FERC Orders Some California Power Refunds

LCG, Oct. 9, 2001--The Federal Energy Regulatory Commission has ordered four energy firms to repay California and 10 other Western states for overcharges on electricity they sold in July at prices exceeding price caps imposed by FERC in April.

In its April 26 order, FERC said that charges exceeding the caps must be justified by the producer or refunds would be required. Two of the firms failed to justify their charges and two didn't try hard enough.

Reliant Energy Inc. and Williams Energy, a unit of The Williams Cos., did not provide sufficient support for their arguments that they needed to exceed the price caps. Mirant Corp. and Dynegy Inc. filed their paperwork late, leading the commissioners to reject their arguments.

In its ruling, FERC said the four companies "must refund amounts in excess of the mitigated price."

We are not talking about a lot of money. The amount California is due to get has been estimated as only $260,000, and the state spent about $1.5 billion for power in July.

FERC did not reveal how much each of the four companies owed, but a Mirant spokesman said his company was ordered to refund $33,800.

Though the dollar amounts are small, officials with Reliant and Williams said their companies planned an appeal.

FERC could not be reached for details yesterday because of the Columbus Day holiday.
