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 consortium of TIC – The Industrial Company (TIC) and Mitsubishi Heavy Industries America, engineered, procured and constructed the Petra Nova Carbon Capture Project, the first in the U.S., at NRG’s WA Parish Generating Station. The post-combustion carbon capture system reduces the facilities emissions by 90 percent and removes 5,000 metric tons of carbon dioxide daily. Captured from a 240 MW slipstream of flue gas, the carbon dioxide is compressed and transported to a mature oil field where it is injected to release more oil.
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.
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.
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.
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.
Located 5 miles southwest of downtown Memphis, the Allen Combined-Cycle Plant is a 1,100 MW natural gas-fired power plant that replaces Tennessee Valley Authority’s (TVA) almost 60-year-old Allen Fossil Plant. Kiewit was the EPC contractor for the new 2x1 combined-cycle facility, which features two GE 7HA.02 combustion turbines and a Toshiba steam turbine.
The Kiewit team engineered, procured and constructed the 800 MW natural gas-fired facility with four 200 MW Siemens 5000F(4) simple cycle units and selective catalytic reduction (SCR), oxidation catalysts, exhaust gas-tempering air fan systems and three fuel gas compressors.
