Indianapolis Power and Light Company (IPL) provides electric service to more than 470,000 users in the area and surrounding communities, with Petersburg and Harding Street Plants, the company’s two biggest plants, accounting for a majority of that generation. In order to meet EPA Mercury and Air Toxics Standards (MATS) compliance, IPL is retrofitting five units at these sites with new environmental control equipment.
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.
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 teamed with the owner early in the Langley Gulch Power Plant development to create a baseline, self-build proposal that was evaluated against outside competitors. Kiewit worked closely with the owner to develop a cost-competitive project.
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.
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.
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.
Kiewit was awarded the contract for engineering and procurement for the Napanee Generating Station in Napanee, Ontario. The 970 MW gas-fueled facility will provide reliable on-demand power to local homes, schools and businesses as well as replace existing coal-fired power in the providence.
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 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.
