Green Unit Two is a dry bottom, wall fired, pulverized coal fired unit equipped with low NOx burners (LNB), 

electrostatic precipitators, flue gas desulfurization (FGD) and coal reburn technology. Construction commenced in 

1976, the unit has a maximum continuous rating of 2660 MMBtu/hr and utilizes #2 fuel oil for startup and flame 

stabilization, bituminous coal and petroleum coke as primary fuel.
