Natural gas in storage rose 67 billion cubic feet in the April 28 week to 2,256 bcf. The fifth consecutive weekly increase since the traditional end of the heating season on March 31 and the start of the injection phase of the annual cycle puts gas stocks 13.7 percent below last year's oversized level, bloated by lower than average heating consumption due to mild weather. Gas stocks are 15.5 percent higher than the average for the comparable period in the last 5 years, however, and remain in the upper half of the 5-year historical range. The E.I.A.'s short term energy outlook expects an increase of about 1,750 bcf through this summer's injection season, suggesting inventories at the end of October will not match the record high end-of-injection period levels set in October last year. The long term trend for gas consumption shows electricity generation drawing on gas supplies to a rapidly increasing extent. The heating season may be becoming a smaller factor for gas storage levels, given that gas has overcome coal for the first time in 2016 for electricity generation, producing 33.8 percent of the nation's electric power.
