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.
| 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. |
| Central Maine Power |
| Maine Power Reliability Program |
|
Sargent & Lundy is teaming with Cianbro Corp. to design and build five greenfield, open-air substations for Central Maine Power as part of the Maine Power Reliability Program. Three of the substations are 345/115/13.8-kV, one is a 345-kV switchyard ,and one is a 115/34/12-kV substation. Our scope includes complete engineering of the electrical, civil, and structural portions of the substations and specifying all of the equipment and providing procurement support to Cianbro. Also, Sargent & Lundy will be coordinating the new equipment testing at each substation, as well as writing of commissioning plans. The engineering is scheduled to be completed in early 2013, with staggered substation inservice dates starting in 2011 through 2014. Project Profile: Maine Power Reliability Programs |
| Exelon |
| ComEd |
|
Working together with Exelon's Contractor of Choice teams, Sargent & Lundy performed 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 worked 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 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. |
