Working in a limited space with a five-week outage duration, the Kiewit team engineered, procured, constructed and performed startup of the air quality control system to tie it into Brayton Point’s Unit 3 at New England’s largest fossil fuel-fired power station.
Using an innovative approach, the project team chose to reuse existing ESP steel for the J.T. Deely Unit 2 SCR Retrofit Project instead of opting for demolition. This decision reduced the project construction schedule while minimizing disruption to plant operations.
The Kiewit team consisting of partners from Eastern District, Kiewit Power Constructors, Kiewit Power Engineers, and Mass Electric was awarded the contract to engineer, procure, construct, and start up the Homer City AQCS Project Units 1&2.
Indianapolis Power and Light Company (IPL) provides electric service to more than 470,000 users in the area and surrounding communities, with Petersburg and Harding Street Plants, the company’s two biggest plants, accounting for a majority of that generation. In order to meet EPA Mercury and Air Toxics Standards (MATS) compliance, IPL is retrofitting five units at these sites with new environmental control equipment.
KCP&L and Westar Energy selected the team of Kiewit and Sargent & Lundy LLC to engineer, procure and construct the retrofit to the 1500 MW plant. The La Cygne Generating Station Environmental Retrofit Project includes the installation of two Hitachi wet FGD scrubbers and new Hamon fabric filters on Unit 1 and Unit 2; and a selective catalytic reduction (SCR) system, low-NOx burners and over-fire air system on Unit 2 of the facility.
The Kiewit team was awarded the contract to design and install the Ghent Coal Combustion Residuals (CCR) Transport Project. Upon completion, it will condition, dewater and transport CCR from the four coal-fired boilers to a remote landfill storage. The project includes the installation of a pneumatic system for conveying fly ash, including fly ash storage silos, gypsum dewatering facility and bottom ash dewatering facility. The ash handling project incorporates a 1.8-mile overland pipe conveyor for transporting the dewatered CCR to a landfill.
Kiewit was selected by Kansas City Power & Light to provide engineering and design assistance to replace the existing boiler ventilation fans, dampers and associated electrical components of the Sibley Generation Station Boiler Building--a coal-fired facility. Four ventilation fans were added around the boiler envelope on levels 2 and 3 to more effectively cool the boiler and associated equipment. The east wall of the boiler/turbine building will be cut to add additional intake openings and motorized dampners to aid in proper ventilation of the building.
