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.
- rrrazdan 5y agoAluminum smelters do this all the time btw. Also there is economic harm in shutting down mining I.e loss of mining fees.
- yrral 5y ago> Aluminum smelters are typically slow to curb production as the costs of shutting down and restarting capacity are high. https://www.bloomberg.com/news/articles/2021-12-22/europe-s-largest-aluminum-smelter-trims-output-after-power-spike https://www.bloomberg.com/news/articles/2021-12-22/europe-s-... > "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. https://www.spglobal.com/platts/en/market-insights/latest-news/metals/051420-high-costs-challenge-smelter-responses-to-aluminum-oversupply-alcoa https://www.spglobal.com/platts/en/market-insights/latest-ne...
- gefhfffh 5y agoE.g. energy storage systems
- yrral 5y agoThey 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 5y agoSo 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.
- raverbashing 5y agoSome 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 5y agoonly failed states turn off residential AC or heating. Boggles my mind how some think it's acceptable.
- gefhfffh 5y agoNope, smart states do that. Heat can be stored. Heat when it's cheap.
- inter_netuser 5y agoNah, I'll just run my own generator instead.
- gefhfffh 5y agoWell that's not smart
- Thorrez 5y agoI 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.

- yxhuvud 5y agoIn 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.
