Siemens Secures Order For First US Carbon-Neutral Pipeline Compressors

Posted on May 13, 2009

Siemens Energy has received an order in the U.S. for the supply of three pipeline compressor trains from Ruby Pipeline LLC, a subsidiary of El Paso Pipelines. The pipeline compressors feature electric drives and will be deployed at the head station in Roberson Creek, Wyoming. Through the purchase of electricity from renewable energy sources, carbon offsets or renewable energy credits, Ruby will become the first CO2-neutral pipeline in the U.S.

The Siemens scope of supply encompasses three STC-SV(08-5-A) pipeline compressors, three 17-megawatt electric motors and three perfect-harmony drives. The 621-mile-long (1,000-kilometer-long) pipeline is around 42” (one meter) in diameter and will transport approximately 35 to 42 million cubic meters (1.3 to 1.5 Bcf) of natural gas per day from the Rocky Mountains to the west coast of the U.S. The pipeline will provide needed supply diversity to the states of Oregon, California, Idaho, Nevada and Washington. The equipment trains will be packaged at the company’s facility in Houston, Texas.

The Siemens pipeline portfolio encompasses compressors with electric drives or gas turbine drives, transformers, substations, breakers and automation, communications and safety equipment. These solutions contribute toward meeting customer requirements such as pipeline operational reliability, safety, efficiency and operability.

The compressor trains are scheduled to be shipped in the summer of 2010 and the pipeline is expected to begin operation in early 2011.
