But do the electric power plant's mining costs pay off?
to consistently meet grid capacity, power plants run above actual demand, and they have to do
something with that excess power. a lot of plants would lease it to bitcoin miners at a discount (load balancing); this plant is choosing to mine themselves instead and pocket the margin. i assume their production costs are significantly below bitcoin market value. i'm sure it's a net positive for their business, otherwise they wouldn't be doing it. in particular, this is a cogeneration plant, so they are much more efficient (lower production costs) than conventional power plants.
