Texas isolated power grid design means they have no where to ship excess energy to (in relevant amounts, neither can they get missing energy). It's also under-provisioned but increasing supply is a problem because of excess energy. So they started making deals with miners where the miners act as a sponge for excess energy and in turn pay much less. Taking the same situation just more extreme (and likely more local) and being payed for handling excess energy doesn't seem absurd. (I intentionally didn't judge anything about the Texas gird here, it's just meant as an example.)
