Gas Transmission Northwest LLC (GTN) has filed an application at FERC to build a 24-mile lateral to provide natural gas to a proposed power generating facility in northern Oregon.

The pipeline, which is operated by Calgary-based TransCanada Corp., proposes to build a 20-inch diameter line that would extend from GTN's Ione Compressor Station to Portland General Electric Co.'s (PGE) proposed Carty generating station in Morrow County, OR. The station would provide electric service to 800,000-plus customers. The lateral would have a design capacity of 175,000 Dth/d, according to GTN.

GTN has asked the Federal Energy Regulatory Commission to issue an order by April 1, 2013 so that the lateral can be completed and in service by the start of the heating season on Nov. 1, 2014. According to GTN, PGE has agreed to contract for the entire capacity of the lateral for a term of 30 years beginning on the in-service date.

GTN is 75% owned by an indirect subsidiary of TransCanada. The balance is owned by TC PipeLines, LP, a master limited partnership that is partly owned by TransCanada.

The 1,351-mile GTN system begins at the British Columbia-Idaho border, extends through northern Idaho, southeastern Washington and central Oregon, and ends at the Oregon-California border. The pipeline is able to transport more than 2.9 Bcf/d of natural gas. More than 2.1 Bcf/d can be delivered to California, and up to 1 Bcf/d to the Pacific Northwest (though typical deliveries there are 600-700 MMcf/d).
