Performing Phase I and II Electrical Distribution Repairs at MCB Camp Lejeune

ECC performed the Phase I and II Electrical Distribution Repairs Design-Build Project to install electrical distribution equipment and repair photovoltaic (PV) fields at Marine Corps Base Camp Lejeune in North Carolina. During Phase I, ECC replaced and/or repaired 93 electrical meters and 70 water meters with integration into Camp Lejeune’s advanced meter reading system; as well as repaired/replaced 28 backup generators and automatic transfer switches (ATS), 72 15kV Padmount transformers, and 10 photovoltaic arrays. During Phase II, ECC performed 42 backup generators and ATS replacements or new installations, new medium voltage ATS and loop feed installations, and multiple overhead to underground conversion activities. Altogether, ECC installed 20,000 feet of 15kV underground distribution lines greatly improving installation energy security and resilience. The Phase II project incorporated the first use of horizontal directional drilling (HDD) for medium voltage electrical distribution at Camp Lejeune, and using HDD, ECC was able to greatly reduce the construction footprint in high-visibility and high-use areas over that of traditional trenching and excavation methods. ECC also implemented a phased design and approval process, facilitating early procurement of long-lead equipment. ECC worked with more than 50 different project stakeholders to incorporate preferences at no additional cost to the client.
