> n Texas where ERCOT has signed demand response agreements with many bitcoin mining companies to cut power when demand is high

So the "cryptobros" think this is new and exclusive for crypto? No and no. Their hype to damage ratio is starting to match those of tobacco companies.

[yrral]

I am not aware of any other large consumer of power that can cut power with seconds of notice without economic harm.

Eg: google/facebook datacenters, aluminum smelters, factories, etc.

[raverbashing]

Some domestic users can (for things like AC, heaters etc)

For industrial, they can establish peak-times and broadcast the pricing info. So maybe not "seconds" but they can react to demands and pricing. It is possible (and depending on the industry, likely) that some industries do have backup power on site, so they switch to that and stop using grid power.

[inter_netuser]

only failed states turn off residential AC or heating.

Boggles my mind how some think it's acceptable.

[Thorrez]

I don't think raverbashing was talking about the state turning it off, but rather individual people turning their own AC/heating off.

Nest Thermostat offers many features to automatically do this if users want it, both to save money, as well as to help the planet. Full disclosure, I work at Google, but not Nest.

Nope, smart states do that. Heat can be stored. Heat when it's cheap.

[inter_netuser]

Nah, I'll just run my own generator instead.

[gefhfffh]

Well that's not smart

Aluminum smelters do this all the time btw.

Also there is economic harm in shutting down mining I.e loss of mining fees.

> Aluminum smelters are typically slow to curb production as the costs of shutting down and restarting capacity are high.

> "I think it's clear that one of the issues facing aluminum is that it is costly to bring down smelting capacity and even more costly to bring it back up again," Harvey said during a virtual presentation at the Bank of America Securities Global Metals, Mining & Steel Conference. "I think it has tended to be a relatively slow process for producers to come to those decisions."

> Harvey said each potline at a smelter requires about $25 million to restart, which made it challenging for operators to reach curtailment decisions.

In the long term, I expect this to become very common as hydrogen replaces methane in ammonia production and coal in steel production. Hydrolysis can happen when price is low and as long as the hydrogen buffer is big enough it will last through high prices.

[gefhfffh]

E.g. energy storage systems

[yrral]

They have a max capacity. They cannot be steady consumers of electricity for the 95%+ of the time that there is enough electricity to go around.

[gefhfffh]

So does mining.

Just turn off fossil based plants and you reduce needed max capacity.

Didn't know we have too much energy with a low carbon footprint.
