SEATTLE - Enron Corp. manipulated the energy market practically every day during the 2000-2001 power crunch and gouged Western customers for at least $1.1 billion, according to audiotapes and documents released yesterday.
The records were uncovered by the same utility that last month released details of profanity-laced conversations in which Enron traders gleefully gloat about ripping off "those poor grandmothers" in California during the power crisis.
Snohomish wants an administrative law judge to order Enron to surrender up to $2 billion in ill-gotten gains. California politicians want Enron to reimburse customers there at least $8.9 billion.
The latest documents show that Enron manipulated the market on 473 of 537 days from January 2000 to June 2001, the utility said.
In one scheme, Enron made $222,678 in three hours by shipping power from California to Oregon, masking the original source of the power, then selling it back to California at highly inflated rates.
The records also show that Enron employed at least five other schemes, dubbed "sidewinder," "ping pong," "donkey punch," "spread play" and "Russian roulette."
In one of the transcripts, an Enron employee says, "If the line's not congested, I just look to congest it. ... If you can congest it, that's a moneymaker no matter what."
The documents also show that Enron maintained five sets of accounting records.
Enron refused to comment on the records, except to say it is cooperating with all investigations. Energy traders routinely kept tapes of their phone calls as a record of oral contracts.
Sen. Maria Cantwell, a Washington Democrat, used the evidence to demand a new investigation by the Federal Energy Regulatory Commission.
"When are you going to give justice to the individuals who have been hurt by this Enron market manipulation?" Cantwell asked. "If the federal oversight regulators aren't going to do their job, then they should get out of the way and quit obstructing justice."
A spokesman for the energy commission did not immediately return a call seeking comment.
An administrative law judge's finding that Enron should forfeit $32.5 million in unjust profits is pending before the commission.
Snohomish analyzed the records in hopes of defending itself against a $122 million lawsuit filed by Enron, which has accused the district of illegally breaking its contracts with the company. The utility claims the contract was void because Enron engaged in fraudulent business practices to drive up prices.
Enron has sued several other Western utilities for more than $500 million based on similar claims. If the Snohomish Public Utility District loses its case, the average cost to each of its 290,000 customers would be $420, the utility said.
Other companies have reached settlements stemming from the Western energy crisis. California parties have settled complaints with Tulsa, Okla.-based Williams Cos. for $1.4 billion and Houston-based El Paso Corp. for $1.7 billion. Dynegy Inc. and NRG Energy Inc. in April struck a deal to wipe out more than $280 million in unpaid electricity bills during California's energy crisis.
In April 2002, Constellation Energy Group Inc. of Baltimore reached a $2.5 million settlement with California, avoiding a state lawsuit that alleged Constellation overcharged it for electricity.
Enron filed for bankruptcy in 2001.
