Cal-PX Halts Market Ops; Going Out of Business

LCG, Jan. 31m 2001--The California Power Exchange said yesterday that it would no longer operate its day-ahead and day-of energy markets. The move is in response to a Federal Energy Regulatory Commission order that it recalculate all transactions made so far this year.

When FERC set its "soft cap" of $150 per megawatt-hour it eliminated a rule that all clearing prices be at the highest price bid and pay only the actual price bid. Cal-PX ignored that portion of the order and requested a stay of the order and a rehearing with the U.S. Ninth Circuit Court of Appeals. The court is scheduled to hear oral arguments on February 7.

"Regrettably, Cal-PX must take this extraordinary action in response to FERC's order that directs us to immediately comply with the terms of its December 15 order and implement a $150 breakpoint," Cal-PX president and chief executive George Cladode said in a statement.

Cal-PX said market participants stopped doing business with the exchange following the FERC order and defaults by Southern California Edison Co. and Pacific Gas & Electric Co. only made matters worse.

"The continuing defaults in our markets and threats of defaults in the next couple of days make it ridiculous to keep the market going when you're a public benefit corporation that's revenue neutral," said Cal-PX spokesman Jesus Arredondo.

The quasi-public agency said it is in the process of winding down operations in order to shut its doors.
