The electric sub-meter market is poised for significant growth, with its value projected to rise from USD 16.69 billion in 2025 to USD 31.92 billion by 2035. The market is projected to grow at a CAGR of 6.7% during the forecast period. This growth is primarily fueled by rising urbanization, expanding energy demand, and the increasing need for accurate consumption tracking across residential, commercial, and industrial settings. These devices are becoming critical for energy efficiency, enabling property owners, tenants, and facility managers to track consumption at the unit level for better cost allocation and reduced waste.
As sustainable resource management gains momentum, sub-metering’s role in ensuring transparency and accountability is rising across both developed and developing economies.
Looking ahead, adoption will accelerate with smart-city programs, dynamic pricing models, and green-building certifications. Utilities and property developers are deploying wireless, IoT-enabled meters with real-time analytics that transform traditional metering into intelligent systems for predictive energy management and demand-side optimization.
As digitization deepens and energy conservation becomes a regulatory and corporate priority, unit-level metering is poised to become a core component of modern building infrastructure, supporting net-zero targets and lowering operating costs.
Government regulations significantly influence the industry, particularly in promoting energy efficiency and transparent billing practices. Regulatory bodies across major economies have made sub-metering mandatory for multi-unit buildings to ensure fair consumption tracking and reduce system losses.
The USA Department of Energy supports sub-meter deployment under programs like the Energy Efficiency and Conservation Block Grant (EECBG), while the European Union’s Energy Efficiency Directive enforces individual metering standards. In India, the Bureau of Energy Efficiency (BEE) recommends sub-metering in large commercial facilities to meet national conservation goals. These mandates are driving the adoption of advanced metering systems and reinforcing the need for accurate, regulation-compliant solutions.

Digitization of Grid Infrastructure Drives Smart Sub-Meter Demand
Global utilities are digitalizing distribution networks to cut technical losses and enable time-of-use billing. Sub-meters that communicate via IoT protocols fit this agenda by delivering circuit-level data, predictive maintenance alerts, and automated reconciliation. Commercial complexes with dynamic occupancy profiles rely on them to allocate costs transparently, while industrial plants deploy them to track machine-specific kWh, improving overall equipment effectiveness.
Regulatory energy-audit requirements in Asia and North America are reinforcing adoption, and component cost declines are broadening access for mid-tier developers.
High Initial Installation and Replacement Costs Limit Adoption
One of the key restraining factors affecting the electric sub-meters market is the high upfront cost associated with installation and infrastructure upgrades. While electric sub-meters enable detailed energy tracking and cost allocation, their deployment often demands significant investment, particularly in older buildings that require extensive electrical system modifications.
Small and medium enterprises, along with residential users, often find these initial expenses challenging, limiting widespread adoption. Additionally, maintenance and replacement costs for advanced digital sub-metering systems remain comparatively higher, making potential users cautious about integrating such technology without clear, immediate returns on investment.
Smart City Funding Unlocks Large-Scale Sub-Meter Deployment Opportunities
National smart-city programs in China, India, and the Gulf Cooperation Council allocate multibillion-dollar budgets to energy-efficient infrastructure. Grant rules often need monitoring at the individual unit level in buildings with different uses, making advanced sub-meters eligible for funding. Public-private partnerships further boost scale by bundling metering with solar rooftops, EV charging corridors, and district cooling plants, creating ecosystem demand across residential blocks and commercial campuses.
