Marine Corps Base Camp Lejeune
Camp Johnson Microgrid
2
• Primary function: Training area of base, seven (7) separate training efforts
• Peak load: 4.3 MW
• Average Load: 2.5 MW
• Existing distributed generation/utilities: • PV – two sites (920KW, 787KW)
• 14 diesel generators
• rebuild substation
• 6” natural gas line
• End goal: ability to remove Camp Johnson from commercial power and support the entire load on distributed generation
Project Assumptions
3
• 23kV Duke à 12.47kV Duke substation à installation owned switching station
• Utilize existing PV, natural gas utility availability
• Add battery energy storage (BES) system to provide seamless transition from commercial to distributed generation
• Add natural gas generation to support entire load of Camp Johnson
• Control scheme to allow testing, load shedding, fault detection automatic transfer
BASE OWNED
Project Identification
4
Original Project: Awarded as a 2018 Energy & Resilience Conservation Investment Program (ERCIP) project for solar panels (ERCIP = MILCON subset intended to improve energy resilience)
Change Request: Submitted in mid 2019 to change from efficiency based project to resilience based project, approved end of calendar 2019
• Energy program shift from energy efficiency to energy resilience and security • No longer a good fit, required redesign – height of sunshades• Hurricane Florence
5
• Energy program shift from energy efficiency to energy resilience and security • Followed by Marine Corps Energy Security Policy• DON P-602 Three Pillars of Energy Security
• No longer a good fit • Other Marine Corps installation had similar project that required redesign
• Kalmar move work vans, increased height requirement• Increased height requirement = structural improvements to meet hurricane wind requirements• In review with tenants, possible interference with daily forklift activity• Overall good project, but too many changes required for our installation
• Hurricane Florence and other Commercial Outage Impacts• Camp Johnson is fed from a local utility distribution radial feed, which means that the base is
susceptible to outages caused by events outside of the base borders. • Camp Johnson is home to entry, intermediate and advanced level officers training, enlisted and
civilian students in Personnel Administration Train the Trainer School, Ground Supply Support and Distribution, Financial Management and Logistics Operations, Water Survival.
• Delays in training directly impact Marine Corps mission• 11 day outage at Camp Johnson• Commercial rerouting to hospital

• Base takes primary control of project management • NAVFAC project management – Marine Corps ERCIP process • Installation not experienced with microgrids – stay highly involved in process• DB vs DBB• Contract through local A&E IDIQ
• IDIQ A&E with electrical designer, familiar with other work on installation
• RFP either through utility or General, Electrical MACC, or GSA

Energy Program Future
12
• Resilience – ability to recover from commercial outage, reduce dependence on external suppliers• Energy security – ability to meet critical and total energy requirements under
normal operating conditions and in the event of 14-day outage• Installation Energy Security Plan (IESP)
• Comprehensive analysis of existing utility infrastructure• Fuel sources• Distributed generation• Identify gaps in energy security
• Reliability - modernize infrastructure to ensure secure and reliable energy and water supplies to support mission
• Efficiency – utilizing minimum energy and water required to support mission
