India's power system in India is rapidly decentralizing through the expansion of rooftop solar, electric vehicles, and distributed generation, driven by the smart metering rollout under the Revamped Distribution Sector Scheme. The focus is on achieving financial sustainability for distribution companies, reliability for consumers, and supporting renewable energy ambitions. Decentralized RF mesh networks are crucial in connecting millions of devices reliably and affordably, while the ecosystem model promotes collaboration among multiple vendors, making the system more resilient and responsive. India's approach to smart metering, focusing on interoperability and transparent performance validation, sets global benchmarks and shows that decentralization is a practical path towards a resilient grid in the transition to a high-renewables grid.
