Solomon‘s cost analysis of 180 pipeline projects dates back to 2004, as shown in the figure. Average estimated cost for proposed pipeline projects in North America is double the cost in 2007 due to higher steel, labor, and other costs. Huge investments will be required in North America pipeline infrastructure, particularly in the Northeast region, where gas is growing quickly due to low full-cycle costs. The US Northeast has the highest average pipeline costs. Western Canada experienced significantly higher pipeline costs than in prior years. New pipeline systems are required to move US Shale gas supplies to the US Gulf Coast and Mexico. These are large-diameter (up to 48-inch) pipelines with overall capital costs ranging from 0.2MM USD to 3B USD, adding over 2,000 miles of new pipe to existing gas pipeline infrastructure by 2017 if all projects are completed. Mexico’s Federal Electricity Commission has announced five new pipeline projects.
