I know they store power usage trends and can see how that might help the
power generators. I logged in to my account and saw that when I ran the
AC, the power usage went up. What a revelation! LOL! Other than that,
what use are these things?
Raise the cost of electricity when you want to use it. My wife now does her
laundry after midnight so she can dry the clothes at the low rate. Otherwise
our outrageous electric cost would be even higher.
Did you know that during Earth Hour, when everyone is encouraged to turn off
the lights for one hour, the electric companies pay industry to use up the
power. This is because you cannot shut down a nuclear plant for one hour,
nor stop a hydro dam or even shut down a coal powered generator plant.
Instead of saving money it costs us all extra to not use the lights for one
This is not true. Power plants can throttle down the output, directly,
and bring offline necessary units in running standby, or stopped
Look up "droop mode vs isochronous" via search engine.
Depending on what is going on, and how the plant is operated, switching
all units (maybe minus one) into droop will have the power plant
reacting to load conditions. Many power plants have automatic controls
for such circumstances. Others might have operators that will make
the decision. Shutting the plant down is not necessary.
You are talking about Canada, ya know. They lost a good part of their
grid, and punked some of the Northeastern grid, because of a solar
flare. Meanwhile, the rest of the world laughed. :-)
With modern controls it is rather easy to manage such a situation.
Though, if there has not been an upgrade in 30 plus years...
Anyway, even 40 year old technology can handle the situation if
one would assume that turning the spigot down on the hydro plants would
have the effect of throttling the output and saving the water for later
high demands...of course if OH is no longer using hydropower, they'd
have to have other management tools
not to mention that if they can't schedule production based on what they
knew would be a known drop in consumption, they need to offshore their
Yes, even hydro isn't 100%. There's no benefit in trying to generate
the power for your own pumped storage; it loses.
There are pumped storage peaking units which use off-peak generation for
the purpose to be able to provide peak capacity later. Smith Mountain
Dam hydro unit in VA was built for the purpose; I've not looked to see
whether they're still using it that way or not since have been gone 30
yr or so now...

Hydro One encourages customers to power down for conservation this Earth Ho
TORONTO, March 20, 2013 /CNW/ - Last year, Hydro One customers saved enoug

year by turning off lights and unplugging unnecessary appliances on March 2

Innisfil Wish Event 2012
Innisfil, ON (April 3, 2012) – Innisfil met the Earth Hour challenge with
great success. A 13.93% (4983.91 kWh) energy savings was calculated by Inn
isfil Hydro for the 8:30-9:30 pm timeframe on Saturday, March 31, 2012. Thi
s was the largest energy savings Innisfil has reached in six years of parti
cipating in Earth Hour.
If you have sources for what you claim, we'd like to see them.
Following that logic, the power company should have to be
dumping electricity everyday at 3AM or paying people to take it,
when demand is lower than it is at noon.
Sheer nonsense (on both counts). You don't have to shut it off; unless
it was a _very_ small utility with a very large fraction of participants
that made a difference in demand on their grid of more than the combined
runback capacity of all generation on the grid, they've no real problem
Certainly anybody as large as OH and with a high fraction of hydro that
is about the most flexible there is wouldn't have much problem at all.
The secret police want to know what hours of the day you are home so
they can do a sneak and peek to find out if you have any seditious
tendencies. They will go through all your papers, copy the hard drive in
any computers you have, bug your home and surveil your land line and
cellphone. If you are suspected of sedition, a heavily armed SWAT team
will kick in your door then drag you and your family away for
No reason they can't (except some money). The city I used to live in
was converting over to a "smart grid" that was part of their
cable/Internet system. It would have eliminated meter readers
completely (they had been doing it with the truck up and down the
street, as you suggest, for years).
