Spectra Energy Corp successfully completed its New Jersey-New York Expansion Project. The new pipeline, an extension of Spectra Energy’s Texas Eastern and Algonquin Gas systems, is designed to bring approx. 800 million cubic feet per day (mmcf/d) of natural gas supplies, as well as economic and environmental benefits to this region. This first natural gas pipeline into Manhattan in 40 years is expected to lower energy costs and keep air cleaner.
The New Jersey-New York expansion is a USD 1.2B privately funded expansion of the Texas Eastern Transmission and Algonquin Gas Transmission pipeline systems. It involved laying approximately 20 miles of new pipeline (including about five miles of replacement pipeline); setting up new meter and regulating stations; and modifying existing facilities. It has a capacity of up to 800 mmcf/d, enough to heat 2M homes per day. Customers in New Jersey and New York projected to save an estimated $700 million annually in wholesale energy prices through this project.
Construction of the expansion included drilling nine tunnels (Horizontal Directional Drills, or HDDs) to route the pipe under rivers and streets, one of which holds the industry record for the longest 30-inch HDD in North America—the crossing at the Kill Van Kull—at just over 8,100 feet.
