ENCL D_Utilities_P1238.pdf

These are ArcGIS Web Maps for a utility infrastructure project at Marine Corps Air Ground Combat Center (MCAGCC) in Twentynine Palms, California. The maps show detailed geospatial information with multiple color-coded overlays (yellow, purple, green, blue) indicating different utility or infrastructure zones across a desert terrain. Each map provides precise GPS coordinates, grid references, and spatial boundaries, with an aerial/satellite view background showing the surrounding desert landscape and mountainous terrain. The maps are dated April 18, 2025, and were created for the United States Marine Corps to support the Battery Energy Storage Systems (BESS) project (P-1238) for grid stability and energy resiliency.

The maps appear to be part of the technical documentation for a 10 MW Battery Energy Storage Systems project, which includes designing and constructing battery storage units at two locations on the military base. The project involves installing approximately 30 standalone modular battery units that will be connected to solar photovoltaic arrays and the installation's electric distribution system, with the goal of improving grid reliability, supporting black-start and islanding events, and reducing energy costs through strategic power management.
