> It turns out that a big problem is that whenever we install local generation it costs utilities a ton of money So a question: - Lets hypothesize that distributed, decentralized systems cost way more than centralized systems - If you agree with that hypothesis, can we next hypothesize that building a distributed, decentralized system that can support power on one block and can allow it to continue to stay on while the "central feeder line" (please tell me the proper word for this made up word is) to all the blocks is down, because that one block has a local distributed, decentralized power source, is of value to the community? In the past, commercial factories were the only places that could afford this kind of redundancy but it feels to me, thanks to crashing prices of solar and batteries (I could never have imagined 12kWh brand new LFP could be purchased for $2k), this level of redundancy is now very much realistic at the consumer, residential level. It just doesn't work locally today because the utility poles lack the smarts to do the isolated switching and safe islanding. For example: one unsettled question today is if a lot of customers on one such island are on solar and the grid is down, how do we safely supply power within nominal specs to the whole of the island - but this isn't a physical unknown, we know how to solve it. It just is lacking implementation. > These costs, which include debt service, maintenance, upgrades etc amount to 5-7 cents/kWh. Whenever you generate your own energy you cost the utility 5-7cents/kWh that they have to pay regardless of your usage Capitalism has repeatedly proven its ability to cut costs down while improving QoS. I realize you really believe in the numbers you have been provided - that it costs a utility 5-7cents/kWh that they have to pay regardless of my usage, but before SpaceX, it used to cost multiple millions of dollars and years of planning and design to launch one rocket. | ||
