About this file

Written by GovTribe AI · Mar 14, 2025

The document is a set of construction drawings for the Three Mile Substation Control Building Upgrades project for the Northern Wasco County Public Utility District (PUD) located in The Dalles, Oregon. The project involves constructing a new control building for a substation, with detailed technical drawings spanning multiple volumes including foundation plans, electrical schematics, conduit layouts, grounding plans, relay panel designs, and interconnection diagrams. The drawings are prepared by Stoddard Power Systems and dated July 2023, with revisions noted through May 2024.

The technical drawings provide comprehensive engineering specifications for a complete electrical substation control building, including detailed plans for 115kV and 69kV systems, transformer and circuit breaker controls, relay panels, grounding systems, and auxiliary electrical infrastructure. The project appears to be a significant upgrade to the existing substation's control infrastructure, with precise engineering drawings covering electrical interconnections, control schematics, panel layouts, and structural details. The drawings indicate integration of modern protection, control, and monitoring systems, suggesting a comprehensive modernization of the substation's electrical control capabilities.
