1. SF Golden gate bridge ( SF Downtown, in general )
2. Google homepage
Both turned off their lights in support for “Lights out SF”, an energy conservation event. Check the comments for some linkage. ( In 1, you can see that many other buildings have turned their lights off in support)
I have given points to anyone close to “Energy conservation”. No points for “Grid Outages” :P

Lets see… the lights on the sanfran bridge went out due to some power outage or grid overload, and google decided to help in saving power?
Like the blackle.com?

Google's homepage for SF users on Oct 20th.
Google offered its support by making their homepage look like "Blackle".
PS: I wonder, if they were truly non-essential, why would they have this just for a hr :P
Eiffel tower did it some time back.

Pic 2 is Blackle!! The Google homepage switched “off the lights” and went black for the same one hour for all Google.com visitors
This is a part of googles initiative to turn off lights or switch to power saving lights in San Francisco to save energy. I think the project is called Lights Out San Francisco or something like that

To promote this event, Google's homepage changes its background color from white to black.Google's callin it Blackle.
Second shows the google page on that day when google also turned its lights out in the campus and debuted a new search engine page for the San Francisco users which is based on a dark-colored layout.
The page design itself was not to save energy directly but to spread the word.(Google had been shrouded in the controversy whether its white background page radiates more energy or not).

Google users in the San Francisco Bay Area will notice today that we “turned the lights out” on the Google.com homepage as a gesture to raise awareness of a citywide energy conservation event called Lights Out San Francisco.
On Saturday, October 20, 2007, Lights Out San Francisco invites the entire city of San Francisco to install one compact fluorescent light bulb (CFL) and turn off all lights for one hour, from 8:00 pm to 9:00 pm PDT. According to estimates, turning the lights out in San Francisco for even one hour could save as much as 15 percent of the energy consumed on an average Saturday night.

Google introduced blackle.com with a black background to conserve watts
San Francicso observed "Lights Out San Francicso" and, precisely at 8 p.m., the entire city turned off all nonessential lights for one hour on Oct 20 this year.
on the 20th of Oct

The outage in Chicago because of too much power usage ?
And though I guess the answer is not this, maybe you can still check out http://www.blackle.com/

For saving power? apparently a black background google would help in saving more power than the white background..

Google doodle for the same.
Lights on the bridge were turned off to save energy, more over the bridge can be viewed as a shilioute in the brightly lit surrounding.
And Google's new Backle uses black color as the background to save some power. (White background consumes more power when compared to black color display)
