FERC: Cal-ISO Must Pay for Power it Bought

LCG, Nov. 8, 2001--The Federal Energy Regulatory Commission yesterday said the California Independent System Operator must come up with a plan within three months to pay an estimated $1.2 billion in past-due electric bills.

FERC also told the Cal-ISO to send an invoice to the California Department of Water Resources within 15 days for all transactions it made on behalf of Edison International Inc.'s Southern California Edison Co. and PG&E Corp.'s Pacific Gas & Electric Co.

The water agency will also have three months to file with FERC a schedule for paying Cal-ISO.

Editor's Note: We do not have a clue as to the details of interagency dealings between or among California state agencies. We do know that we would be hesitant about doing business with any of them.

The Department of Water Resources also seems to be a bit fuzzy about the details of some of its transactions and says it wants market information on bids and prices. Cal-ISO for some reason says it cannot turn that information over to market participants, which the water agency is.

The power producers also don't want the details made public, saying that would violate confidentiality clauses and expose trading strategies.

A spokesman for the Department of Water Resources said the agency can't pay Cal-ISO without "a proper accounting from the ISO. We don't know how much money is owed to each power generator because the ISO is not willing to give us a bill."

But then he defended the ISO. "We're not putting blame on the ISO. They have obstacles because FERC tariffs prevent them from sharing market sensitive information. We're trying to work this out and hopefully the FERC action will resolve the matter," he said.
