NERC's New Winter Reliability Assessment Raises Concerns for Elevated Risk of Insufficient Supplies to Meet Demand in Extreme Operating Conditions

Reliant Says it Needs to be Paid for California Electricity

LCG, Jan 9, 2001Reliant Energy Inc., in an emergency filing with the Federal energy Regulatory Commission yesterday, asked the agency to disallow any efforts by the California Independent system Operator to relax credit provisions of its tariffs.

In a filing last Thursday, Cal-ISO asked to modify its tariff so that California's investor-owned utilities would not need to provide payment security to purchase electricity. Reliant said Cal-ISO's proposal would "force the financial uncertainty of the near-bankrupt California electric utilities on suppliers across the entire western region."

In its emergency filing, Reliant also asked that FERC act to ensure that power suppliers selling to the Cal ISO are given reasonable assurance of payment for their deliveries.

"Reliant Energy has taken extraordinary actions to keep its generation facilities available to meetelectricity demand in California and has no desire to interrupt its deliveries now," said chief executive Steve Letbetter. "But the Cal ISO's recent action raises anew the need for assurance that all suppliers in the West will be paid for their sales of energy to the California markets."
