Quick Summary
The Department of the Army / W076 ENDIST TULSA has issued a Special Notice / Request for Information (RFI) seeking industry feedback on potential commissioning options for the Webbers Falls Excitation System Replacement project in Webbers Falls, OK. The RFI aims to gather insights on contracting strategies, risks, costs, and warranty considerations for replacing excitation systems on three units. Responses are due by March 3, 2026.
Purpose
This RFI is for market research purposes, specifically to solicit industry feedback on various options for commissioning the excitation system under a proposed contract action. The Government is considering different approaches and seeks expert opinions to inform its contracting strategy, minimize risk, optimize cost, and understand warranty implications for the replacement of excitation systems on three generator units.
Scope of Work
The project involves the replacement and installation of several key components for the excitation systems, including:
- AC Supply Connection: Replacement of cable/conduit for Unit 1 bus tap to PPT high side fuse disconnect.
- Power Potential Transformer (PPT): Replacement with a new PPT.
- PPT to Exciter AC Connection: New close-coupled configuration.
- Exciter Cabinets: Replacement of all exciter cabinets with specified size, redundant bridges, and controllers.
- Exciter DC Field Connection: Replacement with new DLO cable and conduit.
- Collector Ring: Inspection with optional refurbishment.
- Field Ground Detection: Installation of new SEL-2664 modules and fiber optics.
- Control Room Switchboard Devices: Replacement of two exciter control switches per unit, installation of new Satellite Clock.
- Annunciation: Connection of exciter MODBUS signals to plant annunciation system; installation of new "Exciter Trouble" light.
- Data Connections: Provision of Modbus RTU (RS-485).
- Wiring: Contractor to supply and pull new cable for internal connections.
- Commissioning and Testing: Detailed in specific paths, including NERC Model Verification Testing for Units 2 & 3.
Commissioning Option Paths for Feedback
The RFI presents four distinct commissioning options for industry review:
- Path 1a (Two Contracts): First contract for scope completion on all units (Units 2 & 3 fully commissioned, Unit 1 partially tested), followed by a second sole-source contract for Unit 1 commissioning.
- Path 1b (One Contract - Rolling NTP): A single contract for all units, with a delayed Notice to Proceed (NTP) for Unit 1 (up to 5 years).
- Path 2 (One Contract - Unit 1 using Unit 2 Gen): A single contract for all units, where Unit 1 commissioning utilizes Unit 2's generator and associated cabling.
- Path 3 (Two Contracts - Sole Source for Unit 1): First contract for Units 2 & 3, with a second sole-source contract for the entire Unit 1 excitation system.
Questions for Industry
Respondents are asked to address specific questions regarding each path, including:
- Warranty start dates.
- Risk assessment.
- Identification of unbiddable paths and reasons.
- Cost estimations.
- Recommendations.
- Any unconsidered commissioning options.
- Paths that would produce the most accurate bid price.
