AoI 5.4 Supply and Install Temporary Generator Controls - KCS.pdf

Commercial Solution Opportunity – Defense Commissary Agency (DECA)

In accordance with the Commercial Opportunity Solution – Defense Commissary Agency

(DeCA), dated 04.10.2026, paragraph 5.0, the following specific requirement in support of AoI

5.4 Lower Costs is attached.

The Defense Commissary Agency (DeCA) is seeking innovative, commercial approaches from

European Union registered firms for industrial temporary generator controls at the Central

Distribution Center on Ramstein Air Base, Germany supporting operations within the European area. This purchase is for an industrial temporary generator controls to replace an existing backup power system non-operable electrical switchgear. The goal is to leverage industry best practices, modern technologies, and creative service models to improve reliability, accountability, and overall service quality for CDC electrical backup power systems. Equipment and approach will undergo vigorous inspections at all stages (installation methodology prior to work performance, material delivery, material install, commissioning) by the Technischer

Überwachungsverein (TUEV Saarland) in alignment with commercial practices followed by the

Deutsches Institut für Normung. The timeline for performance is 10 weeks total from award until commissioning by the TUEV. Attachment 1 contains technical data that will provide assistance in understanding current conditions that commercial solution proposal will need to meet.

Our objective is to build and install temporary generator controls for the two existing

Cummins generators. Interested vendors with proven expertise in providing temporary generator controls equipment should submit their Commercial Solution Proposal (Phase 3) in accordance with section 3.4 Commercial Solution Proposals.

The closing date for this opportunity is Tuesday, 28 April 2026 at 12:00 PM Central European

Time (CET). Award is contemplated on or around 1 MAY 2026 as the rental generators currently in place (that this requirement will replace) have limited performance remaining.

All communications to include questions pertaining to this opportunity shall be sent via email to the following Points of Contact:

PROJECT: Temporary Control Solution for Existing Generator System

ISSUE: The problem lies exclusively in the generator control system, including both the dedicated local control and the higher-level / supervisory control system. The system is inoperable.

SOLUTION: A temporary solution is required for the generator control system of the existing emergency power installation.

Current Site Conditions:

The site is equipped with two existing generators, and both units are operational. A load bank test has already been carried out successfully, confirming that both generators are functioning properly.

The existing installation consists of:

• 2 x Cummins C900D5 generators

• equipped with HC634H alternators

• inventory numbers: CDK 000365 and CDK 000366

Expected Proposal to provide information on the technical solution:

Seeking the temporary solution to include:

• a temporary replacement for the existing generator control system

• the local generator control

• the higher-level / supervisory control

• the interface and communication with the circuit breakers

• all required components for a proper and reliable temporary operation

• 24/7 hotline / emergency support availability, so that in the event of a power failure, immediate support and switching can be ensured

Seeking a solution from the same manufacturer as the existing equipment (CUMMINS GENERATORS), or a preferred service provider experienced with paralleling Cummins Generators. The purpose of this request is to obtain commercial solutions for a temporary control solution that restores proper coordinated operation of the emergency power system until a permanent modernization or replacement is implemented.

Trier, den 26.03.2026 Netzersatzanlage: 2 x 910 kVA / Funktionsprüfung

Untersuchungsbericht Funktionsprüfung der NEA

Aufgrund der Störung an beiden Aggregaten wurden wir beauftragt eine Funktionsprüfung der Netzersatzanlagen ohne Steuerung durchzuführen.

Das Ziel soll sein die Funktion der Aggregate zu testen, um festzustellen ob die Aggregate die geforderte Leistung liefern.

Der Lastlauftest mit mobilen Lastwiderstand ist ebenfalls Bestandteil des Auftrags.

Funktionsprüfung am 16.03.2026

Nach Ankunft unser Technischer waren die Aggregate außer Betrieb.

Es wurde zuerst Aggregat Nr. 2 getestet.

Nach erstem Startversuch war die Spannung und Frequenz unstabil und das Aggregat ging aus. Wir haben die Kraftstoffzufuhr überprüft und festgestellt, dass das Magnetventil in der Kraftstoffzuleitung elektrisch geschlossen war, da keine Anforderung aus der NEA-Steuerung (außer Betrieb) vorlag.

Wir haben das Magnetventil direkt bestromt bzw. manuel geöffnet und haben dadurch die Kraftstoffzufuhr ermöglicht.

Nach erneutem Versuch hat das Aggregat gestartet und stabile Spannung und Frequenz geliefert.

Nach Anschluss der Lastbank wurde der Lastlauftest in verschiedenen Stufen von ca.

20% bis 110% in Zeitabständen von ca. 15 Minuten einwandfrei ohne Funktionsstörungen durchgeführt, siehe Lastlaufprotokoll Generator 2.

Im Anschluss wurde auch der Generator 1 konform der Prüfung des Generator 2 getestet, siehe Lastlaufprotokoll Generator 1.

Beide Aggregate laufen stabil und liefern die Leistung, die auf dem Typenschild steht
