Interesting info. Texas has a large number of the mining ops in the US. Have heard some mining operators talk about what you describe here. Trying to convince power producers of their value. Texas is unique as well in the design of its grid. I'm no expert but it has problems but also has some strengths. Demand response seems to be working well there and smart energy producers elsewhere would be wise to study it.
One of the problems in most states is how highly regulated the power producers are themselves. We do not have a free market for power generation. Even Texas which has many different competing producers has a grid operate ERCOT with a monopoly on its position. States like California have companies so regulated by the state that they are private companies in pretty much name only.
