Homer City Units 1 & 2 AQCS Project

Sitting on approximately 2,400 acres, the Homer City Generating Station produces enough electricity to meet the needs of two million households.

The Kiewit team consisting of partners from Eastern District, Kiewit Power Constructors, Kiewit Power Engineers and Mass. Electric Construction Co. was awarded the contract to engineer, procure, construct and start up the Homer City AQCS Project Units 1 & 2. This project uses an Alstom NID (Novel Integrated Desulphurization) technology that consists of (2) Pulse Jet fabric filters that will each contain (10) compartments and house a total of over 40,000 fabric filter bags to remove particulate emissions. The project will also feature lime and byproduct conveying systems, PAC (Powdered Activated Carbon) system, (4) lime storage silos, (24) lime day bins, (2) byproduct storage silos, (4) 10,500 hp booster fans, (7) air compressor and dryer skids, 217,000 SF of duct, 13.8kV Switchgear, and Aux Transformer.

Units 1 & 2 are identical 620 MW net supercritical units designed and built in 1969 with steam conditions of 3,500 psig/1,000F/1,000F. These units are equipped with electrostatic precipitators for control of particulate matter emissions, as well as retrofit selective catalytic reduction systems for control of NOx emissions. The new AQCS systems will be installed on Units 1 & 2 for the purpose of reducing sulfur (SO2), mercury, and hazardous air pollutant emissions for compliance with state and federal regulations.
