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.
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) installed one of the largest community solar projects in Massachusetts. Situated on 200 acres of the historic St. Joseph’s Abbey, the Spencer Community Solar Farm is 100% subscribed with a rating capacity of 14.7 MW (AC). This installation is comprised of more than 61,000 solar photovoltaic panels powering 1,500 local homes.
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 Woodbridge Energy Center (WEC) is a 700-megawatt gas-fired power plant located on the site of an abandoned chemical plant. It will generate enough electricity to power more than 600,000 homes while increasing grid reliability. In an effort to stay eco-friendly, as well as cutting edge, the facility will use the most advanced generation technology today and, when complete, WEC will be one of the nation’s cleanest and most efficient generation stations.
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.
A Kiewit-led partnership completed its last phase of a six year contract with Cartier Wind Energy by erecting the last of a total of 354 GE 1.5MW SLE windmills, scattered throughout 4 different wind farms in the Gaspésie region: Baie-des-Sables, Anse-Ã -Valleau, Carleton and Gros-Morne.
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.
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.
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.
