Avista Corp. to Testify Before FERC Judge on Market Behavior

LCG, April 3, 2003Federal Energy Regulatory Commission Administrative Law Judge Curtis L. Wagner, Jr. will hear arguments April 9 regarding whether or not an energy market manipulation investigation can be closed.

A year ago FERC began the process of investigating possible energy market manipulation. The commission ordered firms to respond to allegations of improper trading. Avista Corp,, among many other companies, has been subject specifically to a five-month investigation by FERC.

FERC investigators earlier found no market manipulation linked to Avista Corporation, and the Commission began the process of closing the file on Avista.

Now a FERC judge must determine whether or not all concerns raised regarding Avista have been met: no evidence has been found to show Avista Utilities or Avista Energy staff knowlingly participated in improper trading, manipulation of western energy markets, or withholding relevant market information during the FERC inquiry.

According to some sources, Judge Wagner has some reservations regarding the possible settlement, especially in light of a report issued by FERC staff recently that may show Avista involved in unfair trading arrangements.

Meanwhile, Avista is positive about the possible settlement and continues to oppose potential California refunds.
