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.
As part of Xcel’s compliance with the Colorado Public Utilities Commission’s approved emissions reduction plan under the state’s Clean Air-Clean Jobs Act (CACJ), the utility will retire its coal-fired units at Cherokee Station located in Denver, Colo. Xcel Energy retired Unit 1 (107 MW) in May 2012 and Unit 2 (106 MW) in October 2011; Unit 3 (152 MW) will be retired in 2015, and Unit 4 (352 MW) will be converted to natural gas in 2017. The new Cherokee 569-megawatt 2x1 Combined Cycle Power Plant will provide replacement power at the Cherokee Site.
Kiewit was awarded the contract for engineering and procurement for the Napanee Generating Station in Napanee, Ontario. The 970 MW gas-fueled facility will provide reliable on-demand power to local homes, schools and businesses as well as replace existing coal-fired power in the providence.
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.
Kiewit designed the automated water treatment chemical feed and replaced the existing manual chemical feed system with an automated system, including chemical feed tanks, pumps and instrumentation.
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.
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.
Kiewit provided owner's engineering services to Duke Energy for their Hines Energy Complex. The scope included a technology and feasibility study and subsequent delivery of owner specifications for EPC delivery of a combustion turbine inlet chilling system.
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.
