FERC Bars Data Sharing Between Cal-ISO, Water Agency

LCG, Nov. 21, 2001--The Federal Energy Regulatory Commission yesterday ordered the California Independent System Operator to stop giving preference to power bought from the state Department of Water Resources and to quit giving the water agency energy traders advance notice of the grid's electricity needs.

Power producers Mirant Corp. and Reliant Energy Inc. had complained to FERC that Cal-ISO was giving the state's energy traders preferential treatment by giving them access to information not available to other market participants. They also said Cal-ISO had purchased power from the CDWR at high prices when cheaper electricity was available.

FERC denied the companies' request for a formal investigation of Cal-ISO's relationship with the CDWR.

The ISO said it would comply with the FERC order, one way or the other. One way would be to share information with everyone -- the other would be to keep everyone in the dark about its power needs.

Reliant spokesman Richard Wheatley applauded FERC's action, saying it upheld the energy companies' complaints that "preferential treatment of certain market participants are not allowed."

Patrick Dorinson, a spokesman for Mirant, said his company was "pleased that FERC has clearly stated that DWR is a market participant and must follow the rules as we're all required to. In order to ensure a properly functioning market, we all have to be treated fairly."

The water agency didn't think it was being treated fairly. Spokesman Oscar Hidalgo said "The market rules seem to benefit the seller. I'm sure the rules didn't anticipate having a public agency as a participant. There was certainly no anticipation for a utility (Pacific Gas & Electric Co.) going under."
