Utilities worldwide are undergoing a fundamental transformation driven by digital technologies, advanced metering infrastructure (AMI), distributed energy resources, decarbonization initiatives, and rising customer expectations. Today's utility customers expect the same intuitive, personalized, and always-available digital experiences they receive from banking, retail, and telecommunications providers. They demand instant access to account information, transparent billing, digital payments, proactive notifications, and intelligent recommendations that help them better manage their energy or water consumption.
