     · Looking further up the stack another turbine bids in 50 MW at 50 per MW. Even higher up the stack you can see efficiency bid into the auction at 130 per MW and a coal plant bid in at 150 per MW. So what compensation do they receive In this example all of the resources including the wind turbine at the bottom receive 150 per MW.
