Quick Summary
The Department of the Army, US Army Engineer District Walla Wal, has issued an Award Notice for the sole source procurement of Lower Monumental Governor Oil Pump Unloader Valve Kits. This action is intended to update Governor Oil Pump Unloader Valve Assemblies on Main Units 1-3 of the Lower Monumental Lock and Dam's Powerhouse Generators. The award is justified to Emerson Process Management Power & Water Solutions, Inc. due to the proprietary nature of their equipment and the critical need for compatibility with existing systems. A Notice of Intent (NOI) to Sole Source will be posted on SAM.gov to allow interested vendors to respond.
Scope of Work
The requirement is for the replacement of outdated Governor Oil Pump Unloader valve assemblies with retrofit kits. These kits must incorporate time-delay electronic relays compatible with existing Pelton governor oil pumps and the US Army Corps of Engineers' (USACE) American Governor Company (AGC) digital control system. Specific deliverables include:
- Dual Unloader Assembly Kits (compatible with Pelton C310 Main Pumps) - First Unit (1) and Follow-on Units (2).
- Single Unloader Assembly Kits (compatible with Pelton C90 Jockey Pumps) - First Unit (1) and Follow-on Units (2).
- Unloader Spare Parts Kit (1).
Contract Details
- Contract Type: Firm-Fixed-Price (FFP) supply contract.
- Delivery: All items must be delivered within 20 weeks of contract award.
- Set-Aside: Not applicable, as this is a sole source justification.
- Notice Date: April 16, 2026.
Justification & Market Research
Emerson is identified as the only company capable of providing compatible retrofit kits because they purchased the patents from AGC and Pelton. The existing unloader valves are 55 years old and require frequent maintenance. The government conducted market research and found no alternatives that meet requirements without significant redesign and cost. The new digital unloaders are expected to increase capability and efficiency, extending the useful service life of the governor oil pressure pumps by approximately 20%.
Additional Notes
This document serves as a justification for the sole source procurement. A formal Notice of Intent to Sole Source will be posted, allowing other vendors to demonstrate their capability to meet the requirements. The previous contract for similar services (W912EF-17-P-0066) was awarded competitively but is now considered a sole source requirement due to Emerson's proprietary software.
