Kinder Morgan (NYSE: KMI) spent the better part of the last year working on high grading its backlog. What that means is that the pipeline company is purging lower-return projects while moving forward with its best options and looking for new opportunities to expand. It announced updates on those latter two initiatives this week, which is providing greater visibility into what will fuel its growth in the coming years.Earlier this month, Kinder Morgan announced that it had completed the final cost estimate for its Trans Mountain Pipeline expansion project in Canada.
