Scope of Work:

Southern Environmental, Inc. provided detailed engineering, material supply, fabrication, construction management, a 1/12 scale physical model study, electrical wiring, foundation, field construction, insulation and cladding, painting and start-up services for the utility's Unit #3 & Unit #4 Electrostatic Precipitator Project Replacement.


The new precipitator is upstream of a new FGD. The unique construction approach allowed for the addition of a future SCR to be located upstream of the ESP and reduced projected outage time by 50%.
