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.
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.
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.
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.
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.
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.
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 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.
