Texas has these free electricity nights. Anyone know of a battery system that can fill the batteries at night (from the grid) and use them during the day? And then recharge at night again. Due to location solar isn’t an option but still interested in batteries due to free nights.

Tesla power wall? No batteries I know of will make economical sense though. Batteries are expensive, wear down and/or require maintenance. After x years / cycles your batteries will be dead and will need to be replaced. Storing your "free" energy in a battery will end up costing more than just buying the energy when you need it. Expensive energy storage is a big part of the reason why "green" energy countries like Ge…
But the part about battery degradation is not true. Tesla Powerwall has a 10 year warranty[1] with 70% capacity retention. This means that Tesla has data showing that the battery will have higher capacity than 70% after those years. That's a lot of cycles and a lot of renewable energy that the battery will provide in its lifetime.

So the day peaked at 85 GW of load, and they got down to only 130 MW of spare capacity. Just 0.15% from running out. And they never asked for conservation? Is it normal to go that close to the edge without trying to cut load?
This is a state that should basically be peppered with residential rooftop solar. Of course, there's zero chance of any sort of state governmental policy to help incentivize it in deep red state land. But if recent history has shown anything, I would consider it a primary feature of any home in Texas to be relatively grid independent with its own generating capacity and storage.
They should 'ask'. After background thought for an hour, they should ask. Their load projections and needs should be fed out to the network somehow, and it should be opt in for the customer to help support the projected load shaping IF they desire and can. It should never be forced upon the customers. The incentives and potential for abuse of the billing provider to provide data that negatively shapes the customer's…

Here in San Antonio (CPS is our sole provider) we get emails asking us to reduce our use during peak hours on high demand days like today. Not sure how well it works, but they send out another email letting us know how we did compared to similarly sized houses in my area. If demand goes over the edge, they will start doing rolling black outs.
"A message from CPS Energy" I haven't paid much attention to them. Perhaps they should put a threat level code in the subject line. Green = Go about your day Yellow = Don't use your big appliances or hot water as much Orange = Yellow, plus turn the thermostat to 80 and keep the doors closed Red = Bitcoin mines offline. All buildings shut down ancillary consumption. A/C in common spaces set to 85. Prepare to roll blac…
We're at a point in time where I can't even tell if this is a joke or not.

Not sure why you consider them to be "green" given the facts you brought up. Germany has never been particularly green energy wise. It's a big population and lots of heavy industry with relatively little energy resources like hydro.
The are building solar and wind quickly now. Maybe that's why you got the impression that they are "green".

Just connect the wires manually To turn on the fan and AC, you'd connect R and Y (or R, G, and Y on systems where the thermostat controls the fan).
Don’t do this, a cheap non-programmable thermostat is a better option and inexpensive.
Your HVAC doesn't care where it gets a 24V signal. An open relay won't mind being energized from the "wrong" direction. AFAIK, thermostats won't tattle.

Uncompensated demand curtailment is such a scam. Just pay people to curtail demand.
What's odd in Texas is that they are resisting the notion of connecting to the rest of the US grid. This would allow them to import power cheaply when they need to and export power when they have too much of it. My guess is that they actually curtail a lot of energy at this point because there's simply too much of it most of the time.
A quick glance at the main page of gridstatus.io shows that right now California and Texas are burning a lot of gas while there is negative pricing due to wind delivering over capacity in the states in between. They are literally paying people to consume more power there while they are paying for huge amounts of gas to be burnt in California and Texas. It's night time there of course so, solar is out.
What's preventing states from doing the obvious thing here? The mid west could be exporting power at a profit right now and instead it has negative power. And California could not be burning many tons of gas right now because there's a surplus of power right next to it.
