Boston, MA (PRWEB) October 09, 2013
Gas-fired generation continued to lose ground to coal for the month of September when compared to September 2012. Gas-fired generation fell by 10% (10,421 GWh) and was primarily replaced with coal-fired generation which was up 5% (6,486 GWh) year-over-year. Stronger renewable and nuclear generation also helped displace gas. In the California ISO, wind generation was up 77% last September, primarily due to the build out of wind capacity in the region.
Power demand saw a slight increase from September 2012, particularly during the first two weeks of the month. Above normal temperatures in much of the Midwest and south-central areas of the U.S., coupled with a few key unplanned coal outages, helped give gas-fired generation some life and spur real-time volatility in the power markets. September 11 was the second highest real-time West Hub settle of the year at $107/MWh as Genscape’s monitors picked up coal outages at John Amos, Harrison, Conesville, and JM Stuart. At the same time monitored gas-fired generation in the RFC region increased 27% for the week.
During the same week, the South Central region of the country also saw an uptick in gas-fired generation as coal backed off. Genscape noted decreased generation from JK Spruce, Oklaunion, and Monticello, as well as a reported explosion at the JT Deely facility. For the month, on-peak average prices at ERCOT’s North Hub averaged $43.11/MWh; up 49% from September 2012 when prices averaged just $28.98/MWh.
Henry Hub prices rose 6% from August and were 24% higher than a year ago, while on the coal side only Powder River Basin prices were higher than a year ago. Genscape estimates delivered PRB prices to be in the $2.39-$2.84/MMBtu range for the month of September; still very much “in-the-money” when compared to gas.
Through the end of September, year-to-date coal-fired generation is 6% higher than 2012 while natural gas is 9% lower. After a weaker summer total power demand has fallen behind by 1% (38,861 GWh).
