High BTU Gas Notice

Saturday, July 07, 2007

Pacific Gas and Electric Company's California Gas Transmission received approximately 8 hours of high BTU gas from Gas Transmission Northwest at Malin just after 1:00 p.m. Pacific time, Saturday, July 7, 2007. The BTU level of the delivered gas is expected to be between 1030 - 1053 BTU/CF, which is above normal levels of 1020 BTU/CF. 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 system for each area.

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.

Based on system conditions, the higher-than-normal BTU gas volumes are flowing rapidly through the system and are currently estimated to arrive in the:

  • Eureka area at approximately 11:00 p.m. today
  • Sacramento area at approximately 6:00 a.m. Pacific time Sunday, July 8
  • Santa Rosa area at approximately 4:00 p.m. Sunday, July 8
  • Stockton area at approximately 3:30 p.m. Sunday, July 8
