Northeast Energy Center LLC (NEC) selected Weston & Sampson to be the Owner’s Engineer and Project Manager for a proposed liquefied natural gas (LNG) production, storage, and distribution facility in Charlton, Massachusetts. The NEC facility is being developed as an intrastate facility, meaning that it will fall under the jurisdiction of the Massachusetts Energy Facility Siting Board (EFSB) and Department of Public Utilities (DPU). Natural gas will be taken off of the Tennessee Gas Pipeline (TGP) system, treated, and converted to LNG in a nitrogen recycle liquefaction system and then stored in a full containment, field-erected storage tank. The LNG in the storage tank will then be transferred to tanker trucks that will deliver the LNG to existing utility-owned LNG peak-shaving facilities in New England.
Weston & Sampson has provided technical and project management expertise for the siting, preliminary engineering, and permitting of the project including assisting them with contract negotiations with the engineering, procurement, and construction (EPC) contractor and technology vendor. We also evaluated multiple interconnection points and pipeline lateral routes off the TGP system to provide feed gas to the facility. For the permitting of the project, we prepared the technical sections of the EFSB petition document and are coordinating permitting activities with the project’s environmental consultant and state agencies.
We are continuing to provide technical and project management support through the approval process with the EFSB and other state agencies along with negotiations with the EPC contractor and technology vendor. Weston & Sampson was chosen by NEC because of our wide range of engineering, environmental, and construction-related services, and our knowledge of the local area. This project will be instrumental in meeting the peak winter natural gas needs for both utilities and potentially power generators in the region. Detailed design and construction are expected to start in a few months.
