The design includes sizing of conductors, breakers, switches, transformers, load centers, and other devices. Maintain 25 kilometers km of overhead or ground-laid primary distribution line.

FM – Engineer Prime Power Operations –

Prime power teams can construct and maintain temporary, ground-laid or buried primary and secondary distribution systems. NTGs require site preparation for installation. In addition to developing specifications for contracts, prime power personnel also help perform the technical evaluation of the bids that are received. Engineer prime power units provide nontactical power generation and power-related technical expertise in support of operations across the continuum of military operations.

This mission statement encompasses military operations across the entire continuum of military operations to include disaster relief, humanitarian assistance, and other operations short of war.

Prime power personnel can make connections to existing distribution networks. Prime power operations are conducted by engineer prime power units. They provide a mobile source of power to units operating in the field. For more complex projects, a critical path method CPM diagram is also produced. Electrical power is an essential element of military operations.

Chapter 4 contains information on the three modes of power generation. Maintain 10 km of buried secondary distribution line. The team can install and operate these plants in any of three modes. Command, control, communications, and intelligence C 3 I functions are highly reliant on dependable electrical power.


Once installed and operational, these generators should be turned over to the supported unit to operate and maintain, thus freeing the prime power team for additional missions.

This is useful in determining how much power is available on a system and whether the system is expandable or not.

Construct or repair meters of ground-laid secondary distribution line per day.

Appendix A contains a discussion of power-generation concepts. Commercial power plants and their associated transmission and distribution networks are fixed nonstandard systems. The use of prime power usually requires the construction of nonstandard distribution networks to take power to the users who need it.

Chapter 4 provides detailed information on prime power missions and capabilities. The prime power team conducts a load survey to determine the amount of f a supported unit needs and what the distribution requirements are. The load survey is a vital preliminary step in providing prime power support.

These power systems may be encountered in factories or other production plants where large quantities of power are required to operate heavy machinery. Service equipment, which is installed by interior electricians, is the main 54-22 panel or switched fuse box inside the structure. Construct or repair 5-22, meters of ground-laid primary distribution line per day. 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.


In some cases, nonstandard generators may already be installed as backup. Supported units may use contracting channels to rent or lease these generators. In all cases, the prime power team should work with indigenous power-plant operators or contracted technicians who are familiar with the power plant. Each prime power team is equipped with four kW generators, giving the team a 3-MW gm power-production capability. Design calculations include 5-4222 drops as a result of line loss and grounding requirements.

Prime power units use these off-the-shelf designs where applicable. When installed in parallel with commercial power, prime power can be used for either load tm or standby. They can also install, operate, and maintain nonstandard, portable power-generation equipment and operate and maintain some fixed commercial power plants.

Because the prime power teams have working knowledge of multiple power systems, they are able to repair, maintain, and operate industrial power systems and their associated controls. Workload estimates for these tasks, which are provided below, are for planning and estimating purposes only and are highly dependent on controlling variables. The portion of the continuum that is exclusively prime power represents power generation and distribution accomplished f, prime power units with their organic equipment.

Continuous operation of large fixed plants exceeds the manpower capabilities of the team. During war, the primary objective of prime power operations is to support force sustainment in the communications zone COMMZproviding power generation and power-related technical support to rear-area units, 5-4222, and activities.
