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.
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.
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.
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.
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.
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.
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 Antelope Station Grid Switching Expansion Project will allow an existing generating station to switch between the SPP and ERCOT grid systems. Kiewit Engineering and Design is designing the switch to a grid configuration consisting of a single-breaker, double-bus.
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.
The Kiewit team consisting of partners from Eastern District, Kiewit Power Constructors, Kiewit Power Engineers, and Mass Electric was awarded the contract to engineer, procure, construct, and start up the Homer City AQCS Project Units 1&2.
