Quanta has built a reputation for successfully and safely delivering on some of the largest and most technically complex projects in North America. When hundreds of miles of electric transmission lines need to cross the wilderness, or when massive pipelines need to connect production regions with end markets, Quanta often gets the call. We are seeing major capital projects becoming larger and extending across multiple years. Increasingly, these projects demand a full EPC solution, requiring the capabilities, resources and operational excellence that sets Quanta apart.
Quanta installed approximately 500 kilometers of parallel, 315kV alternating current transmission lines to link the Muskrat Falls Hydroelectric Generating Facility to existing power infrastructure in Churchill Falls. Upon completion, our crews moved to another related Nalcor engagement already in progress, the 1,100-kilometer Labrador Island Link transmission project.
Chino Hills Underground Transmission
Southern California Edison needed to replace existing 220kV transmission lines with new 500kV line to deliver renewable energy to the area. To minimize community impact, Quanta was selected to install the new lines underground, which included 3.7 miles of double-circuit 500kV ductbank, 42 splice vaults, 18 restraint vaults, 32 telecom vaults and nine HDD bores.
REX Zone Three Capacity Enhancement Project
To optimize an existing natural gas mainline, Rockies Express Pipeline selected Quanta to perform project management and EPC services to construct three new compressor stations and modify two existing stations. The enhancements increased the system’s delivery capacity from 1.8 Bcfd to 2.6 Bcfd.
