NewsRelease

The Alaska Pipeline Project to Conduct Solicitation of

Interest in Pipeline Capacity

ANCHORAGE, Alaska – July 30, 2012 – The Alaska Pipeline Project (APP) announced today that it will conduct a non-binding public solicitation of interest in securing capacity on a potential new pipeline system to transport Alaska’s North Slope gas. The solicitation of interest will take place from August 31 through September 14, 2012.

The solicitation of interest is being conducted to identify parties potentially interested in making future capacity commitments on a pipeline system from the Alaska North Slope to a gas liquefaction (LNG) terminal at a tidewater location in south-central Alaska or to an interconnection point near the border of British Columbia and Alberta in Canada.

APP will conduct the solicitation of interest in accordance with the Alaska Gasline Inducement Act (AGIA), which requires TransCanada, as the AGIA Licensee, to assess market interest in a pipeline transportation system for Alaska North Slope gas every two years after its first open season.

APP has set a high priority on providing access opportunities for in-state natural gas to heat and power local homes, business and industry. All options being pursued under AGIA provide for a minimum of five delivery points for local natural gas connections in Alaska.

APP is a joint effort between affiliates of TransCanada Corporation and Exxon Mobil Corporation to develop a natural gas pipeline under AGIA. For more information, visit the project website at: www.thealaskapipelineproject.com.
