SDG&E Sees Record Demand, Curtails Gas to IT Customers

Record demand of 659 MMcf/d last week on San Diego Gas & Electric's system forced the utility to curtail about 120 MMcf/d of deliveries to six interruptible customers, including two power generators and four commercial and industrial customers in Southern California, SDG&E spokesman Art Larson said. Demand on the system Thursday would have exceeded SDG&E's capacity without the curtailments.

"We've had some very high power plant demand here as well as high residential demand due to cold weather." Demand for the 24-hour period ending at 7 a.m. Thursday morning was 544 MMcf/d with the 120 MMcf/d in curtailments. "It's actually higher than the record and would have gone beyond our capacity."

The curtailments are expected to remain in place contingent on the weather and power plant demand. "We've had demand from the three power plants of about 320 MMcf/d. When we owned those plants it was about 150 MMcf/d."

Larson said SDG&E has about 80 interruptible customers and only six have been interrupted so far in exchange for lower rates.
