economy of scale was evident (i.e., using a regression equation, costs ranged from about $200/kW for a 200 MW unit to $160/kW for an 800 MW unit). For 2008 to 2011, the average SCR costs exhibited great variability and again a modest economy of scale was evident (i.e., about $300/kW for a 200 MW unit to $250/kW for an 800 MW unit; 2011$).
