Cabe, thanks for the reminder of different technology "vocabularies." I've seen both k and M used in more general contexts to mean thousand, but only MM to mean million. But perhaps general usage is also changing: I just saw M to indicate million in a newspaper article.

Rob,

Thanks!

1. from wiki - A town is only said to have achieved grid connection when it is connected to several redundant sources, generally involving long-distance transmission.

2. from wiki - This redundancy is limited. Existing national or regional grids simply provide the interconnection of facilities to utilize whatever redundancy is available. The exact stage of development at which the supply structure becomes a grid is arbitrary. Similarly, the term national grid is something of an anachronism in many parts of the world, as transmission cables now frequently cross national boundaries. The terms distribution grid for local connections and transmission grid for long-distance transmissions are therefore preferred, but national grid is often still used for the overall structure.

3. The gov is continually looking into grid storage, regulation, and fortification for quite some time now.

4. A lot of the regulation tech is being tested here and there. No overhaul of the electrical grid has been implemented. We still burn a lot of coal. We still lose a lot of energy in heat. I hope to see more work done in this area soon.

Ann,

I was thinking in terms of electrical components apparently. Where 48k is 48000, and 48M is 48 million.

 Again, great post.

Great post Cabe--very informative.  OK, it's time to show my lack of understanding once again.  Would you mind indicating the following?

 1.) Can you tell me the level of redundentcy generally used (and needed) for the "grid"?  Are we looking at multiple redundancy or single?

 2.)  Is there a Federal "mandate" for redundancy or is that decision left up to the individual utility providers?

3.) Do you know if the "Fed" is making any effort at all to upgrade what must be a very well-worm system?

4.) Is this technology now being used or is it still in developmental stages?

Again, great post.

I agree, it's late and insulting. But it's $52 better than $0, and all of it is a lot better than nothing. BTW, I think you meant 48MM; 48M is 48,000.

The $52 dollars for all 48M residents of California is a small and insulting consolation. Buy hey, it's something.

Yep, lived here all my life. A federal court ruled yesterday that we're supposed to get rebates from that mess--finally! After more than 10 years. http://www.latimes.com/business/money/la-fi-mo-court-says-rebates-due-california-20130404,0,5301337.story

Ann,

Were you in California when Enron was manipulating the power distribution?

I heartily agree, Cabe. Plus, I live in California, where some of the worst overcharging occurred.

The fact that a single grid issue caused one of the largest outages on the east coast, and let the company Enron take advantage of the west coast is why we need better protection for the grid. Redundancies and communication protection is essential.
