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.
PSE&G selected KHMA, a joint venture comprised of Kiewit Power Constructors, Henkels & McCoy, and Aldridge Electric, to construct the Bergen-Linden Corridor Overhead project. Designed to replace the existing double circuit 138kV transmission system from Bergen to Linden with a double circuit 345kV transmission system, the project will eliminate electric system capacity issues in northern New Jersey and provide better power quality in the region. PJM Interconnection determined the new transmission system was necessary to ensure reliable electric service, eliminate anticipated transmission constraints, and respond to PJM/Federal Energy Regulatory Commission (FERC) mandated infrastructure expansion. The KHMA team is responsible for removing the existing transmission lines and lattice structures, clearing, temporary access roads and bridges, erosion and sedimentation controls, foundation installation (drilled piers and vibratory caissons), steel pole erection, hardware and insulator installation, conductor, shield wire stringing, and fiber optic splicing.
The Kiewit team engineered, procured and constructed the 800 MW natural gas-fired facility with four 200 MW Siemens 5000F(4) simple cycle units and selective catalytic reduction (SCR), oxidation catalysts, exhaust gas-tempering air fan systems and three fuel gas compressors.
Kiewit developed a1.6 MW battery energy storage system (BESS) located in Kauai, Hawaii. Project scope included site design and system interconnection. The Kiewit team worked with the battery and PCS OEMs to streamline integration efforts ensuring adequacy of the overall design and that safety requirements of the local codes were met. Factory Acceptance Testing of the battery was performed at the PCS OEMs facility prior to shipment to site.
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.
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.
Located 5 miles southwest of downtown Memphis, the Allen Combined-Cycle Plant is a 1,100 MW natural gas-fired power plant that replaces Tennessee Valley Authority’s (TVA) almost 60-year-old Allen Fossil Plant. Kiewit was the EPC contractor for the new 2x1 combined-cycle facility, which features two GE 7HA.02 combustion turbines and a Toshiba steam turbine.
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.
