[chbot] Fwd: 60 min of free power per day

[Mark Atherton]

Oops I missed something important.

We are using Meridan, and the $0.35/$0.15 rates quoted are from their 
Day/Night service rate.

Hello All,

Only just found about this energy company, and their offer of 60 min of
free off-peak electricity per day -
https://www.electrickiwi.co.nz/hour-of-power

Haven't run-the-numbers yet to see if there are real savings to be had,
but figure this might make an interesting chocolate-fish-challenge for
the group.

So the question is: how maximize the benefit of this kind of offer.

So for a 60A service to a house, this is almost 14kW, and at $0.35 per
(daytime) unit, this could amount to just under $5 per day, if the
entire 60A could be consumed. This amounts to around $150 per month
possible savings.

Obvious thing to turn on is the heater on the hot tank (3.5kW), which
would normally be heated at the night rate ($0.15 per unit), so only
$0.52 savings here.

So, the problem looks like it converges on a need for daytime power, if
the higher saving is to be leveraged.

Anyway, just a daft thought experiment.

Comments welcome.

-Mark
