EURO-DIESEL DRUPS (DIESEL ROTARY UNINTERRUPTIBLE POWER SUPPLY)
DEPT OF DEFENSE.DEPT OF THE ARMY.AMC.ACC.ACC-OO.411TH CSB.0906 AQ CO DET B CONTRACTI · Response deadline: Mon, 30 Nov 2026
What the government is buying
The U.S. Army is soliciting bids for EURO-DIESEL DRUPS equipment—that is, Diesel Rotary Uninterruptible Power Supply systems. DRUPS technology combines a kinetic energy flywheel with a diesel engine to provide continuous, conditioned power without the delays or switching losses of traditional battery-based UPS systems. These systems are commonly used in critical facilities—data centers, military installations, medical complexes, and other environments where even momentary power interruption is unacceptable.
The specific DRUPS model referenced is manufactured by EURO-DIESEL, a Belgium-based company specializing in this integrated power protection technology. Rather than relying on batteries for short-term bridge power, DRUPS units store kinetic energy in a rotating mass; during a utility outage, the flywheel immediately supplies power while the diesel engine starts and takes the load. This procurement appears focused on acquiring or leasing this specialized equipment, though see the solicitation for exact specifications, quantities, and whether this is for purchase, lease, or service-inclusive arrangement.

Who can bid
This solicitation is full and open competition with no small business set-aside, meaning any qualified offeror—large or small business—may compete. The relevant NAICS code 811310 is "Commercial and Industrial Machinery and Equipment (except Automotive and Electronic) Repair and Maintenance." Businesses registered under this NAICS should verify their SAM.gov profile accuracy.
Given the specialized nature of DRUPS equipment, experience with critical power infrastructure, flywheel-based UPS systems, and medium- to high-voltage electrical systems will likely be weighted heavily in evaluation. See the solicitation for any specific experience requirements, past performance references, or mandatory qualifications such as ISO certifications, factory-authorized representation, or security clearances.
How to put together a competitive bid
Since this is unrestricted competition against potentially large, experienced firms, small businesses should emphasize specialized expertise and direct manufacturer relationships. Consider these steps:
Secure manufacturer partnership or authorization: If you are not a EURO-DIESEL factory representative, contact the manufacturer immediately regarding dealer, distributor, or teaming arrangements. OEM authorization is often mandatory for critical power equipment solicitations.
Demonstrate relevant past performance: Identify contracts for DRUPS, rotary UPS, or comparable critical power systems (e.g., static UPS above 500 kVA, diesel-generator integration projects). Military or federal past performance is preferable; commercial data center or healthcare use cases are relevant alternatives.
Address lifecycle and sustainment: DRUPS systems require specialized maintenance—flywheel bearing service, diesel engine overhaul, kinetic energy system recalibration. Propose a comprehensive solution including spare parts, technical manuals, training, and long-term support if the solicitation permits.
Time zone awareness: The 1:00 PM JST deadline suggests Asia-Pacific theater relevance. Confirm your ability to meet this deadline accounting for time zone conversion, and verify whether site visits, inspections, or in-person presentations overseas are required.
Price strategically: Without set-aside protection, price competitiveness is essential. Obtain detailed equipment pricing from EURO-DIESEL and factor import logistics, customs, and any ITAR or EAR compliance costs.
