The Keystone Pipeline may not have been built, but TransCanada (NYSE:TRP) continues to be a major player in the midstream energy business. Tyler Crowe, in this video, explains how TransCanada not only moves oil, but also moves natural gas, and produces electricity from a variety of sources (e.g. natural gas, hydroelectric, or nuclear).  While the current P/E is a bit high, TransCanada plans on spending $12 billion in the next three years on building out its business. This buildout should add significant revenues, and makes the company worth the high multiple it sells for.
