Project Description• What?
115kV substation (switchyard)• Where?
Hypothetical location on Iowa State campus• Why?
To accommodate a hypothetical new wind farm• When?
Immediately (utilizing tried and true current tech)• How?
Act as a contract team

Requirements• Design services
– Layout will allow for future expansion– 125 Volt Station Battery supply for station service
outage– Fiber-Optics communication between substations – The substation be designed with Iowa weather in
mind• Safety
– Clearance for emergency vehicles – Clearance for removal of defective parts– Ground grid capable of handling a fault
• Follow industry and company standards
