Yep. But it's not. The difference is that utilities are especially regulated because they have monopolistic operations. Part of the quid pro quo for going forward with the monopoly is that they have to be open to buying power back from other producers. I don't have the Oklahoma legislation here, but given the available facts, I'm going to bet that's the case. In other words, this taxation isn't a matter of treating residential power generation like any other business, it's about the utility using the legislators to claw back a commitment they now regret making.
