Retail electricity tariffs have transitioned from uniform cost-recovery schemes to diversified packages that incorporate temporal, locational, and carbon-intensity signals. This paper reviews the evolution of retail pricing mechanisms, their global applications, and the design principles that underpin modern tariff innovation, and it further identifies electric-vehicle (EV) charging tariffs as a rapidly expanding subset within this broader transformation. Drawing on cases from the United States, the European Union, Australia, Japan, and China, the review traces the progression from traditional two-part tariffs to smart-meter-enabled time-of-use pricing, real-time dynamic rates, and subscription–dynamic hybrid designs. Core mechanisms – marginal-cost reflection, risk hedging, digital customer segmentation, and vehicle-to-grid integration – are evaluated in terms of system efficiency, cost recovery, and distributional fairness. Evidence shows that time-of-use pricing combined with automated control can reduce peak load by 5%–15%, real-time pricing pilots achieve up to 20% load shifting, and subscription-based EV tariffs lower annual charging expenses by 25%–35% while maintaining renewal rates above 90%. The analysis concludes that jurisdictions capable of integrating digital infrastructure, flexible regulation, and equity safeguards are best positioned to deliver retail tariff designs that are efficient, resilient, and socially inclusive.
