Smart metering controlling freezers and washing machines so that they
are switched off at periods of peak demand sounds like a good idea,
provided of course they can't be hacked and the whole system reduced
to chaos. The first phase of smart meters does little to inspire
confidence in that direction.

If we're all going to be encouraged to have a few kWh of battery
storage in our garages for peak lopping, I hope the govt is going to
spend more on the fire and emergency services, because they'll
certainly be needed.

As for improving battery technology, good luck with that.

The problem is this is all ****ing in the wind.

at the moment there is about 8 hours of low demand betwen 11pm and 7 a.m.

about 13GW lower (20GW-33GW)

And ist summer too.

You cant leave your frezeer of ALL DAY to tach up overnmnight, and in
any case the net household differential based on 20m houseolds is 650
watts. Which is probably more than the average household uses all together.

Storage requiremenst? so you take 650 watts by night and release it by
day? well 5.2Kwh.

And what do you think THAT will cost, and how long will it last being
charged and discharged every day?

About £750. Plus inverter costs, Plus installation,

Call it £1000 for every household. With a life of 5 years.

20 million households makes that £20bn spent every 5 years on batteries
and inverters.

Makes Hinkley point look cheap.
