California Gas Transmission announces the close of the Abnormal Peak Day (APD) window. What does this mean to natural gas shippers in northern California? The probability of an APD prior to next winter is nearly zero.

An APD represents a day so cold that such conditions are only expected once in 90 years. During an APD, Pacific Gas and Electric Company system composite temperatures would fall to 27.4 degrees Fahrenheit or lower, requiring involuntary diversions and/or local curtailments.

CGT does not expect extreme cold temperatures to occur across PG&E's gas service territory for the remainder of the winter season. Involuntary diversions or local curtailments driven by cold weather are now highly unlikely.

Please contact your CGT Account Services Representative if you have any questions about the APD window.
