The U.S. Energy Department revealed natural gas stockpiles only increased 65 billion cubic feet in the week ended June 3, compared to expectations for a 79 bcf gain, reports Christian Berthelsen for the Wall Street Journal.
Nevertheless, the lower-than-expected rise in gas storage is still 32.1% above average for this time of the year. Overall natural gas inventory levels are still near 3 trillion cubic feet. Unless strong summer heat fuels demand for electricity-powered cooling, stockpiles could test physical storage limits of 4.3 trillion cubic feet at the end of October.
Natural gas prices have been strengthening since May on expectations of strong demand for gas-fired electricity generation to meet higher air conditioning needs ahead of forecasted above-average temperatures for the summer.[related_stories]
