Proposed Carty Lateral Project
Gas Transmission Northwest LLC has been asked by Portland General Electric Company (PGE) to seek a permit from the Federal Energy Regulatory Commission (FERC) to construct a natural gas pipeline lateral in north-central Oregon to serve a proposed electric generation facility.

Project Benefits

Natural gas transported on the proposed Carty Lateral will be used as a fuel to make electricity at the proposed Carty Generating Station, to be owned and operated by PGE. The electricity made at the plant will help meet the needs of PGE’s 800,000-plus customers.

Natural gas is an environmentally responsible fuel, and advances in drilling technology have vastly increased North American supplies. The proposed Carty Lateral will provide ready access to a steady supply of natural gas.

  • April 2011 through June 2012: GTN conducts Pre-Filing Process with FERC, including public and agency consultation, land surveys and environmental studies.
