Hamby Young Wins $60 million Contract for 120-mile Transmission Line and Substation

Key 345kV transmission line enhances transmission network and alleviates constraints

Aurora, Ohio, September 1, 2005 – Hamby Young, a leading high voltage material packaging group in the U.S., won a $60 million contract for material procurement and logistics for construction of a 193-km (120- mile) transmission line and substation in Grimes, Iowa. Hamby Young, a Division of WESCO Distribution, Inc., was awarded the procurement contract by The L.E. Myers Co., a subsidiary of MYR Group (Rolling Meadows, Illinois). Stanley Consulting was retained to perform line design.

“This order underscores the increasing significance of the transmission line market in the U.S. and the capability of our Hamby Young Division to handle material procurement, packaging, and logistics on large, complex transmission line and substation projects with critical completion schedules,” said Don Thimjon, Vice-President, Utility Group, WESCO Distribution. “We are proud to be part of the EPC (Engineer/Procure/Construct) team with The L.E. Myers Co. and Stanley Consulting.”

The EPC contract awarded to The L.E. Myers Co. includes construction of a 345/161/15kV substation and a 345kV transmission line from MidAmerican’s Council Bluffs Energy Center (CBEC) to the Grimes substation.

Hamby Young’s procurement and logistics responsibility for the transmission portion of the project consists of 120 miles of double circuit 345kV and 161kV construction utilizing self-weathering steel monopole structures, T2-556.5 ACSR conductor, OPGW fiber optic cable with a separate static wire. The transmission assemblies primarily consist of polymer insulators in a tangent vee configuration. Hamby Young’s scope of responsibility for the 345/161/15kV substation consists of Tapered Tubular Structures, Power Transformer, Circuit Breakers, Metering, Control Panels, Station Service, Communication and other associated equipment. The buswork will be constructed in a tubular bus configuration with flexible conductor connections to all equipment.

Hamby Young’s role as the procurement arm of The L.E. Myers’ EPC team is to submit, procure, schedule, and coordinate deliveries for the above referenced scope associated with the Transmission Line and Substation. Hamby Young is also providing on-site material logistics as a part of their contract.

The project, owned by MidAmerican Energy of Des Moines, Iowa, is the result of a study conducted by MidAmerican, Omaha Public Power District, Nebraska Public Power District and other joint-owners of the new Council Bluffs Energy Center. The reliability of MidAmerican’s transmission network will be enhanced and constraints will be alleviated in and around the utility’s service territory by this project. The transmission line will also serve as an outflow connection from the new 790-MW generation facility under construction in Council Bluffs, Iowa.
