Power Suppliers Allege Entergy Exerted Market Power

LCG, Jan. 28, 2002--A filing by twelve power generators with the Federal Energy Regulatory Commission charges that imbalances from under-deliveries by Entergy reflect "unjust, unreasonable and unduly discriminatory rates."

The complaint, submitted on Jan. 10, is based in part on a November 2001 ruling by the FERC that Entergy was capable of exercising market power. FERC's order said that the rates charged by Entergy were to be cost-based rates when no long-term contract applied, with an exception for areas controlled by a regional transmission organization.

The firms, which include Mirant Corp., Reliant Energy Inc., Williams Cos., and Exelon Corp., cited Entergy's stated incremental costs, $100 per megawatt-hour in excess of the market clearing price in the market that showed imbalances, or hourly gaps between scheduled and actual usage.

A statement by the generators said, "Entergy retains the ability to charge customers excessive rates, it retains the ability to deny customers comparable service, and it continues to violate the commission's standards of conduct." Entergy, based in Louisiana, serves customers in Arkansas, Louisiana, and Mississippi.
