Williams Provides FERC More Data on Export of California Power

TULSA, Okla. -- Williams (NYSE:WMB) is submitting information to the Federal Energy Regulatory Commission today showing that it did export power for higher prices outside of California in 2000 and 2001. Consistent with the company's trading practices, the price for that exported power was at or below temporary price caps that were in effect at the time. Williams is providing the information in response to the commission's June 4 order.

"Williams has continued to supply information on power exports to the commission, and FERC representatives were here last week at our invitation to review California natural gas market data. We will continue to cooperate fully with government regulators who are investigating the California energy crisis with the hope of bringing this matter to a prompt conclusion," said Steve Malcolm, chairman, president and CEO.

The complete written response will be made available on the Williams' web site at: www.williams.com, as soon as it has been received by the commission later today. Williams will be making its submission today rather than last Friday by verbal agreement with commission staff.
