Yes, the NEP proposed extending some natural gas pipelines. You neglected to mention that it also imposed price controls and new taxes on oil and gas revenues.
Marc Lalonde, the minister responsible, literally said after the fact that the goal of the program was to shift oil and gas revenue from the provinces and industry to Ottawa:
"The major factor behind the NEP wasn't Canadianization or getting more from the industry or even self sufficiency," [...] "The determinant factor was the fiscal imbalance between the provinces and the federal government [...] "Our proposal was to increase Ottawa's share appreciably, so that the share of the producing provinces would decline significantly and the industry's share would decline somewhat."
