High BTU Gas Expected October 24, 2008

Thursday, October 23, 2008

Pacific Gas and Electric Company's California Gas Transmission expects to receive higher-than-normal heating value gas into its system starting at Malin, Oregon, at approximately 1:00 p.m. Pacific time on Friday, October 24, 2008. The high BTU gas delivery, due to unexpected maintenance at a facility located in Canada, is expected to last for one day.

The speed at which the high BTU gas will migrate throughout the system is dependent on the system demand pattern experienced by the local transmission and distribution systems. The BTU value of the delivered gas is expected to be between 1070 and 1085 BTU/cf, which is above normal levels of 1020 BTU/cf.

The BTU content throughout PG&E's system will remain within existing parameters for safe and reliable equipment operation. However, some customer processes may be sensitive to natural gas heat content, especially electric generation facilities, refineries, glass manufacturers and commercial customers using natural gas for cooking and drying. Customers testing their emissions may notice the increased BTU content.
