As part of its commitment to expand fuel diversity, Tennessee Valley Authority replaced its two oldest coal-fired units at the Paradise Fossil Plant with a natural gas-fired power plant. Kiewit was selected as the EPC contractor for the new 3x1 combined-cycle facility, which now generates 1,100 MW of power.
A Kiewit-led joint venture completed the civil, mechanical and electrical design and construction of this $28.4 million 50-megawatt (MW) powerhouse. Throughout construction, the team emphasized the need to work toward a common goal by holding partnering sessions with project participants.
To decrease the cost of hydroelectric power and increase the demand for service, Kiewit completed this bid-build contract to expand the Healey Falls Generating Station. Located about 15 kilometers north of Campbellford, the generating station includes a new unit in a spare bay inside the existing hydroelectric power plant once complete.
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.
Kiewit was selected by Public Service Electric & Gas (PSEG) for engineering and procurement services on the Northeast Grid Reliability Project. The project included upgrading existing tranmission lines, converting substation configurations and adding underground circuit to increase capacity while reducing transmission system congestion.
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 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.
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.
This 50-megawatt (MW) hydroelectric plant produces a non-consumptive, non-polluting and renewable form of energy for some 7,000 households. Built under an engineer-procure-construct contract, Kiewit completed the project with minimal impacts to the surrounding landscape.
