Copco #2 115/69 kV Substation
Siskiyou County, CA
DEA was contracted to prepare a scope and to design the rebuilding of an existing 115 kV/69 kV yard from a radial bus configuration to an initial ring-bus configuration with an ultimate break-and-a-half configuration. The project included the addition of one 115 kV/69 kV autotransformer, two generator step-up transformers, metal-clad switchgear, and a control house. In addition, an onsite fuel station, two metal storage units, and a wood barn had to be relocated. The design also required modifying the yard and access road for the potential use of a mobile transformer.
As the engineering design consultant, DEA provided a range of services:
- Project scoping support
- Physical design
- One- and three-line diagrams
- Foundation design
- Structural design
- Site grading and drainage design
