Cold Boosts Gas Prices to Two-Year Highs
LCG, Jan. 24, 2002--Seasonal price fluctuations and unusually cold weather in the Eastern part of the U.S. have brought natural gas prices to two-year highs, and resulted in some power plants being taken out of operation.In the Tennesse Valley Authority (TVA) service territory, temperatures on Thursday resulted in an all-time winter record for system power demand. Record low temperatures were recorded in much of the Southeast, in some cases by as much as ten degrees below the previous record. Areas further to the north are experiencing prolonged low temperatures in the single digits.The continued low temperatures and increased use of gas for heating have brought gas prices to levels at which some power marketers engaged in tolling agreements with power plant owners (the marketers obtain the fuel needed to run the plant and pay the plant owner for the right to sell the output) have sold gas supplies rather than run the plants. Williams Energy Marketing, for one, has made little use of the Ironwood and Red Oak power plants in Pennsylvania and New Jersey for the past few months. Rather than utilize the plants, owned by AES Corp., Williams has been buying power from other sources while making profits from its gas supplies.Prices for gas have remained elevated due to ongoing high levels of consumption. At the same time, the amount of gas in storage is falling relative to 5-year average levels. Some analysts are projecting that if the trend continues, prices could reach $8/mmBtu this quarter.
