Sign In Sign Out. Maintain 25 km of overhead or ground-laid secondary distribution line. Appendix A contains a discussion of power-generation concepts. AFCS is discussed in Chapter 4.

FM Table of Contents

Construct or repair meters of ground-laid secondary distribution line per day. NTGs require site preparation for installation. The indispensable nature of electrical power compels commanders and planners to recognize their electrical power needs and to ensure that those needs are met. They provide a mobile source of power to units operating in the field.

Prime power units have a limited capability to operate, maintain, and perform damage assessment of some fixed commercial power plants, especially diesel-engine- and gas-turbine-driven plants.

The team can configure its generators into one large power plant or two smaller plants. These power systems are part of the infrastructure, as are other utility systems. The prime power unit provides power-related technical advice to the appropriate engineer staffs.


These power systems may be encountered in factories or other production plants where large quantities of power are required to operate heavy machinery. This function is performed by the vertical construction platoon of the combat-heavy, engineer-battalion line companies and by engineer utilities detachments.

This is roughly equivalent to the distribution system of a small rural town. Prime power may be employed as a stand-alone power source. Make 20 connections per day to service equipment, load centers, and the secondary side of pad-mounted distribution transformers. Prime power units have a limited capability to maintain overhead distribution systems.

The design includes sizing of conductors, breakers, switches, transformers, load centers, and other devices. Responsibility for providing, operating, and maintaining the generators lies with the user. During operations short of war, the primary objective of prime power operations is to provide prime power generation and power-related technical support to forward presence operations, contingency response, and disaster relief.

The prime power unit also designs f, ground-laid distribution systems.

From the military perspective, electrical power encompasses the entire spectrum of power generation, distribution, and transmission systems that support military operations. This includes making in-line splices but does not include making connections to distribution transformers, load centers, or service equipment. Chapter 4 provides detailed information on prime power missions and capabilities.


Commercial power plants and their associated transmission and distribution networks are fixed nonstandard systems. The completed design includes circuit diagram and site layout drawings or sketches, a complete bill of materials BOMestimated work requirements, and construction time.

The mission of engineer prime power units is to generate electrical power and provide advice and technical assistance on all aspects of electrical power and distribution systems in support of military operations.

Chapter 4 contains information on the three modes of power generation. Engineer prime power units support sustainment engineering efforts by providing reliable power generation and power-related technical expertise. Prime power may be supplemented with portable commercial generation equipment when it is available.

Make 4 connections per day to the primary side of pole-mounted transformers. Without it, many crucial systems cease to operate.

The units’ power-generation capability allows them to Commercial power is provided in the theater by the host nation vm nations. Enter Your Email Address.
