This is a technical construction plans document for the Swedwood 69/15 kV Substation project in Danville, Virginia, prepared by Utility Engineering, LLC and issued for bids on August 31, 2026. The project encompasses a complete electrical substation design package including a general arrangement plan, grounding system design, detailed equipment specifications, and cross-sectional details. The substation is designed to operate at 69 kilovolt (high voltage) and 15 kilovolt (low voltage) with multiple incoming transmission lines from Airside, Cyberpark, and AEP sources. Key infrastructure components include two main transformers (T1 and T2) with load tap changer capability ranging from 15/20/25/28 MVA, multiple 72.5 kV and 15 kV circuit breakers, a 40' x 11.5' control house, station service transformers, surge arresters, voltage transformers, and an extensive grounding system with 10-foot sectional Copperweld ground rods and 4/0 AWG bare copper wire at 36 inches depth. The site includes a perimeter security fence with gate access and eight 15 kV underground feeders. The overall substation layout covers approximately 215 feet in length and 177.5 feet in depth, with equipment arranged according to RUS Bulletin 1724E-300 design standards for spacing and clearances.

The grounding design specifications include detailed connection methodologies utilizing Anderson & Fargo connectors, exothermic connections for permanent installations, and comprehensive bonding of all equipment and structures to the main ground grid. The plans specify vertical clearance requirements per NESC Part 124A3, mandating minimum 8.5-foot clearances to energized equipment for worker safety. All conductor spacing and equipment arrangements follow established design standards for 69 kV and 25 kV outdoor switchgear, with voltage insulation levels of 350 kV BIL for 69 kV equipment and 150 kV BIL for 25 kV equipment. The document indicates these plans were submitted to the client on August 31, 2026, with the status marked as "Issued for Bids." The drawings are designed for full-size plotting on 24" x 36" sheets and include comprehensive notes regarding future material expansion (shown in gray) versus new construction materials (shown in black).
