OUC System Design & Hardening Standard

Construction Standards

– 80% of new distribution construction is underground – Transmission and Distribution facilities are constructed to NESC 120 mph extreme wind loading standards (NESC 140 mph extreme wind loading at the coast) – Ensure “foreign” utility attachments meet OUC design and wind loading standards – Loop Design distribution underground circuits – Redundant circuits to key critical customers with automatic transfer scheme – All new and replacement transmission poles are steel or concrete
