NRG Energy unit to continue reducing emissions at Big Cajun II Station Louisiana Generating, a wholly owned subsidiary of NRG Energy (NRG), will continue emissions reductions at the Big Cajun II Electrical Generating Station while providing affordable power to cooperative customers in Louisiana. After buying Big Cajun II, Louisiana Generating upgraded the burners and fuel that reduced nitrogen oxide (NOx) and sulfur dioxide (SO2) emissions by a third. These additional changes and upgrades announced today will further that progress. Work will be done during regularly scheduled outages and completed by April 2015. To meet EPA's Mercury Air Toxics Standards requirements, Louisiana Generating will convert one of the three units at the plant from coal to natural gas, eliminating virtually all mercury and particulate matter from the unit's emissions. Louisiana Generating will also install activated carbon injection on another unit and upgrade the electrostatic precipitators. MATS goes into effect in April of 2015.
