This post got me thinking:
I have about 11 miles commute and an EV that has 25 miles of range if driven 
carefully
(full freeway speeds eat into the range like crazy but maintain a 
range-extending
barely-55 MPH in the right lane and then it is not so bad)
So, if I miss a charge at work (or at home) then I will barely be able to make 
the next 
one-way trip and forget the one after that.

However, in case of a longer power outage, I am much more concerned about the 
state
that my fridge is in than my range. Keeping the meat, milk and other food in the
fridge from spoiling will probably be more important for me than being able to 
use
my EV to commute.

Besides, I have probably half a dozen other ways to get to work if needed, I 
mostly
go by my EV, but once a week I take out the bike and make the trek; I could also
borrow my wife's car or ask her to drop me off if needed, but there is also
public transport: with a combination of different rail carriers I can get close
to work; I know that the bus stops only a block away, but I will need to 
transfer and
then there is always the option of a taxi or similar service (Uber, Lyft) or in 
a
pinch several of my friends would be willing to borrow me a car for a day or I 
can
even ask a colleage to coordinate rides and pick each other up.
No, I am not so worried about getting to work - if I find it too much hassle 
then
I can always work from home or take a day off.
My bigger concern is to provide power to critical loads in the home and for that
an EV is uniquely qualified. Just add an inverter and you are in business.
In a recent unexpected power outage I already tested that my EV has no problem
to keep my fridge running and I am planning on solar to keep my EV charged, so
that I should be pretty self-sustained in a pinch.

I vividly remember a good friend from the nearby city of San Jose telling me
during a heat wave a few years back that the pole pig behind their house burned 
out
due to the incessant heat and theirs was not the only one, so PG&E had run out 
of
spares. It took 3 full days before it was replaced and they had power again,
during this time they had to stay with family since nothing in the home worked 
and
all their food had spoiled, they were not very happy...

Subject: [EVDL] OT: Power outages> Heat-related old-equipment failures, not 
capacity



* Keep disscussions EV related *

As some know, the change in the Earth's climate is currently causing a heat 
wave across N.America.

Depending on the status of your local utility (capacity, equipment, users,
etc.) this could be a problem when trying to get a charge either overnight or 
at public EVSE.

Utility pge.com has a large portion of California's Electricity-supplying 
market.

A report on a SF-CA local TV channel:
http://www.ktvu.com/clip/11595263/concord-pge-prepares-for-more-heat-related-power-outages
 mentions it is not a power-generation capacity issue, like 10 years ago when 
deregulation allowed power plants to purposely manipulate the grid's capacity 
for profit:
http://www.larouchepub.com/other/2006/3331elec_blackouts.html
Power Outages Hit U.S. Grid; Utility Deregulation to Blame August 4, 2006

One-minute into the (ktvu) video shows a chart that details that it isn't the 
power generating capacity (there is plenty of that), the problem is the old 
utility equipment is failing with these higher than normal temperature 
conditions (they did not plan for global-climatic changes). See, 
https://www.fac ebook.com/SFGate/posts/10155684792450594
Power went down in the majority of the outages due to temperature-related 
equipment failures


BTW, pge.com has a history of taking as much profit as possible, and spending 
as little a possible on its infrstructure or the maintenace thereof (though 
their TV ads give lip-service that they care).

*So what does this mean to the plugin EV driver needing a charge, and what can 
be done about outages?

Getting pge.com to change is not my primary focus as it would be a monumental 
effort. Besides traffic snarls from lights not working, now the driver will 
have to contend with no power to get a charge.

Drivers can keep informed where power outages are located from the news, and 
their EVSE finder apps up-to-date & handy (i.e. plugshare.com ). 

If a driver needs to use public EVSE during the daytime (when the heat will 
make the most demand on the aged utility equipment), the driver should have 
different public EVSE routes in mind to navigate around the outages.

Also, if you find that you won't be getting an overnight charge because your 
residence is part of an outage, making a trip to a public EVSE should be 
planned (either before you crash for the night, or for early in the morning 
hours before your work commute).

These heat wave outages will have the same affect as any other acts or God 
(earthquakes, etc.). The driver should have a plan-of attack when these occur.
