FERC Extends New York ISO Price Cap

LCG, Oct. 25, 2001--The Federal Energy Regulatory Commission yesterday approved a request by the New York Independent System Operator for an extension of a price cap of $1,000 per megawatt hour for wholesale electricity bids handled by the ISO.

NY-ISO had asked the federal regulators to extend through April 30 of next year the prices caps which went into effect in July, 1999. If, as expected, power supplies in New York City and on Long Island appear to be marginal as next summer approaches, the ISO may ask for another extension.

Under those circumstances, it is likely that the price controls will remain in effect until the new, 11-state Northeast Regional Transmission Organization is operational.

In its order, FERC said it believed its decision "will promote price certainty and market participants' confidence in the New York ISO-administered markets, which will increase supply, improve reliability and ... lower energy prices."

The Northeast Regional Transmission Organization is one of four super-RTOs FERC wants to create to replace the smaller independent system operators and other organizations that have sprung up since electric industry restructuring took hold about five years ago.
