Introduction

India has set an ambitious target of installing 25 Crore smart meters for consumers by 2022. Despite replacing 19 Lakh existing meters with smart ones, there’s a lack of robust accountability systems to ensure the effectiveness of this large-scale program. The shift from conventional meters to smart meters and solar panels goes beyond addressing metering and billing issues; it promises performance improvements like quicker outage detection, better service quality, and enhanced load management. India is on the brink of a significant transformation in how electricity billing and consumption data are managed, thanks to the rollout of advanced smart metering technology. This shift gained momentum after the Finance Minister’s announcement in the 2020 budget speech, outlining plans to replace all conventional consumer meters with smart meters by 2022. Subsequently, a scheme worth ₹3.05 lakh crore was introduced in the FY22 budget, with a substantial focus on smart metering. The Smart Meter National Program (SMNP), spearheaded by the Government of India through Energy Efficiency Services Limited (EESL), has already installed 19 lakh smart meters across the country. While the SMNP aims to replace 25 crore conventional meters, electricity distribution companies (DISCOMs) are also embracing smart metering initiatives. For instance, the Andhra Pradesh government plans to install about 18 lakh smart meters for agricultural connections. To fully realize these benefits, close monitoring of the program’s implementation is crucial. Smart meters will become the primary interface between consumers and DISCOMs (Distribution Companies). Malfunctioning metering systems could lead to significant inconvenience for consumers. Achieving large-scale implementation requires careful analysis, evaluation by regulators, and learning from pilot projects. In response to this backdrop, this article identifies key issues requiring immediate attention and provides recommendations for the stakeholders involved.

Smart Meters and Their Intended Benefits

Smart meters are advanced electronic electricity meters equipped with communication capabilities, allowing bidirectional communication, load limiting, remote firmware upgrades, net metering, prepaid/post-paid features, and time-of-day tariffs. They also store electrical energy parameters data for specified periods. These meters offer numerous benefits to both electricity distribution companies (DISCOMs) and consumers. For DISCOMs, smart meters aid in tracking Aggregate Technical and Commercial (AT&C) losses more efficiently, leading to improved revenue collection and demand-side management. They also contribute to loss reduction, enhancing billing and collection efficiency. Consumers benefit from smart meter for solar panels by gaining more control over their energy consumption through access to consumption history records. Additionally, smart meters enable better electricity supply quality by facilitating quicker outage detection and eliminating billing errors. Overall, smart meters are seen as a significant innovation to address challenges in the power sector and improve service delivery for both utilities and consumers. In the Indian context, both smart metering and net metering present unique challenges and opportunities that are crucial to understand for the effective implementation and management of electricity systems.
