About this file
This document is a Partial One-Line Diagram (Sheet EP701) for a power generation system with microgrid capabilities at Joint Base McGuire-Dix-Lakehurst, New Jersey. The diagram depicts electrical infrastructure rated at 480Y/277V, 3-phase, 4-wire, 60Hz with 4000A capacity and 65 KAIC at the main switchboard (MC-1).
The project involves integrating multiple power generation and storage components including: a 2300 kW/2500 kVA liquid-filled transformer (XFMR-1) stepping down from 34.5 kV primary service; two 500 kW/625 kVA natural gas generators (NG-1 and NG-2); three 500 kW/500 kWh battery energy storage systems (BESS-1, BESS-2, BESS-3); a microgrid controller; and associated electrical distribution with two 30 kVA step-down transformers (MPC-1 and MPC-2) for general receptacles and site lighting. The feeder schedule specifies wire sizes ranging from #4 to #600 with corresponding conduit sizes from 1 inch to 5 inches. Contractor responsibilities include field verification of existing utilities, coordination through the Contracting Officer and 87 CES, connection of a power meter to record baseline service data for 30 days prior to equipment submittals, provision of all termination lugs, compliance with NEC requirements for grounding and conduit fill, and ensuring 100 percent rated assemblies for circuit breakers 400A and larger. The document references solicitation W912DS19D0011 and was issued in September 2026 (Revision 01) by the U.S. Army Corps of Engineers, New York District.

1. FOR GENERAL NOTES, LEGENDS, ABBREVIATIONS, AND
PHASING NOTES, SEE DRAWINGS E-001 AND E-002.
2. PARTIAL ONE-LINE DIAGRAM DOES NOT CONTAIN EVERY
ELECTRICAL PIECE OF EQUIPMENT IN B678. PARTIAL ONE-
LINE DIAGRAM SHOWS EXISTING CONDITIONS THAT HAVE
BEEN PREPARED BASED ON FIELD SURVEY DATA AND
EXISTING DESIGN DRAWINGS. ADDITIONAL COMPONENTS
AND CONDITIONS THAT ARE NOT SHOWN ON THE
DRAWINGS MAY EXIST AND MAY REQUIRE CERTAIN
ADJUSTMENTS THAT ARE NOT NOTED ON THE DRAWINGS.
FIELD VERIFY THE LOCATIONS OF ALL EXISTING
ELECTRICAL UTILITIES AND EQUIPMENT SHOWN ON THE
DRAWINGS PRIOR TO BIDDING.
3. COORDINATE ALL ELECTRICAL WORK, INCLUDING ANY
OUTAGE REQUIREMENTS FOR CONNECTIONS TO EXISTING
SYSTEMS, THROUGH THE CONTRACTING OFFICER AND 87
CES. ISOLATE WORK FROM THE EXISTING 34.5 KV PRIMARY
SERVICE.
4. AS SOON AS PRACTICAL AFTER AWARD, CONTRACTOR
MUST CONNECT A POWER METER TO THE MAIN SERVICE AT
SWGR-1 AND RECORD THE POWER FOR AT LEAST 30 DAYS.
THIS DATA MUST BE SUBMITTED TO THE 87 CES AND COR
FOR REVIEW AT LEAST SIX WEEKS PRIOR TO ANY
EQUIPMENT SUBMITTALS.
5. PROVIDE ALL TERMINATION LUGS AS REQUIRED.
6. WIRE SIZES ARE MINIMUMS. CONTRACTOR MAY INCREASE
AS LONG AS CONDUIT SIZES ARE ALSO ADJUSTED TO
MAINTAIN NEC CONDUIT FILL REQUIREMENTS.
7. ALL NEUTRAL CONDUCTORS MUST MATCH THE SIZE OF THE
PHASE CONDUCTOR.
8. ALL EQUIPMENT GROUNDS MUST BE PER NEC ARTICLE 250.
9. UNLESS OTHERWISE NOTED, ALL CIRCUIT BREAKERS
RATED AT 400A AND LARGER MUST BE 100 PERCENT RATED
ASSEMBLIES.
