“Nodal pricing” exists in several markets but isn’t often used. One example is in Ontario the nodal price in Thunder Bay was always very low since industry there had collapsed but there were still three coal fired power plants. They could bid a low price so it would be accepted, and due to low local demand the supply and demand solved for a low price in Thunder Bay, but due to transmission constraints all of the bidders could not generate what they bid, so they would have to be constrained off. I can’t recall if they got a payment for the power they weren’t able to generate.
