pob 1433 is busy, hung or dead....................................20915-1433
