Mains power voltage drop to reduce usage?

Wind turbines don't provide district heating.

They provide anything you can run off electricity. WTF is "district heating"?

So does being clouted over the head with an axe, but you tend to avoid it.

Amazing people still heat their houses using water.

There are well documented cases of inadvertent exposure to extremely high concentrations of CO that caused serious illness and/or death. Two examples are (1) a malfunctioning Zamboni at an ice rink and (2) an improperly recently serviced or installed gas appliance (dryer, water heater, kitchen stove or oven, or furnace) in the absence of a functional CO detector. Before you go to a hockey game or a figure skating exhibition or competition how do you determine that the facility has properly maintained their Zamboni and has very recently tested their CO detector? If you are a dinner guest in someone's home, do you always inquire upon arrival whether or not they had a gas appliance installed or serviced that same day and have a recently tested CO detector? If not, what's your strategy for avoiding those potentially life-threatening environments?

He never does anything lilke that.

He never is, no one is actually silly enough to ever invite him.

He gets real radical and takes his chances.

If found one goes to prison.

Put a paper card in the mailbox for me to read the meter and mail to them.

If I don't, they charge me all the same, with an estimation that is higher than reality.

It is the same power as it was before, with the mechanical meter, or less.

LOL.

The others would also mandate smart meters.

Pure physics. Not amazing at all. Most people in Spain use it.

If you have an unused swimming pool in the basement of your apartment building, just throw in a small research reactor (100 kW to 1 MW) and you have heating for the winter :-)

And getting out of the valley could take half an hour, if you had a bottle of air to breath meanwhile.

Big generators are synchronous generators and the question is how do you connect a large number in parallel (in the national grid) and how properly share the generated power between them. The power delivered depends on the _phase_difference_ between generators i.e. a constant phase difference.

If there would be even a small _frequency_ difference between generators that would cause a constantly variable phase difference. If the phase difference would grow above 90 degrees, a catastrophic situation would occur.

Note that this method of synchronizing generators several hundred kilometers away from each other has been used for well over a century without any other synchronization connection, just the power grid.

Messing up with the frequency would also mess up the phase protection systems.

Wrong.

Well said, downunder. As a result, there cannot be a _frequency_ difference _anywhere_ in the net. The entire net must change frequency.

I'm curious.

Do they have to add chemicals to the water, to keep it clear, no algae or bacteria? Or simply the radiation keeps it "clean"?

School trips to the swimming pool reactors were discontinued many years ago - I'm pretty sure that Bart and Homer had something to do with it .. John T.

Most parts of continental Europe are connected to a single 50 Hz synchronous network (UCTE). UK is connected to this network with under sea DC cables. Scandinavia is also connected to this UCTE network with DC cables. All these three networks are nominally 50 Hz but there are phase differences varying all the time.

Due to the AC/DC/AC connection across the Channel UK could do some strange thing with their network without affecting the continental Europe.or Scandinavia.

They strive to keep the generators perfectly in phase with the rest of the network. Allowing a phase difference would cause reactive power, which is wasteful. The power delivered is adjusted by regulating the field excitation. The input for the regulator is the mains frequency. There are set limits to that process, of course, to protect the installations.

The overall coupling constant for the European network is about 20GW/Hz, IIRC.
