FERC Judge Finds El Paso Withheld Natural Gas

LCG, Sep. 23, 2002--During the period Nov. 1, 2000, to Mar. 31, 2001, El Paso Natural Gas failed to release gas supplies to California that could have been used to provide electric power, a Federal Energy Regulatory Commission judge ruled today.

The ruling by Chief Judge Curtis Wagner stated that "El Paso Pipeline withheld extremely large amounts of capacity that it could have flowed to its California delivery points and in violation of its 10-year settlement agreement, which substantially tightened the supply of natural gas at the California border significantly, broadening the basis differential."

The company's chairman, William Wise, said in a statement, "We are disappointed that today's proposed decision does not recognize the substantial record evidence supporting El Paso Natural Gas' position that the pipeline was operated properly."

The ruling reflected a change in Wagner's assessment of El Paso's role in the power market. Last fall, the judge did not find evidence that El Paso had manipulated the market. Today's ruling was based on his conclusion that extra supplies of natural gas had been available to El Paso at the time.
