About this opportunity
The Department of the Army Corps of Engineers Portland District awarded a supply contract to Eaton Corporation on May 6, 2026, for the manufacture and delivery of ten custom 15 kilovolt Main Unit Breaker Switchgear Assemblies for Bonneville Powerhouse 1.
The assemblies will replace existing oil circuit breakers over 80 years old that are obsolete and no longer maintainable. Eaton previously served as Designer of Record under Contract No. W9127N-15-C-0002, during which it designed, fabricated, and tested a prototype switchgear assembly with full-scale design testing. This procurement supplies ten units identical to that Government-accepted prototype design. The new assemblies, including draw-out circuit breakers and disconnect switches, must fit within existing spatial constraints at Powerhouse 1 (Elevation 65) on the Columbia River. Scope is limited to manufacture, testing, and delivery only; installation and removal of existing equipment will be performed by Government personnel under separate efforts. No set-aside was used for this award.
Notice text
1.0 Background
The Bonneville Lock and Dam is a federally operated hydroelectric facility located on the Columbia River, constructed in the 1930s. The facility plays a critical role in providing renewable energy, supporting regional navigation, and contributing to flood risk management throughout the Pacific Northwest.
This requirement supports the replacement of ten (10) existing Main Unit oil circuit breakers at Powerhouse 1, which are over 80 years old. The existing switchgear is obsolete, no longer maintainable, and presents a significant risk of operational failure.
Eaton Corporation serves as the Designer of Record (DOR) for this requirement under prior Contract No. W9127N-15-C-0002. Under that effort, Eaton designed, fabricated, and tested a prototype switchgear assembly, including full-scale design testing. This procurement leverages the previously developed and Government-accepted design and associated test data.
2.0 Objective
The objective of this contract is to procure, on a supply-only basis, new custom-manufactured switchgear assemblies to replace the existing obsolete equipment.
3.0 Scope of Work
The scope of this contract is limited to the manufacture, testing, and delivery of ten (10) new custom 15kV Main Unit Breaker Switchgear Assemblies. These assemblies, including draw-out circuit breakers and disconnect switches, shall be designed and manufactured to fit within the existing spatial constraints at Bonneville Powerhouse 1 (Elevation 65).
This is a supply-only contract. The scope does not include on-site labor, removal of existing equipment, or installation of the new assemblies. All installation and associated construction activities will be performed by Government personnel under separate efforts.
