Week in Review for June 21-27, 2013

Although natural gas and electricity prices were relatively flat during the prior two-week period of June 6 through June 20, the bears made a run this week. For this seven-day report period, the average 12-month price for natural gas on the New York Mercantile Exchange (NYMEX) fell 6%. The 12-month average price for peak power on the PJM fell 4%.

The two variables credited for this week's price drop were storage and weather.

On the natural gas storage side, this week's injection was 95 Bcf. Last year at this time we saw an injection of 58 Bcf. Thanks to a recent run of larger-than-normal injections, the storage deficit has continued to shrink. We are now only 1.2% below the five-year average. The larger-than-expected injection placed downward pressure on energy prices.

On the weather front, the National Oceanic and Atmospheric Administration's 6-10 day outlook for July 3-7, 2013, called for cooler-than-normal temperatures east of the Mississippi. Cool weather means more natural gas is available for injection into the storage fields. Large injections reduce the storage deficits and tend to place downward pressure on energy prices.

Do not be lulled to sleep however. Summer has just started and hot weather is on the menu. The reason that hot weather impacts energy prices is because more and more power plants are consuming natural gas to meet the country's air conditioning needs.

According to the Energy Information Administration (EIA), "the consumption of natural gas by electric power generators has been increasing each year since 2009 as lower natural gas prices allowed natural gas fired generators to compete with coal fired generators."

For the period of 1990-2010, coal fired generators produced approximately 50% of the country's mid-summer electricity. During the peak summer months of 2012, coal produced only 39% of the country's electricity. The facts indicate that natural gas demand at the power plants is increasing. This means a hotter-than-normal summer can impact energy prices more than ever before.

Storage Update: One again, we saw another larger than expected injection this week. This week's injection was 95 Bcf.

Last year at this time, we saw an injection of 58 Bcf. The five-year average injection for this time period was 79 Bcf. Thanks to these large injections, the storage deficit continued to shrink. Natural gas inventories ended the week 17.1% below last year's levels. We are now only 1.2 % below the five-year average. As you may recall, on May 2, 2013, storage levels were 6.2% below the five-year average.

The traditional injection season runs from April 1 to October 31. If we keep pumping natural gas to the storage fields instead of the power plants, we may see some downward pressure on energy prices. However, summer just started and hot weather is on the way.

Rig Count for Natural Gas

Weekly Drilling Rig Update: The active U.S. gas rotary rig count for natural gas released by Baker and Hughes for the week ending June 21, 2013 was 349 rigs. This was a decrease of four rigs from the previous week. The count is 192 rigs lower than the count reported this same week last year. We are 61% below the five-year average gas rig count of 904.

****Cooling degree days are calculated by comparing the day’s average temperature to a 65 degree baseline.  If the day’s average temperature is below 65, there are no cooling degree days that day.  If the average temperature is greater than 65 degrees, then subtract 65 from the average temperature to find the number of cooling degree days.
