Spot power prices go down; spot gas prices go up

In an unusual occurrence, spot power prices are up in each of the 10 regions monitored by the Energy Information Administration (EIA), while spot natural gas prices were up in those same 10 regions.

Houston had the biggest drop in spot power price on Aug. 12, as its price decreased almost 34% to $44.50/MWh.

The Mid-Atlantic saw the highest increase in its spot natural gas price, gaining almost 20%. The Mid-Atlantic spot gas price, however, remained the nation’s lowest at $2.90/mmBtu.

The New York Mercantile Exchange (Nymex) price for September delivery of natural gas continues to inch closer to the $4 mark, being listed at $3.97/mmBtu.

The Midwest posted a spot gas price of $4.01/mmBtu with a low spot power price of $30.09/MWh. This resulted in a very low spark spread of $2.05/MWh.

Ninety-eight of the nation’s 100 nuclear power units are online and generating power. In addition, to the Exelon (NYSE:EXC) LaSalle 2 unit in Illinois, the NextEra (NYSE:NEE) Turkey Point 3 facility in Florida was also listed at zero generation on Aug. 12, according to the Nuclear Regulatory Commission (NRC).

On Aug. 11 Turkey Point Unit 3 experienced a manual reactor trip due to a loss of instrument air, according to an NRC report.
