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.
Kiewit was selected by Kansas City Power & Light to provide engineering and design assistance to replace the existing boiler ventilation fans, dampers and associated electrical components of the Sibley Generation Station Boiler Building--a coal-fired facility. Four ventilation fans were added around the boiler envelope on levels 2 and 3 to more effectively cool the boiler and associated equipment. The east wall of the boiler/turbine building will be cut to add additional intake openings and motorized dampners to aid in proper ventilation of the building.
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 provided project development services, including: site plan drawings, heat balances, water balances, one line diagrams, and permitting support for a 200 MW simple cycle facility adjacent to a 1x1 450 MW combined cycle facility on the same site. The project aims to satisfy area demand for peaking power and variable load from renewable energy sources.
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.
As part of Xcel’s compliance with the Colorado Public Utilities Commission’s approved emissions reduction plan under the state’s Clean Air-Clean Jobs Act (CACJ), the utility will retire its coal-fired units at Cherokee Station located in Denver, Colo. Xcel Energy retired Unit 1 (107 MW) in May 2012 and Unit 2 (106 MW) in October 2011; Unit 3 (152 MW) will be retired in 2015, and Unit 4 (352 MW) will be converted to natural gas in 2017. The new Cherokee 569-megawatt 2x1 Combined Cycle Power Plant will provide replacement power at the Cherokee Site.
Kiewit was awarded the contract to engineer, procure and construct a nominal 300 MW 1x1 combined cycle plant and a nominal 200 MW 2x0 simple cycle plant to replace the existing steam boiler Unit 3, which will be decommissioned after the new units are in service. Equipment includes a GE 7FA.05 CTG, GE A14 STG, Vogt triple pressure HRSG, air-cooled condenser and two GE LMS 100 CTGs. The combined cycle plant will utilize the GE Rapid Response power train capability.
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.
Kiewit provided owner's engineering services to Duke Energy for their Hines Energy Complex. The scope included a technology and feasibility study and subsequent delivery of owner specifications for EPC delivery of a combustion turbine inlet chilling system.
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.
