[LINK] Electric Vehicles

Tom, Link,

I've really got to wonder about the whole thing about V2G or V2H and the
like.

The oft-quoted worry about "What happens when everyone plugs in at the same
time?" doesn't seem to have come to fruition anywhere - Are there any grids
in the world with reported trouble due to simultaneous grid use for
charging vehicles?

The last decade or two of news about energy had kicked off with news about
how power companies were struggling with Summer time peaks due to more
people using air conditioning, and there was frequent discussions of demand
managed systems where power companies could remotely change the duty cycle
of air con compressors to manage load.
What followed was a massive roll-out of solar with various nice feed-in
tariffs across states, including the one in NSW where the NSW gov't tried
to cut access to the FiT earlier than promised.

Energy generators then complained bitterly about how the peak on a hot day
which used to generate crazy profits had now turned into a double peak with
much less profit because so many people now had rooftop solar, and due to
this loss of the main summer peak, and subsequent loss of the main summer
profits, energy costs would have to spiral to keep the generators in
business.

Off peak hot water systems used to pick up much of the night time load,
helping generators smooth the 24 hour demand and assisting in efficient
running of generation. What we have now is government policy which is
resulting in electric hot water systems being ripped out and replaced first
with gas systems, and now gas is bad(tm) so were now replacing these with
refrigerative systems - it's free, plumbers will even ring you up to tell
you how it's free to replace your hot water system!

Any talk of using a car's battery to feed back into the house/grid is a
short-term kludge which will go away as batteries become cheaper. It's very
much like drawing petrol out of your car to fill your mower because a jerry
can is too expensive - when jerry cans are cheap, no-one syphons from their
car.
Further, using a traction battery is an own goal: batteries are limited in
their cycle life, and are expensive to replace - why prematurely wear out
your car when you can get a built-for-purpose battery in the house?

In the medium term we'll start seeing energy companies offering special
tariffs to EV owners - we saw ACTEWAGL do this about ten years ago, and
powershop does it now: https://www.powershop.com.au/electric-vehicle-tariff/
This uses the simplest and most effective social engineering available:
Price indicators! People obey their hip pockets!

In the long term, household batteries and grid-owned batteries will work
with solar and wind and [insert green generation here] to manage the supply
of power. Cars feeding power to houses and the grid will have nothing to do
with it.
