I think this already exists. I've read that aluminum smelters (very very energy intensive) get a discount rate that you describe. I think all very large scale industrial projects interact pretty extensively with the power provider to make sure that both parties know how the impact to the grid can be managed. I can't imagine that a 50MW industrial operation just pays their power bill the way you and I do.
