Downeast LNG will construct and operate a LNG liquefaction project in the Town of Robbinston, Maine. The project will be capable of liquefying an average of approximately 450 mmcfd of pipeline-quality natural gas (including fuel and inerts) or 3 million tons of LNG per year. If market conditions warrant, the project will also have the capacity to regasify up to 100 mmcfd in the vaporization mode.
The Downeast LNG project will liquefy natural gas into LNG and store it in a 160,000 m3 full containment storage tank. LNG will be exported by LNG carriers at the project’s marine terminal via marine transit of Head Harbour Passage. An estimated 50 to 60 ship transits will occur annually.
The Downeast LNG project has been proposed due to the increased natural gas production in North America, specifically drilling productivity gains that have enabled rapid growth in supplies from unconventional, and particularly shale, gas-bearing formations. The export of natural gas as LNG would provide a market solution to allow the further development of these emerging sources of natural gas.
While the Project is principally an export facility, it will also have the ability to reduce its liquefaction rate on the coldest winter days. By making its gas available to Maine and New England consumers the project will alleviate shortages of natural gas during the peak demand months in the winter. The storage capability of the terminal may allow it to also act as a peak–shaving facility during the peak demand periods. In addition, the terminal can be an import terminal with natural gas sendout capacity should current market dynamics shift dramatically in the future.
