Calpine May Renegotiate California Power Contracts

LCG, Dec. 12, 2001--Calpine Corp. said yesterday it will meet later this week with California state officials to discuss long-term power contracts between the independent power producer and the California Department of Water Resources.

The contracts, negotiated last spring when the state was facing a future of rolling blackouts due to power shortages, are for electricity at prices significantly higher than the current spot market price of $25 per megawatt-hour.

The CDWR, which signed $43 million worth of those contracts at an average price of $69 per megawatt-hour, has been under intense pressure to renegotiate them.

Calpine did not say it would rewrite its contracts to give the state a better price.

"Calpine and the state stand behind their respective contractual obligations. However, we are open to working with (the CDWR) to explore options that can add value for both parties," said James Macias, Calpine's lead negotiator for the contracts.

Under two contracts, Calpine has contracted to provide the CDWR with up to 2,000 megawatts of baseload power and up to 735 megawatts of peaking power, all of it from its own natural gas-fueled power plants.

Because Calpine, at the time the contracts were negotiated, let contracts for the supply of natural gas fuel for the plants at then-high gas prices, it would be difficult for the company to now reduce the amount it is to be paid for the power, observers say.
