CPUC Rejects Utility Request to Build New Natural Gas Pipeline in San Diego

 Permanent link   All Posts

Today we denied the request of San Diego Gas and Electric (SDG&E) and Southern California Gas Company (SoCalGas) to build a new natural gas transmission pipeline, finding it is not needed for safety or reliability.  The pipeline would have been named Line 3602.

The utilities were seeking CPUC approval to build a 47-mile long, 36-inch diameter natural gas transmission pipeline from Rainbow Station to Miramar, at a loaded cost of $639 million. The pipeline would have replaced a 16-inch natural gas transmission pipeline, Line 1600, which presently provides service from Rainbow Station to Miramar.  

The CPUC determined that the utilities' most recent natural gas supply forecast and the CPUC's reliability standard for gas planning do not demonstrate that there is a need for the proposed pipeline.

The CPUC ordered the utilities to pursue options for supply that may be needed in smaller amounts and for shorter periods of time in the coming years.  

The CPUC also ordered the utilities to ensure the safety of Line 1600 by proceeding with implementing all state laws and rules that apply to natural gas transmission pipelines.

The proposal vote on in proceeding A.15-09-013 is available at http://docs.cpuc.ca.gov/PublishedDocs/Published/G000/M216/K622/216622543.PDF.
