Portland Natural Gas Transmission System
Portland Natural Gas Transmission System (PNGTS) is a pipeline that spans New England from the Canadian border to pipeline connections in New Hampshire, Maine, and Massachusetts. Jointly owned by TransCanada Corp. (one of the largest energy infrastructure companies in North America) and Énergir (the largest natural gas distribution company in Quebec and Vermont), PNGTS has served gas utilities, industry, and electric generation plants in the region since 1999.
PNGTS is regulated by the Federal Energy Regulatory Commission (FERC). It is currently authorized to move 168 million cubic feet of natural gas per day on its 295 miles of high-strength buried steel pipeline. This is enough energy to heat 573,000 New England homes each day. PNGTS is currently seeking authority to expand its service capability by 42 million cubic feet a day, an increase of 25 percent in the amount of natural gas available to customers via the pipeline.
Customers have committed to supporting the full capacity increase, and no existing customers will be impacted in terms of rates or service. The project does not involve any construction or ground disturbance and can be achieved by increased deliveries from other pipelines.
