Georgiana Substation - Alabama Power – Birmingham, Alabama
This project involved the upgrade of an existing 115-44-15kV substation. Replacement of existing cap & pin insulators with station post; replacement of 600A switches with new 1200A switches; added Station Class Arresters on load side of 44-15kV transformer; raised 15kV structure to obtain proper live to personnel clearances and increased phase to phase spacing; new ground grid; generated Bill of Material for all items.
Northern Virginia Electrical Cooperative – Manassas, Virginia
NOVEC required the steel design and bidding of a three transformer bank, eight feeder positions with high side “A’” frame and circuit switchers. Total weight of steel was 74,594#.
Chesterfield Substation - Lynches River ECI – Lancaster, South Carolina
Modifications to an existing 69-15kV substation, including adding a 69kV, S&C model 2020 Circuit Switcher on a constrained site. Also added protective relaying and DC power in an outdoor cabinet.
Sawnee Electrical Membership Corporation – Cumming, Georgia
New 25kV switching stations typically with either five or eight lowside positions. Developed standardized layout and standardized steel design to reduce overall cost.
Flaherty Substation - Meade County RECC – Brandenburg, Kentucky
Design layout of a 69-13.2kV, relayed substation with four feeder positions, source side “A” frame, transformer oil containment pit, and control house.
Bolins Mill Substation - Buckeye RECI – Rio Grande, Ohio
Design layout of a 138-15kV relayed substation with box type four feeder positions, source side “A” frame, transformer oil containment pit, and control house.
Dumplin Valley Substation - Appalachian EC – Jefferson City, Tennessee
This project consisted of the design layout of a 161-69kV, 69kV ring bus relayed substation with four 69kV “A” frame feeder positions. Dual 161kv feeds from a TVA station , transformer oil containment pits, and control house.
