The oil industry has been a brutal place in recent years. Crude price volatility has led oil producers to drill fewer wells, which has impacted the volumes flowing through North America’s pipeline networks. While that has hurt some midstream companies, it hasn’t affected Canadian energy infrastructure behemoth Enbridge (NYSE: ENB) because its rate structure insulates it against fluctuations in commodity prices and volumes. As a result, its fourth-quarter results were solid, with earnings before interest, taxes, depreciation, and amortization of 3.201 billion Canadian dollars. This is an energy company that has plenty of fuel to continue growing its cash flow and high-yielding dividend.
