California Gas Transmission will start receiving higher-than-normal heating value gas into its system around 3:00 p.m. PST on Thursday, June 8, 2023. The high BTU gas is coming in at the Gas Transmission Northwest (GTN) interconnect at Malin and has an expected duration of approximately 48 hours. The speed at which the high BTU gas will migrate through the system is dependent upon the system demand pattern experienced by the local transmission and distribution systems. The BTU value of the delivered gas is expected to be approximately 1080 BTU/cu ft, which is above normal levels of approximately 1030 BTU/cf.

The BTU content throughout PG&E's system is expected to 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.
