U.S. Net Natural Gas Imports Through First Third of 2012 Lowest Since 1990
Through the first four months of 2012, U.S. net imports (imports minus exports) of natural gas averaged just 4.5 billion cubic feet (Bcf) per day, down 26 percent from the corresponding period in 2011 and the lowest first third-of-year average since 1990. On an annual basis, U.S. net natural gas imports rose gradually from the late 1980s and peaked at over 10 Bcf per day in 2007. However, net imports have fallen sharply, the result of reduced imports and growing exports driven largely by significantly increasing domestic production associated primarily with shale gas development.
Pipeline shipments from Canada are by far the leading source of U.S. natural gas imports. Liquefied natural gas (LNG) is an important secondary source, but higher natural gas prices in competing overseas markets are attracting spot LNG cargoes that can be delivered under flexible pricing terms.
Natural gas prices rose over the report week at most spot market locations. The Henry Hub price increased from $2.84 per MMBtu last Wednesday to $3.19 per MMBtu yesterday. The largest price increases occurred in the Rocky Mountain area; for example, the spot price at the Opal Hub in Wyoming rose 51 cents from $2.48 per MMBtu last Wednesday to $2.99 yesterday. Various trade press and analysis reports have cited infrastructure issues in the price increases in the Rockies. A number of recent maintenance projects in the Rockies have limited outflow capacity, and recovery from maintenance provided support for prices.

Prices at a few Northeast trading points, particularly Tennessee Pipeline's Zone 4, fell during the week, reflecting infrastructure constraints. This week, spot prices at Tennessee's Zone 4 in the Marcellus Shale dropped from $1.84 per MMBtu last Wednesday to $1.39 per MMBtu yesterday. Prices at this trading point have, in the past several months, diverged from Henry Hub prices as Marcellus natural gas production has outpaced available takeaway capacity.
This report week marked the first time in 2012 that Henry Hub prices crossed the $3 per MMBtu threshold. Spot prices have generally risen since the end of April, and particularly from mid-June to the present, as demand for natural gas for power generation increased to meet air-conditioning needs. More natural gas power generation capacity has come online in recent years, and extreme heat and relatively low natural gas prices have pushed gas for power generation to historically high levels this summer. Power burn this week averaged 34.9 Bcf per day, 2.3 percent greater than last week and 1.8 percent greater than the corresponding week last year, according to data from BENTEK Energy LLC (Bentek). This week in the Southeast, the region's power burn exceeded last week's by 11.1 percent and the same week last year by 18.2 percent.
