Expire

Northern Natural Gas allowed to expire Monday a System Underrun Limitation that had been in effect for all market-area zones from Friday through Sunday.

Pacific Gas and Electric allowed a systemwide high-inventory OFO to expire Sunday after it had been in effect for the previous three days.

With hearings set to begin in June, Pacific Gas and Electric Co. (PG&E) is betting its short-term future on a $1.1 billion general rate case targeted to be effective at the start of next year with smaller interim revenue increases in 2012 ($275 million) and 2013 ($343 million). But the California Public Utilities Commission’s (CPUC) independent consumer unit, the Division of Ratepayer Advocates (DRA), has come out of the gate drawing its line in the sand at a revenue level less than 25% of what the utility asked for in its CPUC filing.

After allowing a previous high-linepack OFO to expire Monday, Southern California Gas (SoCalGas) declared a new one for Wednesday, setting a positive daily imbalance tolerance of 10%. However, the e-mailed OFO notice did not get sent until shortly after 7:30 a.m. CDT Wednesday morning. Spokeswoman Denise King confirmed that despite the late announcement, Wednesday was the effective date of the OFO. SoCalGas also said Wednesday it had completed the final tie-in of field Line 159 at its Goleta storage facility; the work previously had been expected to last through Friday. The early finish allowed the utility to restore 140 MMcf/d of withdrawal capacity and 60 MMcf/d of injection capacity at Goleta.
