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.
Mass. Electric Construction Co (MEC) installed an 880 KW roof mounted PV system on the Waltham High School in Massachusetts. The scope of work included PV modules- 3080 each LG250 mods; inverters 2 each- Solaron 333kW; an Hb Solar Mounting System (100% ballasted) including ballast; Solar BOS fused Combiner Boxes; Data Acquisition System (DAS); and (8) 200A rated Fusible DC Disconnect.
The Kiewit and Henkels & McCoy team (Kh&m) was selected to construct the New Jersey portion of the new Susquehanna to Roseland Electric Reliability Transmission Project.
The project included the design and construction of transmission structure foundations, including upgrading and converting existing 138kV to 230kV with new structures, power conductors and OPGW. The project also incorporated the demolition and reinforcement of existing 138kV structures.
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.
Mass. Electric Construction Co (MEC), partnered with Cypress Creek Renewables (CCR) to construct a 97 ME Solar Farm in Forest City, North Carolina. The 489-acre solar farm is expected to power more than 11,000 homes in Rutherford County. MEC was selected as the preferred contractor for our excellent safety and quality performance, as well as reputation for helping other solar developers across the country meet fast-track installation schedules.
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.
Ontario Power Generation (OPG) awarded Kiewit-Alarie, a Partnership (KAP), the design-build contract for the redevelopment of the Wawaitin, Sandy Falls and Lower Sturgeon hydroelectric Generating Stations (GS) on the Upper Mattagami River and the Hound Chute GS on the Montreal River.
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.
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.
