Brookfield Infrastructure (NYSE: BIP)(NYSE: BIPC), Camden Properties (NYSE: CPT), and Xcel Energy (NASDAQ: XEL) should deliver steady dividend growth for years to come -- making them perfect for retirees' portfolios. Supporting that view are contracted rates that will rise with inflation, planned expansion projects, and the company's ability to maximize its earnings via cost reductions and other initiatives. Powering that plan is a multibillion-dollar expansion program to enhance its operations and slowly transition its fuel sources to cleaner, renewable energy options.
