Y--COTP Series Capacitor Two-Phase Design Build

The Western Area Power Administration (WAPA) issued an amendment extending the proposal due date for the California‑Oregon Transmission Project (COTP) Two‑Phase Design‑Build, focused on replacing a 525 kV series capacitor bank. This design‑build effort will involve engineering, procurement, and construction of the new capacitor bank, with the intent to improve reliability and performance of the transmission system. The amendment pushes the submission deadline to mid‑November 2026, giving contractors additional time to finalize proposals. • Scope: Full design‑build of a 525 kV series capacitor bank replacement, two‑phase configuration. • Location: California and Oregon transmission corridor under the COTP. • NAICS: Primary classification 237130 (Electrical Power Transmission & Distribution). • Deadline: Extended to 13 Nov 2026; original posting was 20 Oct 2026. • Primary contact: Jolene Daoud (WAPA) for clarification and submission logistics.
