Project Name
Upgrade Electrical Distribution System

NAVFAC Washington

The study evaluated the underground electrical distribution system for adequate sizing, improved system reliability, balanced feeder loading, ease of system maintenance, and reduced duration of power outages to buildings due to feeder failures.  

The Anacostia Naval Annex was surveyed to quantify the capacity and condition of the power distribution system serving the base, and to understand the reported system shortcomings.

The design converted the existing three feeder primary selective system into a four feeder loop system. Four existing substations that only had single feeders were modified such that they became capable of supporting the proposed loop system design.
