For me this model looks insane, so you can save a few hundreds of bucks per year in electricity costs, but when extreme events happen (and they certainly will), you will wipeout decades of "savings". You either need some insurance or hard price cap. People are bad at estimating risks...

More like scammers, who are taking no risks because they're just taking a percentage off the top, are bad at communicating risks.
