EPC & Design / Build
The following selection of transmission line and substation facility projects were delivered under Engineer/ Procure/Construct (EPC) or Design/Build (D/B) contracts. Sargent & Lundy participated in these projects in a number of different capacities, including prime contractor, subcontractor, and joint venture partner.
| American Transmission Company |
|---|
| Central Portfolio |
| As part of an EPC project team led by Kenny Construction Company, Sargent & Lundy is performing engineering for a group of 345-kV and 115-kV substations located in the Wausau, WI vicinity. Many of the projects are associated with the addition of 500 MW of generation at the Weston Generating Station, scheduled to come on line in 2008. Sargent & Lundy's scope of work includes support for Public Service Commission and Department of Natural Resources permits, as well as design of new and upgraded facilities. |
| East Portfolio |
| Sargent & Lundy was selected by ATC as the engineering firm for their East Portfolio, which includes Milwaukee and the southeastern region of Wisconsin. The work includes a broad range of services for new and upgraded 69-kV and 138-kV substations. S&L is also performing construction coordination, quality control surveillance, and commissioning services for a number of ATC projects. |
| Calpine Riverside Generating Station Interconnection |
| Sargent & Lundy performed complete engineering and design for the interconnection of an independent power project generating station to the American Transmission Company system as part of an EPC team. This included a 138-kV switchyard and transmission tie line. Our scope of work included electrical testing and commissioning services. Sargent & Lundy was the engineering subcontractor to M. J. Electric of Iron Mountain, MI for this EPC contract. The project was completed in 2003. |
| Calpine Corporation |
| Magic Valley |
| Sargent & Lundy was the engineer for the new 138 kV Magic Valley Switchyard in Texas and the Magic Valley power plant. This switchyard was constructed as part of the independent power project generating station for interconnection to the existing utility system. This work was performed under an EPC contract with Zachry Construction Corporation and was completed in 2000. |
| Pine Bluff |
| Under a joint venture with Zachry Construction Company, Sargent & Lundy performed the engineering and procurement activities for the Pine Bluff Power Plant and 115 kV switchyard. The switchyard interconnects the generating station project to the existing utility system in Arkansas. This project was completed in 2000. |
| El Dorado Energy |
| Sargent & Lundy was the engineer on a team that completed the 230-kV line interconnecting the El Dorado Energy Project generating station to the existing transmission system under an EPC contract with MJ Electric as the prime contractor. This double-circuit line, located in southern Nevada, was constructed on steel pole structures. Completed in 1999. |
| Enron |
| As the engineer for an EPC project team, Sargent & Lundy worked with T&D Engineering and Construction (TDEC), a division of Enron, to design the 138-kV Corinto - Leon Transmission Line. This 30-mile single-circuit line is located on the west coast of Nicaragua and interconnects a barge-mounted oil-fired generating station to an existing substation at Leon. This line was constructed using pre-stressed concrete poles with polymer line post insulators. We prepared technical specifications for material and construction, preformed detailed engineering, developed all construction drawings, and provided onsite technical support during surveying and design. Completed in 1999. |
| Exelon |
| ComEd |
| Working together with Exelon's Contractor of Choice teams led by Kenny Construction Company and Infrasource, Sargent & Lundy is performing engineering, construction quality control surveillance and commissioning services for a number of 138-kV and 345-kV transmission lines throughout northern Illinois. In addition to engineering, S&L coordinates the electrical testing and commissioning of each substation and performs construction quality control services. As Exelon's Engineer of Choice, S&L is coordinating nuclear plant switchyard modifications during refueling outages.
In addition, S&L and the COC team has been working on a series of major, enclosed substation projects for the ComEd in Chicago's central business district. Project Profile: Chicago Optimization Projects Madison and Ohio Substation Projects |
| PECO |
| Working directly as an Exelon Engineer of Choice and as part of the Infrasource Contractor of Choice team, Sargent & Lundy is designing 69-kV and 230-kV transmission lines. These projects include new lines and upgrades of existing lines. |
| SCADA Installation Programs |
| Sargent & Lundy performed engineering and design for the installation of SCADA (supervisory control and data acquisition) programmable logic controllers (PLCs) or remote terminal units (RTUs) at over 60 existing substations throughout the ComEd service territory in northern Illinois. The SCADA systems allow ComEd to improve the reliability of the transmission and distribution system and respond more quickly and efficiently to system abnormalities. This work was performed under an EPC contract. M. J. Electric of Iron Mountain, MI was the prime contractor and Sargent & Lundy was the engineering subcontractor. Our scope of work as the engineer on the EPC team included development of SCADA point lists; SCADA system engineering and design, including transformer LTC control, regulation, and tap position monitoring; schematic, wiring diagrams, and demolition drawings, preparation of material lists; and design and specification of associated equipment such as auxiliary relays, cables, conduits, and cable trays. Completed in 2001. |
| PacifiCorp |
| Wasatch Front Quantum Leap Projects |
| As part of an EPC team, Sargent & Lundy is performing complete engineering, construction, quality assurance, and commissioning services for a major upgrade of the transmission and distribution system in the PacifiCorp Salt Lake City region. The prime contractor is Kenny Construction Company of Chicago, IL. The transmission scope of work includes seven transmission projects involving a total of approximately 50 miles of 138 kV line, plus an additional 15 miles of line to accommodate the new and upgraded substation projects. The substation scope of work includes 12 new 138/12.5-kV substations and upgrades of 19 existing substations. In addition to engineering, Sargent & Lundy's scope of work includes construction quality assurance and testing and commissioning services. The majority of the projects were completed to meet summer peak loads in 2003 and 2004 and the remaining projects completed in 2005. |
| Reliant Energy |
| In association with the design of the new El Dorado generating station south of Boulder City, Nevada, Sargent & Lundy designed the 230-kV substation. The scope of our work as the engineer for this EPC contract included the complete design of a three-bay 230-kV breaker-and-a-half arrangement, specifying all equipment and providing technical interface with the connected utilities. This substation provided connections for three generating units for a total of 700 MW, with three outgoing lines to two different utilities. This project was completed in 1999.
Other work for Reliant Energy independent power projects include the Aurora 345/138 kV substation in Illinois as the engineer in the project joint venture organization and the Equistar 345/138 kV substation in Texas as the engineer in the project joint venture organization. These projects were completed in 2000. |
