Project Manager Expeditionary Energy and Sustainment Systems

Tuesday, August 22, 2017

What is it?

Project Manager Expeditionary Energy and Sustainment Systems (PM E2S2) is the Army’s project management office that provides integrated materiel solutions, force sustainment support, and contingency basing designs to Joint Warfighters across the full range of military operations.

PM E2S2 is the lifecycle manager for multiple combat support and combat service support capabilities which include: power generation and power distribution; field feeding and field services; shelters and environmental controls; aerial delivery systems; and contingency base engineering design support.

What has the Army done?

On Aug. 3, 1967 then, PM Mobile Electric Power, now PM Expeditionary Energy and Sustainment Systems was chartered to serve as the Department of Defense Lead Standardization Activity responsible for providing a modernized family of mobile electric generator sets throughout the services. In 50 years PM E2S2 continues to expand its role in the Army as a lead integrator of operational energy solutions across multiple combat support systems.

PM E2S2 provides the Joint Warfighter with a variety of combat support solutions including:

  • Force Provider Expeditionary Modules: A containerized life support system for contingency base camps.
  • Advanced Medium Mobile Power Sources: The 3rd generation of mobile electric power systems that provide fuel efficiency, noise and weight reductions.
  • Improved Environmental Control Units: Provides cooling, heating, and dehumidification for Army operating systems.
  • Power Distribution Illumination Systems: Comprises of standardized electrical power distribution devices.
  • Joint Precision Aerial Delivery Systems: An autonomously guided container delivery system.

What continued efforts are planned for the future?

PM E2S2 is collaboratively shaping emerging technologies to help the Army achieve its Net-Zero objectives:

  • Developing advanced shelter designs (insulation, shading and environmental controls); waste water management (reduction/elimination) and fuel reduction
  • Developing the next generation of intelligent power management systems/microgrids
  • Actively providing contingency base infrastructure engineering design support to theater planners and the combatant commands
  • Continuing to provide enduring materiel solutions in support of worldwide deployments via Army Prepositioned Stocks
  • Developing options for a man-portable battery recharging power source

Why is this important to the Army?

PM E2S2 helps the Army to develop and procure operational energy solutions that saves lives, avoids costs, and returns combat capability to the Warfighting Commanders. The Army Operating Concept calls for “Advanced and efficient power saving and generation technologies will reduce sustainment and lift requirements” (para C-2a3). For the past 50 years, PM E2S2 has worked to field materiel solutions that help minimize the logistical footprint on the battlefield. That means less fuel convoys in harm’s way; freeing Soldiers up for higher priority combat missions.
