Project Detail

Cedar Creek Wind Farm

March progress 03-13-07 job 6044-4 003   Helicopter_0311   Substation_0423

Location:  Colorado

Description:  This EPC project consisted of the construction of 73 miles of 230kV transmission line including the design, purchasing and material management.  The H-frame structures were a hybrid of concrete and steel with vertical bundled 954 ACSR and two 3/8″ static lines.

The project also included the construction of a new 230/34.5kV interconnect switching substation that included two 60 MVA transformers, two capacitor banks, circuits, switches, meters, site work and concrete foundations.

Construction took place during the worst Colorado winter in fifty years. Great Southwestern performed engineering, procurement and construction on a fast track schedule beginning engineering in June 2006 in conjunction with route selection and acquisition and construction completion in August 2007. There were multiple crossings over high voltage lines, highways, and a river crossing. Sandy terrain resulted in difficult conditions that required matting to access structure locations. Sensitive environmental and permitting issues required a significant amount of coordination.
