Canadian natural gas imports from the United States jumped by 14% last year, according to a trade scorecard kept by the National Energy Board (NEB).

Northbound cross-border pipeline deliveries averaged 2.4 Bcf/d in 2017, up from 2.1 Bcf/d the year before.

Canadian exports to the U.S., while down about 20% from their peak a decade ago, held on as the biggest item in the North American gas trade by scoring a 1% gain to 8.2 Bcf/d in 2017 from 8.1 Bcf/d in 2016.

Last year included the first three months of a discounted toll service on TransCanada Corp.’s gas Mainline from Alberta to Ontario, Quebec, and border crossings into the U.S. Shippers and the pipeline negotiated the bargain to make long-distance deliveries from western Canada competitive against Appalachian shale gas closer to eastern markets.

But as measured by growth, instead of sheer bulk alone, American exports were the 2017 North American natural gas champions in revenue as well as volume increases.

The value of U.S. gas exports to Canada jumped by 33% to CDN$3.6 billion (US$2.9 billion) in 2017 from CDN$2.7 billion (US$2.2 billion) in 2016.

Canadian cross-border gas revenues increased only half as fast as the American export pace, rising by 17% to CDN$10.3 billion (US$8.2 billion) in 2017 from CDN$8.8 billion (US$7 billion) in 2016.
