Three such companies are Brookfield Renewable Partners (NYSE: BEP), NextEra Energy (NYSE: NEE), and Brookfield Infrastructure Partners (NYSE: BIP). Add those investments to the inflation-related growth baked into its existing contracts and its upside to higher future power prices, and Brookfield Renewable anticipates that it can expand cash flow by 6% to 11% annually. Add in its investments in natural-gas pipelines and electricity transmission, as well as its ability to acquire assets, and NextEra Energy should have the power to grow earnings by a 6% to 8% annual rate for the next several years.
