Utility power companies are currently going through an energy transition. Many are actively investing in clean energy infrastructure, including solar, wind, battery storage and grid modernization. As the world moves toward decarbonization, utilities that are early adopters of renewables and low-carbon technologies stand to benefit from an expanded market and reduced fuel cost volatility, enhancing their appeal to institutional and retail investors alike.
