Last Saturday was very hot and at about 6.30 pm a series of short blackouts
occurred at my home in Wollondilly shire on the outskirts of Sydney. I
happened to have a power meter connected at the time and watched as the
voltage dropped from around 230 slowly to 208 at which level the power went
off for a couple of seconds then restarted. The voltage went back to 230 or
so then the process repeated . This went on for about half an hour. I
switched off what I could but it is a pain having to reset all the clocks,
redate the phone etc. The fridges weren't, to happy about it either. Non
peak times the voltage goes up around 250
Maybe we are going to have to have a UPS set up in our homes with all the
changes in the electricity arrangements!

Selective blackouts are the normal response to overloading like that.

Everyone cranks up their aircons at the same time, grid can't keep up,
so it bombs a segment.
It comes back online after awhile, assuming the dickhead users would
have turned off a few things, and the process starts over again.

When there is more load than you can supply, the only option is to cut
power.

This is a no-excuse cheap-arse way to make an appliance. Any way to

There are control boxes that sense brown or blackouts, and forcibly
keep the fridge off for some time before trying again. If you power up
an the wrong moment in the gas transition phase, it can damage the fridge.

Depends where you are. I'm in the thick of Sydney, so the likelyhood
of power issues is less, but it's a growing problem.

Adelaide has this issue, and mainly because aircons have put a very
short high load on the grid. To fix it, you need additional power
generation plants to keep up to the demand.
They have more social problem with power. Population has been really
slow to grow, or stable, so new base power stations are out of the question.

Problem with catering for peak demand is, fourfold:

Peak power generation is expensive, because power needs to be ramped
up and down rapidly, coal (cheap) can't be used.
Peak power, because of its very intermittent usage, as well as being
able to ramp power up and down rapidly, to have to be able to turn it
off too. This leaves only a few options as far as generation goes.
Of all those options left, all are frightfully expensive, AND are not
well suited to huge amounts of power - we're not talking a few
households here, it's an entire city, so solar and wind is out.

So you could either resolve all those issues, or, you can tell your
idiot users to not use their aircons all at the same bloody time.

Which do you think is easier? Smile

it will switch the power back on.

There would be a HUGE liability issue if that was done. But
refrigeration isn't the problem either. It disappears into the base
load, so it not a peak issue.

This is already done with large systems to save power, but it has
nothing to do with peak intervals, it's only to save money to the
company running the fridges. Again, its use averages out to continuous
over 24 hours (along with everyone else) so there is no peak/off peak usage.

Whats wrong with the supplier providing what they sell ??
Why should consumers have to consider all these measures because the

I agree with you, but we know that under the current regime in
Canberra, and states privatising power, that the problems will just
continue and worsen. The public (who are incredibly gullible) must
bear a lot of the blame for this as for years have happily bought into
environmental and other frauds, and have not been vigilant in this, or
in choosing and holding to account their state and federal
governments, voted over and over for fuckheads, state govt (QLD at
least) we have had the most incompetent and backward government in
living memory as far as infrastructure is concerned and from what I
have read in the news over time NSW hasnt been much better.

These problems with the power will not be fixed in the short term, and
are likely to only get worse and worse - until we start getting a
program to build more power stations to fix the problem, and even if
this were to start tomorrow, it would take a long time for them to
come on line.

This is typical of countries/states that are in serious decline or
collapse, the first thing that goes is reliable electricity according
to a guy I worked with who had lived and worked over the years in a
lot of these places when they ran into trouble. This of course wrecks
the economy further, as manufacturing and business cannot function
properly without reliable power, not to mention transport, where
electric trains stop, you cannot refuel cars, and traffic lights dont
work.


As to the other posters:


John Tserkezis

Im not dictating anything, im suggesting these things voluntarily as a
way for the average person to get around the problem and to try and
live a normal life without the hassles. As for gas stoves, it doesnt
matter what the authorites do with the power, as long as your gas
cylinder is full, you can cook either on your gas stove or BBQ. Gas
for cooking is a better alternative than running a generator for an
electric stove, and as long as you can get gas refills or exchanges
locally, there will be no problems.


Fot this reason, in Eastern Europe, you can buy combination gas/
electric stoves (their gas is piped in and is also unreliable like the
electricity, though usually both don't go out at the same time) and
since we seem to want to live that way here, maybe this will be a
future product someone could market here when things get worse with
the power Smile

Not telling anyone WHEN or how to cook, it seems the power authority
is already doing this, by not providing unreliable power

Shit happens. Some people need power available at certain times, so hey
have to take precautionary measures.

It is about the only alternative. There are others, but just as expensive.

Maybe. All the current/past increases have nothing to do with it either.
all due to mismanagement by state governments of both persuasions.
