ENGINE-DRIVEN GENERATOR SYSTEMS FOR BACKUP POWER APPLICATIONS
|Publication Date:||1 August 2014|
PURPOSE AND SCOPE.
This Unified Facilities Criteria (UFC) has been issued to provide guidance for the design of generator systems for backup power applications.
The information provided here must be utilized by engineers in the development of the plans, specifications, calculations, and Design/Build Request for Proposals (RFP) and serves as the minimum design requirements. It is applicable to the traditional services customary for Design-Bid-Build construction contracts and for Design-Build construction contracts. Project conditions may dictate the need for a design that exceeds these minimum requirements.
Compliance with this UFC is mandatory for the design and installation of engine-driven generator systems for backup power applications at all DoD installations. The connection of portable generator systems to a facility is covered by this UFC. Refer to Appendix E regarding portable generator connection design criteria. This UFC does not apply to:
- Tactical engine generators.
- Prime power applications. A prime power application is defined as electrical generation where there is no other source for primary electrical power. Prime power plants require specialized designs beyond the scope of this UFC; develop the design requirements for prime power plants on a project-by-project basis.
For the Air Force, Engineering Technical Letter (ETL) 13-4: Standby Generator Design, Maintenance, and Testing Criteria, defines emergency or standby generator authorizations. Design agencies are required to comply with this document.
