Pacific Gas and Electric Company's California Gas Transmission expects to receive higher-than-normal heating value gas into its system on Thursday evening, June 11, 2015. The high BTU gas will be coming in at the Gas Transmission Northwest (GTN) interconnect at Malin and has an expected duration of 48 hours. The BTU value of the delivered gas is expected to be as high as 1092 BTU/cf, which is above normal levels of 1020 BTU/cf, and is higher than our operating limit of 1080 BTU/cf.

In order to blend this high BTU gas with lower BTU gas to bring it within operating limits, the nominations for gas coming in at Malin from GTN will be limited to the total of scheduled volumes from the Timely cycle for gas day June 11, which is 1281 MMcf/d. 

That is, the total volumes scheduled at GTN Malin for the Evening nomination cycle and each subsequent cycle for approximately 48 hours, will be limited to maintain our BTU operating limits. The actual volumes scheduled, and the duration of the high BTU gas flow, are our best information at this time and are subject to change based on changing operating conditions.

If you have any questions about this information, please contact your CGT Account Manager.
