Iroquois

The development of Appalachia’s Marcellus and Utica shales has flipped regional natural gas prices in the U.S. Northeast from their long-time premiums to Henry Hub, to trading at a significant discount and, in the process, reversed inbound gas flows, including from Eastern Canada. But there is an exception: from an entry point at the northern edge of New York, the Iroquois Gas Transmission pipeline is still importing Canadian gas supply nearly year-round to help meet local demand, despite its proximity to Marcellus/Utica production via other Northeast pipelines. This has kept prices along the Iroquois pipeline system at a premium to the other points in the region. And with the new, 1,100-MW Cricket Valley Energy Center power plant due online this spring, Iroquois prices are likely to strengthen. Today, we examine the dynamics driving Iroquois prices and gas flows.

As we stated in Part 1 of this series, New York City will need increasing amounts of natural gas as it continues its shift from oil-fired power plants and oil-based space heating. New gas pipeline capacity to and through the Big Apple has been added as recently as May 2015, but the nation’s largest city still faces wintertime gas-delivery constraints that cause costly spikes in gas and power prices. Given the challenges of adding new pipeline capacity in one of the most densely populated parts of the U.S., developer Liberty Natural Gas is planning an offshore liquefied natural gas terminal that by late 2018 would inject gas into the city’s existing pipeline network on an as-needed basis. Today, we continue our look at the economics of using imported LNG to supplement gas supplies in the Northeast.
