Energy Action Month

October is Energy Action Month! One of the priorities of the Expeditionary Energy Office is to discover innovative power technology solutions to support the dismounted warfighter. Conserving energy on a marine to reduce weight can make all the difference on the field. Marines and leaders, please take THIS SURVEY to share your experience and provide insight to our future power energy efforts.

E2O Conducted The First of Two Limited Technical Assessments (LTA) for the Mobile Amphibious Assault Fuel Distribution Initiative
  • These LTAs validated the capability to transfer bulk liquid between storage containers installed within an Improved Navy Lighterage System (INLS), containers on the deck of a Landing Craft Utility (LCU), and Dracone fuel storage systems via a maritime buoy pump.
  • This Joint LTA was held at Naval Amphibious Base in Coronado, CA and was supported by Naval Beach Group 1 (NBG-1), Expeditionary Warfare Training Group Pacific (EWTGPAC), Amphibious Construction Battalion 1 (ACB-1), and Assault Craft Unit 1 (ACU-1).
  • E2O will conduct a second LTA at NAB Coronado, CA to demonstrate the capability to transfer bulk liquid between these Navy craft and a marine Corps bulk fuel unit situated on the beachhead. For more information on the LTA2, see the Inside Defense Article.

3/2 Marines Utilizing GREENS during ITX
  • Marines with 3rd Battalion, 2nd Marine Regiment (3/2) utilized the Ground Renewable Expeditionary Energy Network System (GREENS) at Camp Wilson, Twentynine Palms, CA during the Integrated Training Exercise (ITX).
  • For a week before receiving generators from the ITX issue point, 3/2 powered vital equipment utilizing GREENS.
  • Following receipt of generators, a Quonset hut providing relay switches lost power and the GREENS continued to provide power to that building for uninterrupted operations.
